1.3 Environmental Considerations
1.3.1 UPS Room
The UPS module is intended for indoor installation and should be located in a cool, dry, clean-air
environment with adequate ventilation to keep the ambient temperature within the specified
operating range (see Environmental Parameters in Table 8).
The Liebert eXL UPS is cooled with the aid of internal fans. To permit air to enter and exit and
prevent overheating or malfunctioning, do not cover the ventilation openings.
The Liebert eXL UPS is equipped with air filters located behind the front doors. A schedule for
inspection of the air filters is required. The period between inspections will depend upon
environmental conditions.
When bottom entry is used, the conduit plate must be installed.
1.3.2 Storage
Should the equipment not be installed immediately, it must be stored in a room for protection against
excessive humidity and/or heat sources (see Environmental Parameters in Table 8).
1.4 Positioning
The cabinet is structurally designed to handle lifting from the base.
Access to the power terminals, auxiliary terminal blocks and power switches is from the front.
The door can be opened to give access to the power connection bars, auxiliary terminal blocks and
power isolators. Front door can be opened to 90 degrees, and interior doors can be removed for more
flexibility in installations.
1.4.1 Moving the Cabinets
The route to be travelled between the point of arrival and the unit’s position must be planned to make
sure that all passages are wide enough for the unit and that floors are capable of supporting its
weight (for instance, check that doorways, lifts, ramps, etc. are adequate and that there are no
impassable corners or changes in the level of corridors).
Ensure that the UPS weight is within the designated surface weight loading (lb/in2) of any handling
equipment. For weight details, see Table 8.
The UPS can be handled with a forklift or similar equipment. Ensure any lifting equipment used in
moving the UPS cabinet has sufficient lifting capacity. When moving the unit by forklift, care must be
taken to protect the panels. Do not exceed a 15-degree tilt with the forklift. Bottom structure will
support the unit only if the forks are completely beneath the unit.
Handling with straps is not authorized.
NOTE
The UPS is suitable for mounting on concrete or other non-combustible surface only.
NOTE
The UPS must be placed on a non-combustible surface suitable to support the weight of the
unit.
!
WARNING
Risk of heavy unit falling over. Improper handling can cause equipment damage, injury or
death.
Because the weight distribution in the cabinet is uneven, use extreme care while handling
and transporting. Take extreme care when handling UPS cabinets to avoid equipment
damage or injury to personnel.

1.4.2 Clearances
The Liebert eXL has no ventilation grilles at either side or at the rear of the UPS. Clearance around
the front of the equipment should be sufficient to permit free passage of personnel with the doors fully
opened. It is important to leave a distance of 24in. (610mm) between the top of the UPS and any
overhead obstacles to allow the module to be serviced and to permit adequate circulation of air coming
out of the unit.
1.4.3 Raised-Floor Installations
If the equipment is to be located on a raised floor, it should be mounted on a pedestal suitably
designed to accept the equipment point loading. Refer to Figure 7 to design this pedestal.
1.4.4 Kick Plate Installation
If the unit is to be installed in a position that does not permit access to rear kick plates, then the kick
plates should be installed before the unit is placed in its final position.
1.5 System Composition
A UPS system can include a number of equipment cabinets, depending on the individual system
design requirements: e.g., UPS cabinet, battery cabinet, maintenance bypass cabinet. In general, all
the cabinets used in a particular installation are of the same height. Refer to the drawings provided in
4.0 - Installation Drawings for the positioning of the cabinets as shown in Figure 1.
1.6 Cable Entry
Cables can enter the UPS cabinet from bottom or top into the Input/Output (I/O) of the unit; see the
figures in 4.0 - Installation Drawings.
1.7 Cable routing
Per NEC 300.20 (NEC 2014 or equivalent), all phase conductors and ground conductors must be
grouped together when they are installed in ferrous enclosures or go through ferrous material. This is
to avoid heating from induction currents.

2.0 UPS ELECTRICAL INSTALLATION
This chapter provides guidelines for qualified installers who must have knowledge of local wiring
practices pertaining to the equipment to be installed.
2.1 External Protective Devices
For safety, circuit breakers must be installed in the input AC supply and external battery system.
Given that every installation has its own characteristics, this section provides guidelines for qualified
installation personnel with knowledge of operating practices, regulatory standards and the
equipment to be installed.
External overcurrent protection must be provided. See Figures 18,19 and 20 for overload capacity.
2.2 Power Cables
The UPS requires both power and control cabling. All control cables, whether shielded or not, should
be run separately from the power cables in metal conduits or metal ducts that are electrically bonded
to the metalwork of the cabinets to which they are connected.
The cable design must comply with the voltages and currents in Tables 9 through 12, follow local
wiring practices and take into consideration the environmental conditions (temperature and physical
support media), room temperature and conditions of installation of the cable and system’s overload
capacity (see 5.0 - Specifications).
!
WARNING
Risk of electrical shock. Can cause injury or death.
The UPS contains high DC as well as AC voltages. Check for voltage with both AC and DC
voltmeters before working within the UPS.
Only properly trained and qualified personnel wearing appropriate safety headgear, gloves,
shoes and glasses should be involved in installing the UPS or preparing the UPS for
installation.
!
AVERTISSEMENT
Risque de décharge électrique pouvant causer des blessures graves, voire mortelles.
Le système ASC contient des tensions c.c. et c.a. élevées. Vérifiez les tensions au moyen de
voltmètres c.a. et c.c. avant d’utiliser le système ASC.
Seuls des employés qualifiés et dûment formés portant un casque, des gants, des chaussures
et des lunettes de sécurité adéquats doivent se charger d’installer le système ASC ou de le
préparer pour l’installation.
!
WARNING
Risk of electrical shock. Can cause injury or death.
Before cabling the UPS, ensure that you are aware of the location and operation of the
external isolators that connect the UPS input/bypass supply to the power distribution panel.
Check that these supplies are electrically isolated, and post any necessary warning signs to
prevent their inadvertent operation.

When sizing battery cables, a maximum voltage drop of 2VDC is permissible at the current ratings
given in Table 12.
The following are guidelines only and are superseded by local regulations and codes of practice where
applicable:
• The grounding conductor should be sized according to the fault rating, cable lengths, type of
protection, etc. The grounding cable connecting the UPS to the main ground system must follow
the most direct route possible.
• Consideration should be given to the use of paralleled smaller cables for heavy currents, as this
can ease installation considerably.
• AC and DC cables must be run in conduits according to local codes, national codes and standard
best practices. This will prevent creation of excess EMI fields.
2.3 Sizing the Input Breaker Feeding a Liebert eXL UPS
Nominal input current (considered continuous) is based on full-rated output load. Maximum current
includes nominal input current and maximum battery recharge current (considered noncontinuous).
Continuous and noncontinuous current are defined in the NEC.
Maximum input current is controlled by the current limit setting, which is adjustable. Values shown
are for default current limit of 125%. If a smaller input feed breaker is used, the input current limit
can be adjusted; see your Emerson representative for more information. The input current limit
should not be set less than 105% of the current needed to support the inverter at full load for normal
operation. This results in sufficient power to recharge the battery in a reasonable time and to operate
over the published input voltage range.
2.3.1 Power Cable Connection Procedure
The rectifier input, bypass, output and battery power cables (all require lug-type terminations) are
connected to busbars in the I/O sections (refer to 4.0 - Installation Drawings).
Equipment Ground
The equipment ground busbars are in the I/O sections (refer to 4.0 - Installation Drawings). The
grounding conductor must be connected to the ground busbar and bonded to each cabinet in the
system.
All cabinets and cabling should be grounded in accordance with local regulations.
NOTE
Proper grounding reduces problems in systems caused by electromagnetic interference.
!
WARNING
Failure to follow adequate grounding procedures can result in electric shock hazard to
personnel, or the risk of fire, should a ground fault occur.
All operations described in this section must be performed by properly trained and qualified
electricians or technical personnel. If any difficulties are encountered, contact Emerson
Network Power. See the back page of this manual for contact information.
!
AVERTISSEMENT
Le non-respect des procédures de mise à la terre peut entraîner des risques d’électrocution du
personnel, ou des risques d’incendie en cas de défectuosité de la mise à la terre.
Toutes les opérations décrites dans cette section ne doivent être effectuées que par des
électriciens ou des techniciens professionnels dûment formés et qualifiés . En cas de
difficultés, communiquez avec Emerson Network Power. Pour obtenir les renseignements de
contact, consultez la dernière page de ce manuel.

2.5 Grounding
2.5.1 Three-Wire Input connections
This module must NOT be used when single-phase loads are directly connected to the UPS. Note that
whenever the UPS module transfers to or from bypass, two AC sources (UPS output and bypass) are
briefly connected together and circulating current must flow. In this configuration, the current flows
through the ground path and may trip ground fault interrupters (GFI’s), distorting the output voltage
waveform. Proper adjustment of GFI’s is necessary to avoid unwanted tripping. The time delay
should be set to at least 0.2 seconds to prevent tripping when the UPS performs a transfer or
retransfer operation.
NOTICE
Failure to set the ground fault interrupters properly could cause loss of power to the critical
load.
2.5.2 High Resistance Grounding (see attached document)
The Liebert eXL is not compatible with high-resistance ground systems. See your local Emerson
representative for details.
2.5.3 Preferred Grounding Configuration, Battery Systems
Open-rack battery systems, depending on local code requirements and customer preference, are
normally:
• Floating (ungrounded) OR
• Center-tapped and floating
Battery cabinet systems must be connected as floating (ungrounded) systems.
Center-tapped or grounded battery systems are not possible with battery cabinet systems.
Whether the battery system is open-rack or cabinet, the metal rack parts or cabinet must be grounded
to the UPS module ground bus.

1. Recommended cable sizes are 167°F (75°C) (THW) wire at 86°F (30°C) ambient. Unless otherwise noted, use copper or
aluminum conductors suitable for at least 75°C.
2. Recommended cables and conduits are based on breaker trip setting adjusted to the maximum rated current for the rectifier
input and the nominal current for the bypass and output listed in Tables 9 through 12.
3. Conduit size is based on FMC type conduit.
4. Emerson recommends that the site planner choose the appropriate cable type based on the particular installation
requirements.
