1.2 General System Description
The Liebert FS is a flywheel energy storage system, a mechanical battery that stores energy in the
form of a rotating mass. This energy is immediately convertible to useful electric power.
The Liebert FS is available with a wide performance range up to 200kW as a single unit configura-
tion.
Figure 1 Liebert FS
The Liebert FS is configured as a two-terminal plus ground DC flywheel power system and is used as
a functional replacement for or an availability supplement to a bank of chemical batteries for an
Uninterruptible Power System. Like a chemical battery bank, Liebert FS receives charge and float
power from the two terminal UPS DC bus and returns power to the same DC bus whenever the bus
voltage droops below a programmable threshold level.
Integrated into a UPS, the Liebert FS is used as the alternate source of power to supply DC power to
the UPS inverter if the AC supply voltage (UPS input) is outside the acceptable range. The Liebert FS
supplies power to the UPS inverter until the utility power is restored, until an alternate power source
is available, or until the Liebert FS’ energy is exhausted.
One or more Liebert FS units may be integrated into UPS and can be put in parallel as shown in
Figures 2 and 3, to achieve higher power output or higher ride-through duration.

2.0 SITE PREPARATION
Site preparation for the Liebert FS is minimal. If a UPS system is already installed, the only require-
ments are to properly:
Place the unit in relation to walls, ceiling and other equipment and
Fasten the unit to the floor.
2.1 System Location
Choose a location for the Liebert FS that offers:
Easy connection to inputs, outputs and auxiliary equipment
Enough space to service the Liebert FS
Air circulation sufficient to expel heat produced by Liebert FS
Protection against moisture and excessive humidity (not to exceed 95% non-condensing)
Protection against excessive dust and other particulate matter
Compliance with fire prevention regulations and practices
Operating environment temperature of -4°F to 122°F (-20°C to 50°C)
2.2 Environmental Considerations
Place the system in a clean, dust-free environment. Air must be free to circulate around the cabi-
net(s). The system pulls air through the front of the Liebert FS and exhausts it out the top for cooling.
If the unit must be located in a dusty environment, Liebert recommends installing an optional air fil-
ter, which mounts on the lower inside of the Liebert FS door.
Adequate ventilation, including air conditioning if necessary, must be provided to limit heat accumu-
lation. The ambient temperature for the unit must be from -4°F to 122°F (-20°C to 50°C). Avoid plac-
ing the unit in direct sunlight or near other heat sources.
There is a 32°F (0°C) minimum ambient temperature requirement for starting up the unit. Once the
unit has been running for some time, it will keep itself warm enough in ambient temperatures as low as
-4°F (-20°C).
Humidity is not to exceed 95% (non-condensing).
!CAUTION
The following sections should be read thoroughly before proceeding with site preparation for
installing the Liebert FS.
NOTE
All drawings referred to in this section are in Appendix D.0 - Installation Drawings.
DISCONTINUED
PROD UC T
Site Preparation
11
2.3 Flooring Requirements
2.3.1 Floor Loading
The Liebert FS should be mounted on a finished surface, such as concrete, block, brick or wood. The
floor must be strong enough to support the equipment load and suitable for installation of an anchor-
ing kit with vertical floor loading properly calculated (assume 2,000 PSI or 140 kg/cm2 contact load at
caster wheels; this includes safety factors).
When installing on a concrete, masonry or stone floor, use the factory-supplied masonry fasteners
(anchors). The fastener manufacturer’s allowable shear load (parallel to floor) for these fasteners
is 2,030 lb. (9 kN) when mounted in normal-weight concrete (2,000 to 3,000 PSI; 140-210 kg/cm2)
of at least 3 in. (7.6cm) thickness.
If installing on a floor consisting of a material other than normal-weight concrete as described
above, the mounting should be capable of sustaining a shear load (parallel to floor) of at least
1,500 lb. (6.7 kN) for each of the four mounting points.
If installing on a raised floor that is less than 2 in. (5cm) thick or constructed of a material not
appropriate for the masonry fasteners provided or lag screw engagement, mount using through
bolts with nuts and large diameter washers as shown in Figure 155.
Full details for mounting the cabinet are found in 4.1 - Cabinet Floor Mounting.
2.3.2 Floor-Space Occupation
The Liebert FS cabinet requires a floor space of 23" wide by 33" deep (63 x 83cm), resulting in a foot-
print of 5.7 square feet (0.5m2).
2.3.3 Clearances
The Liebert FS installation requires a ceiling height of at least 7 ft. (214cm).
The unit occasionally vents air out of the top. Loose ceiling tiles above the unit may be moved by the
airflow. Ample clearance to access the cable connection at the top of the unit must also be provided.
All system electrical connections are to be routed through the top or side of the cabinet.
A 36" (91cm) clearance is required in the front of the unit for National Electrical Code (NEC) compli-
ance.
Maintenance access to all components is from the front; no side or back access is required for mainte-
nance. Either side of the system cabinet can be placed against walls (assuming minimum distance
from edge of floor). Repair may require access to the rear of the unit. In this unlikely instance, the
unit may need to be rolled out from its installed location (cabinet is on casters).
2.4 Electrical Considerations
2.4.1 DC Power Connections
Place the Liebert FS as close as practical to the interconnected UPS. The maximum distance allowed
between the UPS and the Liebert FS depends on power levels and the type of DC cables used. Liebert
requires sizing DC cables and placing the Liebert FS for a maximum of no more than 2V loop drop (at
rated power) between the UPS and the Liebert FS.
The Liebert FS is delivered with the standard UPS interconnection kit for connection of the positive
and negative terminals coming from the UPS DC bus or from an external disconnect switch.
For details, see 4.2.2 - DC Power Connections.
NOTE
The above loads (both the fastener manufacturer load and the minimum mounting load)
include the required safety factors.
!CAUTION
A qualified electrician must perform all electrical connections. The wires (DC power,
grounding, optional status/control and auxiliary power supply) that connect the Liebert FS
system(s) to the UPS system must be provided by the electrical contractor (standard) or by
Liebert as an option. Wire size and installation must comply with all applicable local, regional
and national regulations (e.g., National Electric Code for USA).
DISCONTINUED
PROD UC T
Site Preparation
12
2.4.2 Status/Control Connections
Site preparation for Status/Control connections vary according to the type of UPS interconnection kit
provided with your Liebert FS.
Liebert recommends making Status/Control connections on the UPS system side.
For details, refer to 4.2.3 - Status/Control Connections.
2.4.3 Grounding Connections
A grounding wire must be connected from the Liebert FS to the UPS ground terminal. Identify in
advance the location of the grounding terminal on the UPS system. For further details, see 4.2.2 - DC
Power Connections.
2.4.4 AC Power Connections
Plan for the availability of a dedicated 110 or 230VAC, 50 or 60Hz circuit with branch circuit protec-
tion as a source for AC auxiliary power supply to the Liebert FS. This AC power must be rated for
500VA and must be located either on the output circuit of the UPS system or on another UPS-pro-
tected circuit. A qualified electrical contractor should make arrangements for this connection to be
permanent.
The field-supplied AC wire must comply with all applicable local, regional and national regulations
(e.g., National Electric Code for USA). An 18 AWG (0.82mm2) cable is recommended for this connec-
tion.
For details, see 4.2.5 - AC Auxiliary Control Power Supply Connections and Appendix F.0 -
Auxiliary Backup AC Power Supply.
2.4.5 Remote Monitoring Connections—Optional
If the optional Data Collection Module (DCM) is provided with your Liebert FS system, plan to have
communication cables (local network connection, phone line) installed to support the remote notifica-
tion and/or monitoring options chosen.
For details, see 4.2.6 - Remote Monitoring Connections—Optional.

mounting brackets and two banding straps. These same two mounting brackets are used to mount the
cabinet to the floor.
Packing elements should be removed in this order to ease unpacking:
1. Cut and remove the banding straps (see Figure 8).
2. Remove hex head bolts holding mounting brackets to pallet as shown in Figure 9.
3. Remove lag bolts holding metal mounting brackets to pallet.
4. Remove mounting brackets from Liebert FS.
Figure 9 Removing lag bolts
!CAUTION
Exhibit care when handling Liebert FS cabinet to avoid equipment damage or injury to
personnel. Failure to do so could throw off the calibration of the mechanical components
contained in the unit and possibly cause permanent damage.
!CAUTION
The Liebert FS has sensitive electronics and mechanical components that have been
calibrated prior to shipment.
!CAUTION
Test lift and balance the cabinet before transporting it. Maintain minimum tilt from vertical
at all times—do not exceed 15 degrees of tilt.
!CAUTION
Sheet metal components and framework may have sharp edges.
!CAUTION
Use care when removing banding straps and metal mounting brackets. The banding straps
are under tension and may snap violently, causing injury. Always wear proper eye and foot
protection when unpacking or installing the system.

4.0 INSTALLATION
The Liebert FS system design and safety characteristics allow for a relatively simple and quick instal-
lation. The system is designed to be rolled or lifted into place and bolted to the floor using Liebert's
mounting kit, included with the system. The mounting kit in most cases does not require any special
floor preparations (see3.0 - Unloading and Unpacking).
Figure 14 Dimensions, general layout
!CAUTION
The Liebert FS system must be installed in accordance with the instructions and drawings in
this manual.
!CAUTION
Never attempt to install or power up any unit suspected of damage during shipment.
!CAUTION
The Initial System Startup must be performed ONLY under the supervision of a
Liebert-certified service technician to ensure proper system operation. Failure to abide by
instructions provided herein may void your warranty.

NOTE
The Liebert FS is designed for front-access-only for installation and maintenance. While the
likelihood of repair is minimal, some repair procedures require side and/or rear access.
Normally, the easiest way to handle this is to disconnect the power and control wiring and roll
the unit out into an open area on its casters. While it is acceptable, under certain
circumstances, to connect the Liebert FS to its companion UPS unit through the sides of the
Liebert FS and UPS cabinets rather than through external conduit, repair access to the Liebert
FS unit will be easier to facilitate if through-cabinet wiring is not installed.

5.1.1 System Module Description
The Liebert FS is a modular system composed as follows:
Control Panel
UPS Interconnection Kit
Power Conversion Module
Main Control Module
Flywheel Module
E-Stop (optional-special order)
Components are illustrated in Figure 35.
Control Panel
The Liebert FS uses a control panel as the primary means for an operator to interface with the sys-
tem.
UPS Interconnection Kit
The UPS Interconnection Kit is a module that enables the physical interconnection of the Liebert FS
and a UPS system. There are several versions that vary, depending on the UPS model.
The Liebert FS is delivered with a UPS interconnection kit consisting of a circuit breaker for connec-
tion of the positive and negative terminals coming from the UPS DC bus or from an external discon-
nect switch.
Power Conversion Module
The power conversion module is a bi-directional power electronics-based power converter capable of
sourcing or sinking power to and from the UPS DC bus.
While performing the Liebert FS’s backup power mission, the power conversion module converts
“variable frequency - variable voltage” AC power from the Liebert FS’ motor-generator and delivers
regulated DC voltage output to the UPS DC bus.
Conversely, for the Liebert FS’s needs in charging power, the power conversion module converts DC
power from the UPS DC bus into “variable frequency - variable voltage” AC power for the Liebert FS’
motor-generator.
Main Control Module
The Main Control Module provides the overall control of the Liebert FS as well as the specific control
for:
• Motor-generator
Active magnetic levitation hardware
Flywheel Module
The Flywheel Module houses several major components:
Motor-generator—synchronous reluctance technology
Rotating group—high-speed carbon composite flywheel, high-speed shaft and rotor of the motor-
generator
5-axis active magnetic levitation hardware
Molecular vacuum pump
E-Stop
The E-Stop is an Emergency Stop that allows the Liebert FS to disconnect from the UPS. The E-Stop
is a CE requirement for systems shipping to Europe (and other areas requiring the CE Mark). The
feature is available elsewhere as an option. Two choices are available for how the E-Stop is powered,
internally or externally. If E-Stop is activated, Liebert FS will enter a self-discharge and shutdown
mode.

Levitation Module [see 5.1.7 - Magnetic Levitation Module (MLM)]. The pre-charge resistor and
contactor which limit the inrush current into the DC bus capacitors. The six-pulse IGBT power con-
verter (IGBT Power Conversion Module (PCM) on page 36) which is controlled by the Power
Conversion Module Controller (Power Conversion Module on page 33) and which also monitors
and controls the operation of the entire system. These components are housed within the Power Con-
version Module. The Flywheel Module is shown as a cross-section to illustrate the rotating group and
the synchronous reluctance motor-generator.

5.1.4 User interfaces
Control Panel
The Liebert FS uses a Control Panel as the primary means for an operator to interface with the sys-
tem. Operating parameter values are displayed and updated in real time. Alarm states and system
notices are also displayed when they occur. User configurable system parameters are adjusted via the
Control Panel.
Data Collection Module (DCM)
An optional software and hardware package that reads data from the Liebert FS is available. The
data is stored and then can be transmitted through an RS-232 port, over a LAN (Local Area Network)
or over the Internet, enabling a diagnostic reporting capability.
Versatile Interface Board (VIB)
An optional software and hardware package is available that allows for remote monitoring and con-
trol; via isolated auxiliary contacts:

5.1.5 UPS Interconnection Kit
The UPS Interconnection Kit (IKIT) is a module of the Liebert FS that simplifies the interconnection
to a UPS system. There are different versions of the IKIT available that have been specifically devel-
oped for the UPS systems the Liebert FS can integrate with. The Liebert FS in the standard configu-
ration is delivered with an IKIT consisting of a fused Power Terminal Block for connection of the
Positive and Negative terminals coming from the UPS DC bus or from an external disconnect switch.

5.1.6 Power Conversion Module
Power Conversion Module Controller (PCMC)
The Power Conversion Module Controller is located within the Power Conversion Module. The PCMC
uses microprocessor-controlled logic to control the six pulse IGBT solid state switches and monitor the
active magnetic levitation system.
These operations are firmware controlled eliminating the need for manual adjustments. The logic
includes a self-test and diagnostic circuitry to identify any faults. Diagnostics are performed via a PC
through the RS232 communication port or through the control panel located on the front of the Lie-
bert FS.
IGBT Power Conversion Module (PCM)
The PCMC provides the overall control of the Liebert FS as well as the specific control for the syn-
chronous reluctance motor generator via the IGBT solid-state switches within the Power Conversion
Module.
The Power Conversion Module is a bi-directional system capable of sourcing or sinking power to and
from the stator. It converts variable frequency, variable voltage from the stator and delivers a con-
stant voltage DC output. Conversely, it converts DC power from the UPS System DC Bus to variable
frequency, variable voltage output to the stator as directed by the PCMC to increase the speed of the
synchronous reluctance motor-generator.
When delivering DC power, the output of the synchronous reluctance generator is rectified to DC by
passing the high frequency AC current through a solid-state power conversion device. The DC output
voltage of the Liebert FS has less than 2% Vrms ripple.
The voltage and frequency are adjusted using Pulse Width Modulation. The IGBT switches operate at
a frequency of 18 kHz to produce the smooth sinusoidal current waveform to and from the motor gen-
erator. This is smoothed out further using an inductive and capacitive filter.

5.1.7 Magnetic Levitation Module (MLM)
The Magnetic Levitation Module provides control of the active magnetic levitation hardware.
The Liebert FS has a unique active magnetic levitation system that fully levitates the flywheel-rotat-
ing group, allowing the flywheel to rotate without any physical contact. This has a number of advan-
tages over mechanical bearing systems:
Reduced drag- Mechanical bearings have a drag that is proportional to the square of the speed.
The levitation system developed by Liebert uses the same power regardless of speed.
Reliability and zero maintenance- The levitation system ensures there is no contact between the
rotating parts and the housing and therefore there are no components to wear out. This ensures
the unit will operate maintenance free for the life of the system.
The levitation system, works by measuring the displacement using a capacitive sensor, if the distance
needs to be adjusted; the current to the electromagnet is altered to change the displacement, each
axis is measured and controlled separately with its own capacitive sensor, electromagnet and feed-
back loop which, is controlled by the MLM. This is all done using analog control so it is very fast act-
ing and reliable. There are 5 different circuits working independently, these are: Radial: Upper X, Y;
Lower X, Y and Axial: Z Only
The principle of operation is the same in each case. The upper radial Y-axis is shown in Figure 37.
Figure 37 Schematic of the levitation system
Active Magnetic Levitation Hardware
The electromagnets and capacitive displacement sensors that provide the active magnetic levitation
are located within the flywheel module. See 5.1.7 - Magnetic Levitation Module (MLM) for a full

5.1.9 Rotor/Flywheel—Rotating Group
The flywheel is made of carbon/glass composite. This is mounted on a metal shaft with integral
motor-rotor and together these components form the rotating group. The rotating group is magneti-
cally levitated and centered so that it does not touch any other part while in normal operation.
Figure 39 Rotating group
5.1.10 Motor Generator
The rotor is positioned within the stator in such a way that the rotor and stator provide the
motor-generator function of the Liebert FS. The stator is liquid cooled and operates within a housing
in which air has been evacuated. Together the stator and rotor operate as a synchronous reluctance
motor-generator produces enough power for the system to supply its own internal demand and to sup-
ply to the output DC bus up to the rated power. The illustration in Figure 40 shows the four poles of
the synchronous reluctance machine.

5.1.11 Vacuum System
During manufacture, the vacuum chambers are evacuated and baked to remove water vapor. The vac-
uum system is then permanently sealed off to prevent any air entering the system and to remove the
possibility of accidental loss of vacuum. The Liebert FS does not require an external vacuum pump to
maintain a suitable vacuum level; the vacuum system instead relies on absorbers to maintain a rough
vacuum within the upper chamber. A zero-maintenance molecular drag pump acts with the flywheel
shaft to maintain a high-vacuum in the lower chamber, as shown in Figure 41. Vacuum levels of
much less than 100 microTorr (10-7 atmosphere) are maintained in the lower chamber. The absorber
material only needs to be recharged or changed, once every 15 years.

5.1.12 Flywheel Sensors
Speed
The speed detection system uses an infrared emitter and a sensor to detect the rotation of the shaft. A
hole drilled through the shaft allows light to pass and is detected on the opposite side by an infrared
detector. This signal is used to detect the rotor angle, the speed and any over speed condition. The
pulsed signal passes into the 6711 DSP to be converted into a speed signal. This is then passed to the
2812 DSP. The 2812 checks for over-speed and shuts down the power electronics if this occurs. If
either of the processors lock-up, the rotor will slow down, this guarantees that on over-speed cannot
occur.
Temperature
The stator and rotor temperature detectors are thermocouples and are both conditioned in a similar
way. The stator sensor is a Type J thermocouple potted into the stator windings. The rotor sensor is a
non-contact type sensor that detects the temperature of the rotor surface and gives an output in a
Type J thermocouple format.

5.1.13 System Safety
Every composite flywheel is inspected, spin balanced and tested to 110% over-speed in accordance
with NEMA guidelines. A patented dual-wall safety system ensures that in the unlikely event a fly-
wheel were to separate during operation, the inner housing would retain the carbon fiber. As the car-
bon fiber separates, it will expand and transfer its torque to the inner housing. The inner housing is
then allowed to rotate inside the outer housing. The cooling fluid in the outer housing, which sur-
rounds the inner housing acts as a dynamic brake. The stored energy is released in a controlled man-
ner as the flywheel / inner housing comes to a rest. The outer housing holds the entire safety system
and acts as a reservoir for the cooling fluid
The Liebert FS has been previously tested under the following fault conditions with no adverse safety
effects:
Motor-generator AC short circuit
DC short circuit
Power Conversion Module failure
Magnetic Levitation System failure
Composite rotor failure

5.1.15 Ventilation and Cooling
The Liebert FS stator and power electronics are liquid cooled with a liquid-to-air radiator. The radia-
tor within the Liebert FS package is designed for natural and forced air-cooling. Air inlets are pro-
vided from the bottom front of the Liebert FS enclosure. Air exhaust is from the top of the unit. Air
filters are provided as an option. A minimum 12" clearance overhead is required for the exhaust air-
flow.
The Liebert FS was designed with reliability in mind, the radiator is positioned to take advantage of
natural cooling and forced-air is only used when there is an elevated temperature. This also applies to
the circulating pump for the coolant, which is a highly reliable magnetically coupled centrifugal pump
that is powered with a brushless DC motor. This pump operates only when there is an elevated tem-
perature within the stator or the PCM, this extends the life of the pump to the point that it will con-
tinue to operate over the life of the unit.
5.2 List of System User-Configurable Parameters
In order to support a wide set of UPS integrations, the Liebert FS can be configured using the follow-
ing operating parameters: See 6.0 - Operation for more information on these parameters and
instructions on system setup and entering parameters to system.
Charge Voltage (Vcharge)
Vcharge is the voltage threshold above which the Liebert FS begins to charge/recharge.
Vcharge must be set at least 10VDC greater than Vreg.
Range: 360-600VDC
Default setting: 530VDC
Regulation Voltage (Vreg)
Vreg is the voltage setpoint at which the Liebert FS will regulate the DC bus voltage in Discharge
Mode

Default setting: 520VDC
Maximum Charge Current (Max Charge Current)
Max Charge Current is the Maximum Current the Liebert FS is allowed to draw from the UPS
DC bus.
Range—1-50A (typical operation requires a minimum of 3A or 5A)
Default setting—20 A
Charge Conductance (Charge Amps/Volts)
Charge amps/volts is used to set the Liebert FS charging current drawn from the UPS DC bus based
upon how much the UPS DC bus voltage is above Vcharge and so without exceeding the Max Charge
Current.

5.3 Modes of Operation
The Liebert FS consists of a variety of operational modes. Each mode is based on a set of programmed
conditions. The Control Panel indicates the current mode and the status of that mode. Function keys
are enabled or disabled depending on the mode and status.
The Liebert FS modes are:
• OFF
• STANDBY
• STARTUP
• CHARGE
• READY
• DISCHARGE
• SHUTDOWN
• COAST
• FAULT
The Liebert FS is programmed to operate in a variety of conditional modes. The modes and status for
each mode will be indicated on the control panel. The Liebert FS is set up to transition through the
various modes with no or minimal user intervention.
NOTE
Programming of Regulation Voltage (Vreg) Delta User Configurable Parameters
During a discharge the regulation voltage (Vreg) can be adjusted by setting the three
parameter set points described above; Vreg Delta 1, the Transition State of Charge (T SOC)
and Vreg Delta 2. (For more information on programming these parameters from the
Control Panel see 6.4.1 - Screen Tree Menu Functions)
The Liebert FS allows for programming two different discharge slopes (Vreg Delta1 and
Vreg Delta2) and enabling a soft “handcuff” or transition before end of discharge.
(Ex: if T SOC = 20 then transition from Vreg Delta 1 to Vreg Delta 2 will take place when
80%, (Vreg TSOC), of the stored energy has been discharged, see Figure 45).
Vreg Delta1 is used to program an initial slope from beginning of discharge to Vreg TSOC
over which the regulated voltage value will decrease and at which point a transition will
automatically occur to the secondary slope to 0% SOC at the Vreg Delta2 setpoint.

5.3.1 OFF Mode
When the Liebert FS is initially powered on, it enters the OFF mode and magnetically levitates its
rotating group. A manual user command will make the system transition from OFF mode to STAR-
TUP mode if all startup conditions are met.
The Liebert FS also will enter OFF mode at the end of a shutdown and will transition automatically
from SHUTDOWN mode to OFF mode.
5.3.2 STANDBY Mode
In STANDBY Mode, the Liebert FS will be ready for Startup but be in a STANDBY Mode waiting for
user initiation of STARTUP Mode (State of Charge = 0%). By pressing the STARTUP button “F1” at
that point the Liebert FS will automatically transition into STARTUP Mode.
Figure 46 STANDBY mode diagram
The Liebert FS will be in STANDBY Mode as long as:
Liebert FS’s SOC is less than 0%; and
UPS DC Bus Voltage = Vcharge
STARTUP has not been initiated
5.3.3 STARTUP Mode
In STARTUP mode, the Liebert FS will charge (increase flywheel speed) up to the minimum operat-
ing speed (State of Charge = 0%). At that point the Liebert FS will automatically transition into
CHARGE mode.
Figure 47 Startup mode diagram
The Liebert FS will be in STARTUP mode as long as:
Liebert FS’s SOC is less than 0% and
UPS DC Bus Voltage Vcharge.
In case the UPS DC bus voltage drops below Vcharge while in STARTUP mode, the Liebert FS will
transition automatically into COAST mode. As soon as the UPS DC bus voltage rises above Vcharge,
the Liebert FS automatically exits COAST mode and resumes STARTUP mode.
NOTE
Startup conditions are:

5.3.4 CHARGE Mode
To charge the Liebert FS, the Liebert FS will draw power from the UPS DC bus to accelerate the fly-
wheel (as long as the UPS DC bus voltage is higher than Vcharge). In this mode, the Liebert FS State
of Charge (SOC) will progressively increase from 0% to 100%.
Figure 48 CHARGE mode diagram
The Liebert FS will be in CHARGE mode as long as:
Liebert FS’s SOC is between 0% and 100% and
UPS DC Bus Voltage Vcharge.
5.3.5 READY Mode
When the SOC reaches 100%, the unit will automatically transition into the READY mode. This is the
mode in which the Liebert FS will spend most of its operating time. In this mode, the Liebert FS
maintains its State Of Charge greater than 99.5%. The Liebert FS’s SOC will be allowed to drift down
to SOC = 99.5%, at which point it will transition back into CHARGE mode and charge back up to
READY mode and SOC = 100%. During normal operation, the Liebert FS will continue to automati-
cally transition between the READY and CHARGE modes to maintain a SOC between 99.5 and 100%
until either a DISCHARGE or SHUTDOWN is initiated.
Figure 49 READY mode diagram
The Liebert FS will be in READY mode as long as:
Liebert FS’s SOC is between 99.5% and 100% and

5.3.6 DISCHARGE Mode
Starting from either CHARGE or READY mode, the Liebert FS will enter the DISCHARGE mode if
the UPS DC Bus Voltage goes below Vcharge. In DISCHARGE mode, the Liebert FS will regulate the
DC bus at Vreg.
Figure 50 DISCHARGE mode diagram
The Liebert FS will be in DISCHARGE mode as long as:
UPS DC Bus Voltage < Vcharge and
Liebert FS’s SOC is more than 0%.
The Liebert FS will leave the DISCHARGE mode and transition into CHARGE mode if the UPS DC
bus recovers (UPS DC Bus Voltage = Vcharge) before the Liebert FS’s SOC reaches 0%. In case the
UPS DC bus doesn’t recover before the Liebert FS’s SOC reaches 0%, the Liebert FS will transition
into SHUTDOWN mode.
5.3.7 SHUTDOWN Mode
In SHUTDOWN mode, the flywheel will actively spin down.
There are two ways the Liebert FS can transition into SHUTDOWN mode, by a complete discharge
and by a user command.
Following a Liebert FS Discharge Down to SOC = 0%
This is the most common SHUTDOWN process. This occurs when the Liebert FS’s SOC drops below
0% and the UPS System DC Bus voltage is less than Vcharge. If the Liebert FS entered the SHUT-
DOWN mode after leaving DISCHARGE mode, the Liebert FS will automatically transition into
STARTUP mode provided the UPS System DC Bus voltage returns to a value greater than Vcharge
(i.e., when the electric grid returns or the standby generator supplies power to the UPS).

Following a User Command
In any mode, except OFF mode, the user may command the Liebert FS to transition in SHUTDOWN.
While in SHUTDOWN mode, the user will still be able to command the Liebert FS to transition into
CHARGE mode (if SOC > 0%) or STARTUP mode (if SOC < 0%), provided that the UPS System DC
bus voltage is greater than Vcharge.
Figure 52 SHUTDOWN mode diagram - user-initiated shutdown
5.3.8 COAST Mode
A transition into COAST mode can occur when the UPS System DC Bus voltage drops below Vcharge
while the Liebert FS is in STARTUP mode. While in COAST mode, the Liebert FS is in an idling con-
dition where it neither draws nor generates any power.
As soon as the UPS DC Bus Voltage rises above Vcharge, the Liebert FS will automatically exit
COAST mode and resume STARTUP mode.
After five minutes in COAST Mode, if the UPS DC Bus voltage has not risen above Vcharge, the
Liebert FS will automatically transition into SHUTDOWN Mode.
5.3.9 FAULT Mode
The Liebert FS includes self-test and diagnostic circuitry such that most systems malfunctions can be
identified. In case of a system malfunction, the Liebert FS will transition into FAULT mode.
While in FAULT mode, the Liebert FS is disabled—all power electronics are turned off. Most faults
are cleared automatically by the system without the need for user intervention. Some faults do
require user action to clear the fault or to notify Liebert Services. Refer to the 8.0 - Troubleshooting
for more information).
The Liebert FS is programmed to operate in a variety of conditional modes. The modes and status for
each mode will be indicated on the control panel. The Liebert FS is set up to transition through the
various modes with no or minimal user intervention. Figure 53 illustrates the various modes of oper-
ation.
NOTE
Depending on the nature of the fault, the Liebert FS may still be capable of supporting the UPS
DC bus. Refer to 8.0 - Troubleshooting for more information.

5.4 Maintenance and Reliability
The Liebert FS is designed to require minimal preventive servicing and maintenance. There are no
user serviceable parts in the Liebert FS. Please contact a Liebert-Certified Technician before attempt-
ing to remove or service any components of the system. No bearings maintenance or replacement is
required over the life of the Liebert FS under normal operation conditions. No vacuum pump mainte-
nance or replacement is required over the life of the Liebert FS under normal operation conditions.
The optional inlet air filter in the cabinet will need to be replaced when it is sufficiently dirty as to
reduce the flow of air into the cabinet. Ambient conditions at the installation site will determine the
frequency of replacement. The Liebert FS Flywheel Module is designed for fifteen-year service life
before first scheduled maintenance. At fifteen years, the vacuum absorbers should be replaced or
regenerated.
The reliability of the Liebert FS power electronics is consistent with UPS power electronics of compa-
rable energy levels. The mechanical assemblies are of higher life and reliability than other commer-
cially available flywheel systems due to the elimination of rolling element bearings and external
vacuum-pumping systems.

6.3 Security Access
6.3.1 Security Levels
The Liebert FS software has two security levels: READ-ONLY and USER. Security levels restrict
access to system resources, such as EEPROM parameters, terminal commands and display panel
functions. From the Main Screen, Figure 55, the display can be locked at any time to prevent use of
Control Panel. Pressing F4 button under “LOCK” will prompt the user to enter a password to “LOCK”
the system. Once locked F4 will now read “UNLOCK” and pressing this will prompt you to enter the
Password to the system so that the user will be able to operate the Control Panel and adjust system
parameters and settings.
6.3.2 Password
READ-ONLY level has no password and it is default level at reset.
The USER level password is user-configurable and saved in EEPROM. The default USER level pass-
word is “1234”, and the password should be between 3 - 12 digits.
6.3.3 EPROM (System) Parameters
EEPROM (system) parameters can be accessed through display panel or terminal commands. They
can be read and written through terminal or display panel, but accessible parameters are limited by
security levels. The parameters for each level have different number range. Unused numbers are
reserved for future usage.
6.4 Menu Tree and Navigation
6.4.1 Screen Tree Menu Functions
The following diagram shows all of the screens accessible from the control panel and the path to bring
up these screens. The screens are used for configuring the Liebert FS for operation and accessing data
current and historical data on its performance. The screens are organized by five primary function
areas; Parameters, View, Security, About, and Tools. These are displayed on the Main Menu screen.
Some of the screens require User level or Service level passwords to access as shown in the legend
below. Refer to 6.3 - Security Access for more information on this subject.

6.4.2 Navigation and Operation of Control Panel
Navigation of the menu screens is simple and intuitive. From the Main Screen, also referred to as
“Home”, menu functions and screens can be accessed by using the function keys and the numeric key-
pad. The function keys, F1- F6, initiate certain system functions and Modes; STARTUP, SHUT-
DOWN and also perform certain menu screen functions; DONE, PREVIOUS, NEXT, and HOME. The
up and down arrows on the control panel enable the user to scroll up or down certain menus. The
numeric keypad can be used to enter values for system setup and the Enter and Backspace keys to
enter numbers or backspace to change entry. Pressing F6 or DONE completes the entry process.
Always double check by going back to the previous screen to verify the entry is complete and accurate.
To access the Main Menu press the F6 button below the “Menu” option in the lower right. When
pressed, the “Menu” key, will display the Main Menu screen as shown in Figure 58. From this screen
each of the submenus may be accessed, provided the user has security access where needed, refer to
Figure 57.
Each screen in the menu tree will show numbers in front of the subject if more information is avail-
able at the next menu level. Pressing the number for the subject using the numeric keypad will bring
up that screen. If the subject is preceded by a double arrow symbol (>>) instead of a number no fur-
ther information is available or the parameter may not be modified without security access.
At each screen and level in the menu tree, when finished accessing data or changing system parame-
ters, the user may select DONE using the function keys to move back to the prior screen in the menu
or when available press HOME, F5, to return to the Main Screen. On some screens such as in the His-
tory screens you will be able to access additional screens of data recorded by pressing NEXT, see
Figures 70 and 71.
Figure 58 User level main menu screen
6.4.3 System Setup and Parameter Access
Setting up the Liebert FS:
In order to operate the system the system parameters must be configured for the application. The sys-
tem parameters or “EEPROM” parameters can be accessed by first pressing MENU, F6, and the num-
ber one (1) button on the Control Panel keypad for the PARAMETERS screen. Liebert FS software
has two kinds of access screen according to the security level.
In READ-ONLY mode, seven basic parameters can be monitored. Modifying the parameters in this
mode is not allowed. In this mode the parameters will have double arrow symbols to the left of the
parameters.

6.5.5 Regular Startup Procedure
6.5.6 Inspection Before Regular Startup
The following verifications must be done before performing a regular startup of the Liebert FS (see
6.5.7 - Starting up the System):
1. Make sure the Liebert FS is properly secured to the floor with the Liebert-provided mounting kit
and in compliance with the floor mounting instructions in 4.1 - Cabinet Floor Mounting.
2. Check for coolant leaks in and around the Liebert FS unit.
3. Ensure that Liebert FS cabinet panels are in place on the cabinet and that no tools have been left
in the cabinet
4. Ensure that the Liebert FS Main circuit-breaker (optional) or the customer-provided external DC
disconnect switch is open
5. Verify that the AC Auxiliary Backup Power is connected and powered by closing fused disconnect
or wall disconnect and check if the Control Panel is ON and with no warning or fault messages
displayed.
The Liebert FS may now be started up.
6.5.7 Starting up the System
Powering Up the Liebert FS
Once AC voltage is applied to the Liebert FS, the Liebert FS Control Panel will boot up. Its screen will
begin to illuminate after 5 to 10 seconds and then display a series of boot up protocols.
Booting Up
1. It takes about 25 seconds to load and initialize the primary application software at STARTUP or
after reset.
2. Title block and firmware versions will be displayed (see Figure 82). If the secondary DSP does
not boot up properly, versions for the secondary DSP may be corrupted or zero.
3. EEPROM checksum will be calculated and compared with the stored value. EEPROM checksum
fault will be generated if they do not match. For this case, default values are loaded for
parameters in RAM. However, EEPROM contents are not changed.
4. Response from secondary DSP will be checked. “INTERPROCESSOR COMM FAULT” will be
generated if the communication is not set up properly. The controller will reset itself for this case.
5. Previous operation command (STARTUP or SHUTDOWN) will be retrieved to determine the
current operation mode.
6. Option status is checked. Current available options are VIB and DCM.
!CAUTION
The Initial System Startup shall be performed ONLY under the supervision of a Liebert
technician to ensure proper system operation. Failure to abide by instructions provided herein
may void your warranty.
NOTE
A regular startup is any startup after the Initial System Startup.
!CAUTION
The following procedure assumes that the Initial System Startup has been performed under
the supervision of a Liebert technician.
!CAUTION
Do not attempt to run the system unless the system loads valid parameters.

Validation of Control Parameters Setup
1. Once the Control Panel has successfully booted up, the Control Panel will display the Main
Screen (see Figure 55).
2. Verify the Control Parameters values are correct. (Consult Table 9 and the relevant UPS
Interconnection Kit Handbook for choosing the proper Control Parameters values).
3. Adjust the Control Parameters values if necessary (see 6.4.1 - Screen Tree Menu Functions).
for instruction on how to change the values of the Control Parameters) then press “F6 DONE”.
Initiating Liebert FS Startup Sequence
1. Once sufficient DC voltage is applied to the UPS DC Bus, the Liebert FS will be able to transition
from the OFF Mode to Startup Mode, unless system was previously Shutdown by command.
The following action is conditional on the UPS interconnection kit that has been installed on your
Liebert FS:
Standard UPS Interconnection Kit (IKIT-STD)
The Standard UPS interconnection kit (IKIT-STD) includes a fused Power Terminal Block. It is
recommended for maintenance use to have an external disconnect switch installed between the
UPS and the Liebert FS.
Close the customer-provided external disconnect switch at the time indicated by the UPS startup
procedure.
Optional UPS Interconnection Kit
Open the Liebert FS cabinet front door and close the Liebert FS main circuit-breaker at the time
indicated by the UPS startup procedure. Close the cabinet door.
2. The Control Panel will then show the Main screen (see Figure 55). The System Mode should read
“OFF”. The Liebert FS will actively check for presence of sufficient voltage to allow system
startup.
3. As soon as the UPS DC bus voltage is greater than Vcharge, the System Status will change from
“OFF” to “STAND BY”. The “F1 STARTUP” key will then be enabled.
4. Press the “F1 STARTUP” key.
Liebert FS Startup Sequence
As soon as the “F1 STARTUP” key is pressed, the Liebert FS will launch its startup sequence. This
will progressively lead the Liebert FS through the different Modes of Operation (STAND BY, STAR-
TUP, CHARGE) to eventually reach a ready state of idling (READY Mode) once it is completely
charged up. The automatic transition between modes is described in 5.2 - List of System User-Con-
figurable Parameters.
6.6 Shutdown Procedure
There are two ways the Liebert FS may enter a Shutdown sequence: either a) following a Liebert FS
discharge down to SOC = 0%; or b) following a user-initiated command.
In any Mode, except OFF Mode, the user may command the Liebert FS to transition in SHUTDOWN
Mode by pressing the “F2 SHUTDOWN” key. This action is recommended for normal shutdown of the
system. In this condition, the Liebert FS will not discharge to support an outage. You will be asked to
confirm “Yes” or “No” to SHUTDOWN. Press “Yes” to confirm shutdown and put system in SHUT-
DOWN mode.
For more information concerning the SHUTDOWN Mode, please refer to 5.2 - List of System User-
Configurable Parameters.
NOTE
Startup procedures will vary for each UPS model.
NOTE
Optional UPS interconnection kits include circuit-breakers then referred to as “Liebert FS
Main circuit-breaker”.

7.0 MAINTENANCE
7.1 Safety Precautions
Observe all safety precautions in this manual, paying particular attention to Important Safety
Instructions on page 1.
ONLY qualified service personnel should perform maintenance on the Liebert FS.
Observe all of the warnings below before performing any maintenance on the Liebert FS and associ-
ated equipment.
!WARNING
Before performing preventive maintenance tasks, the Liebert FS must be de-energized and
electrically isolated (both AC and DC connections to the Liebert FS must be electrically
disconnected).
!CAUTION
Always identify connecting wiring prior to disconnecting any wiring.
Do not substitute parts except as authorized by Liebert Corporation.
Keep Liebert FS cabinets free of foreign materials such as solder, wire cuttings, etc.
Contact Liebert Services if you are not sure of the procedures to follow or if you are not
familiar with the circuitry.
!WARNING
Extreme caution is required when performing maintenance.
Be constantly aware that the Liebert FS contains high DC as well as AC voltages. With input
power off and the battery disconnected, high voltage at filter capacitors and power circuits
should be discharged within 30 seconds. However, if a power circuit failure has occurred, you
should assume that high voltage may still exist after shutdown. Check with a voltmeter
before making contact.
Check for voltage with both AC and DC voltmeters prior to making contact.
When the Liebert FS is under power, both the operator and any test equipment must be
isolated from direct contact with earth ground and the chassis frame by using rubber mats.
Some components within the cabinet are not connected to chassis ground.
Any contact between floating circuits and the chassis is a lethal shock hazard. Use differential
oscilloscopes when measuring a floating circuit. The differential input should have at least
800 VRMS common mode input rating and a common mode rejection ratio of at least 80dB.
Exercise caution that the test instrument exterior does not make contact, either physically or
electrically, with earth ground.
In case of fire involving electrical equipment, use only carbon dioxide fire extinguishers or
others approved for use in fighting electrical fires.

7.2 Liebert Services
Startup, maintenance and training programs for the Liebert FS are available through your Liebert
sales representative.
Professional Startup
Liebert FS Startup—Liebert’s customer engineers perform a thorough, non-powered inspection of
the units and will then conduct a complete electrical checkout that includes calibrating all compo-
nents to published specifications. Customer operation training will be conducted during startup.
Load bank testing and full site acceptance testing are additional services that can be performed dur-
ing a Liebert FS startup. One preventive maintenance service call can be added to the initial
Liebert FS startup agreement.
Maintenance Agreements: The Signature Program
Liebert FS Service Agreements—Liebert Services has a variety of available maintenance agree-
ments, depending on specific site needs. Choose the level of support appropriate for each installation.
Mission-critical sites can have the standard parts-and-labor, around-the-clock coverage for their
Liebert FS, with or without scheduled preventive maintenance visits. Other sites can benefit from a
variety of money-saving options.
While the Liebert FS is designed to be maintenance-free, Liebert suggests at least one preventive
maintenance visit per year. This preventive maintenance work would normally be done in conjunction
with a service visit for another Liebert UPS product. The annual visit will require taking the
Liebert FS off-line for a thorough, nonpowered inspection. These visits are in addition to the general
housekeeping tasks (changing air filters, etc.) that can be performed by customer personnel.
Training
Customer training courses include the proper operation of the system, emergency procedures, preven-
tive maintenance and some corrective maintenance.
Warranties
Contact Liebert Services if you have any questions regarding the warranty on your Liebert FS.
7.3 Routine Maintenance
You are encouraged to become thoroughly familiar with the equipment, but at no time should you go
beyond the specific procedures in this manual while performing maintenance or correcting a malfunc-
tion. If you have any doubt as to what must be done, call Liebert Services at 1-800-LIEBERT for fur-
ther instructions.
The Liebert FS is designed for unattended operation, but does require some common-sense mainte-
nance:
Keep good records—Troubleshooting is easier if you have historical background
Keep it clean—Keep the Liebert FS free of dust and moisture
Keep it cool—The Liebert FS will reliably meet all performance specifications and design life at
temperatures up to 122°F (50°C)
Keep connections tight—Tighten all connections at installation and at least annually thereafter
(see torque requirements,Table 12)

7.4 Maintenance Schedule
The Liebert FS maintenance schedule consists of actions listed in Table 11.
7.5 Record Log
Set up a maintenance log to record scheduled checks and any abnormal conditions.
The log should have space for all metered parameter indications including phase readings, alarm
messages, mode of operation, air filter replacement date and observation notes.
A periodic walk-through inspection of the Liebert FS room is advised to check for visible and audible
indications of problems. Log the inspection, metered parameter indications and any discrepancies.
!WARNING
Any maintenance on the system should be delayed by at least 10 minutes after system is shut
down to be certain all electronics have discharged. Use appropriate safety precautions to
ensure unit is disconnected and de-energized.
!CAUTION
Unless specified otherwise, ONLY a Liebert-certified service technician should perform all
maintenance work. Failure to use a Liebert technician for maintenance actions, unless
specifically noted, may void your warranty.

PROD UC T
Maintenance
76
7.6 Optional Air Filters
The optional air filters must be inspected and serviced on a regular schedule. The period between
inspections will depend upon environmental conditions. Under normal conditions, the air filters will
require cleaning or replacement approximately every 12 months.
Abnormal or dusty conditions will require more-frequent cleaning and replacement of air filters
(sometimes as often as every two months). Inspect installations in new buildings more often, then
extend the inspection period as experience dictates.
7.7 Torque Requirements
All electrical connections must be tight. Table 12 provides the torque values for the connections in
the Liebert FS. Use these values unless the equipment is labeled otherwise.
7.8 Detecting Trouble
It is important that the operator check the instrument readings if abnormal equipment performance
is suspected. Any metered value that differs appreciably from normal could mean an impending mal-
function and should be investigated.
Items to check include:
Alarm messages indicate malfunction or impending malfunction. A daily check of the operator
control panel will help to provide an early detection of problems. Refer to Table 16 to interpret
alarm messages.
Tracing a problem to a particular section is facilitated by alarm messages and the metered
parameter indications. These are stored in the Status Reports and can be displayed at the opera-
tor control panel or at an optional terminal. A Liebert Services engineer will be familiar with test
points inside the unit.
!CAUTION
Be certain recyclable filter elements are dry before reinstalling them in the Liebert FS.

7.9 Reporting a Problem
If a problem occurs within the Liebert FS, review all alarm messages along with other pertinent data.
This information should be given by telephone to the Liebert service representative’s office nearest
you. This information can be downloaded to Liebert Services by using the optional modem. Contact
Liebert Services at 1-800-LIEBERT to report a problem or to request assistance.
7.10 Corrective Actions
For each alarm message on the operator control panel, you can find the recommended corrective
action in Table 16.
7.11 Recommended Test Equipment
Table 13 lists recommended test equipment and tools required to maintain, troubleshoot and repair
the Liebert FS. You may substitute instruments of equivalent range and accuracy.
All instruments should be calibrated and be within the current calibration cycle. Calibration data for
the instruments should be maintained in equipment-history files and the instruments labeled for
audit and verification.
7.12 Limited Life Components
Your Liebert FS has a design life well in excess of 15 years. Well-maintained units can continue to
provide economic benefits for 20 years or more. Long-life components are used in your Liebert FS
wherever practical and cost-effective.
However, due to current component material and manufacturing technology limitations, a few compo-
nents in your Liebert FS will wear out and require replacement in less than 10 years. The following
limited-life components are utilized in your Liebert FS. In order to prevent a wear-out failure of one of
these components affecting your critical load operations, it is recommended these components be peri-
odically inspected and replaced before their expected wear-out life. Individual users may have site-
specific requirements that differ from these typical life expectations.
Power capacitors are considered “failed” when their measured capacitance is –5% below their name-
plate rating.
In most cases, replacement components must exactly match the original component specifications and
are not readily available from third-party component distributors. For assistance with your specific
component specifications, replacement component selection and sourcing, call 1-800-Liebert.
For customers using Liebert Services’ Preventive Maintenance Services, periodic inspection of these
components are part of this service as is recommending to customers replacement intervals to avoid
interruptions in critical load operations.

8.0 TROUBLESHOOTING
8.1 General
The Liebert FS is capable of detecting conditions outside of normal operating parameters and provid-
ing notice at the Control Panel. This data is recorded as either Warnings or Faults and can be viewed
in the software menu tree at the screen location MENU>VIEW>. These Warnings and Faults can also
be communicated by the Versatile Interface Board (VIB), if this option has been installed, to an exter-
nal device or system; (see Appendix C.0 - Versatile Interface Board). This data will also be
recorded in the Data Collection Module option if this has been selected. Please see Appendix B.0 -
Data Collection Module for instructions on how to access this data via the DCM.
Any Warnings and Faults that may occur will be displayed on the Main screen of the Control Panel.
The Liebert FS’ Warnings and Faults tables (see Tables 15 and 16), describe these Warnings, mean-
ings and possible causes. The operator action required or automatic system function that will result is
explained.
In addition to the information displayed on the Main screen, other system information that can be
used for troubleshooting is available and can be accessed from the Control Panel. From the Main
screen the Menu screen can be selected by pressing (F6) on the Control Panel located below MENU.

tem that may adversely affect it.
8.2 Warnings
A Warning is an indication of an abnormal system condition significant enough to warrant being
annunciated and logged. Warning conditions may indicate that a system parameter is out of its nor-
mal operating range, or may signal an external problem. A Warning indication is for information only
and does not require any operator intervention for continued operation of the unit. While in Warning
condition, normal operation of the unit will continue unimpeded. A warning can indicate an operating
condition that warrants observation and may require preventative maintenance.
Figure 93 Warning screen
The Warning condition is indicated by the System Status field displaying “WARNING” in the Control
Panel window (see Figure 93). If one Warning is present, the Warning Label (see Table 15.) will be
displayed.
While the Warning condition exists, and if more than one Warning is present, F5 the “More Info” key
will be enabled in the Control Panel window. If pressed, the separate Warning Labels will be dis-
played in the Control Panel window.
Any of eight warnings could occur while the Liebert FS is operating. Warnings give advance alert of
potential problems and schedule service and preventive maintenance. These can be monitored and
investigated through the use of data from the Control Panel and system tests.

8.3 Faults
A Fault is defined as an undesirable system operating condition that could cause further damage to
the system or potentially drop the load. Once detected, Faults may trigger an appropriate emergency
action such as shutting the unit down. Most Fault conditions are automatically taken care of by the
Liebert FS control system and require no Operator intervention. A few Fault conditions may be
resolved only through operator intervention or service by a Liebert technician.
A Fault condition must be valid for a certain amount of time before it is recognized as an active Fault.
This prevents spurious signals from causing false Fault detection and unnecessary state changes.
Figure 93 shows the appearance of an active Fault on the main screen.
Figure 94 Fault screen descriptions
While in Fault condition, normal operation of the unit is suspended, the operation of the Power Con-
version Module is paused, and the unit transitions into FAULT Mode, where it waits for one of the fol-
lowing to occur:
1. The condition to clear the fault [AUTO CLEAR]
2. The unit to automatically transition in SHUTDOWN Mode [AUTO SHUTDOWN]
3. Operator action [OPERATOR CLEAR].
The Fault condition is indicated by the System Mode displaying “FAULT” in the Control Panel win-
dow.
If there are multiple Fault conditions present, the F5 “More Info” key will be enabled in the Control
Panel window. If pressed, information related to the specific Faults will be displayed in the Control
Panel window (see Figures 54 through 56). If there are multiple faults they will both be displayed by
pressing the F5 “MORE” button.
In many cases, when FAULT Mode is entered, the Fault may be cleared by pressing the F3 “CLEAR
FAULT” button on the Control Panel or utilizing the VIB option - if enabled - to send a “CLEAR
FAULT” signal to the system. In order to “CLEAR FAULT” the operator must be in proper security
access level; User or above. Table 16 describes the fault labels, meanings and possible causes for the

Appendix A.5.7 Liebert FS Configuration – Multiple Liebert FS Units
Liebert FS Software Control Parameters must be reset when multiple Liebert FS units are connected
in parallel on the DC bus of a Liebert HiPulse™ UPS system.
Instructions to set these parameters on the Liebert FS are found in 6.5.3 - Control Parameters
Setup at Initial System Startup.
Multiple Liebert FS Parallel Operation—Regular Configuration
Liebert FS Software Control Parameters must be reset when multiple Liebert FS units are connected
in parallel on the DC bus of a Liebert HiPulse™ UPS system for proper operation with longer run
times or higher backup power requirements. The Liebert FS units will contribute all together at the
same time to the task of supporting the UPS DC bus.
Instructions on setting these parameters on the Liebert FS are found in 6.5.3 - Control Parameters
Setup at Initial System Startup.

Appendix B.1 General Information
Appendix B.1.1 Overview
The Data Collection Module (DCM) is designed to provide real-time data monitoring and data storage
for the Liebert FS. The DCM collects data on virtually every event that occurs in the Liebert FS. Data
such as speed, temperature and voltage are just a few of the data points that the DCM will be collect-
ing and storing on its internal memory card. The DCM has an HTML interface, which means any
Internet browser, such as Internet Explorer or Netscape, is all that is required to access the
Liebert FS data.
Appendix B.1.2 Features
The DCM comes equipped with four (4) RS-232 communication ports and a 10/100 Base-T RJ-45 port.
The DCM runs on the Linux operating system, which resides on the internal compact flash memory
card. Dynamic Host Configuration Protocol (DHCP) has been enabled on the DCM to allow easy inte-
gration with an existing network.
