Safety Symbols used in this manual
WARNING!

Indicates a hazard which, if not avoided, could result in injury or death.

CAUTION!

Indicates a hazard which, if not avoided, could result in damage to the
product or other property.

NOTICE!

Read and pay attention to this important information.

WARNING!
This UPS unit contains hazardous AC and DC voltages. Only qualified electricians should install
the UPS, AC line and external batteries, and must be familiar with batteries and battery
installation.
Before installing, maintaining or servicing the UPS, shut off the UPS and disconnect all sources
of AC and DC power.
As the UPS has no built-in disconnection devices to switch off external AC and DC input power,
ensure that disconnection devices are provided as separate parts in connection with the
installation!
The installer must provide each external disconnecting device for this UPS system with labels
with the following text:
“Isolate the Uninterruptible Power Supply (UPS) as instructed in this guide before working on
circuit”
AC and/or DC voltage will always involve a potential risk of AC voltage at UPS output generated
from either batteries or mains. To avoid equipment damage or personal injury, always assume
that there may be voltage at UPS output.
This system is equipped with an auto-start function. If activated, the system may start without
warning. Refer to the “Programming” section of this guide for information on de-activation.
TEST BEFORE YOU TOUCH!
To reduce the risk of fire or electric shocks, install the UPS and external batteries in a
temperature and humidity controlled indoor area, free of conductive contaminants.
UPS batteries are high-current sources. Shorting battery terminals or DC terminals, DC busbars
can cause severe arcing, equipment damage and injury. A short circuit can cause a battery to
explode. Always wear protective clothing and eye protection and use insulated tools when
working on batteries.

CAUTION!
This unit contains components sensitive to electrostatic discharge (ESD). If you do not follow the
normal ESD procedures, you may cause severe damage to electronic components.

System Integration Interface

NOTICE!
Consistent use of designations (Q001, Q002, Q003, H002, H003) in diagrams simplifies
information exchange.
System Integration Interface (SII) is the control link between UPS and system main switches
as shown in above diagram. The purpose of the SII is to ensure correct operation of switches
without losing system output power.
Auxiliary contacts on the main switches transmit the SII board inputs. Lamps on Service
Bypass Panel and Battery Breaker Box/Battery Cabinet indicate “green light” for operation of
output switches.
SII board also integrates input facilities for emergency shut-down and temperature
compensation of charge voltage for external battery (use with battery monitor). “Battery
operation” and “Common fault” are two main SII board status relay signals.

Terminal Blocks: X003/X004 (Anxiliary Contacts)
When switching Q001, Q002, Q010, Battery Breaker 1 or Battery Breaker 2 from “ON or 1” to
“OFF or 0”, the anxiliary contact has to be open BEFORE the corresponding main contacts are
opened. When switching Q001, Q002, Q010, Battery Breaker 1 or Battery Breaker 2 the
opposite way from “OFF or 0” to “ON or 1”, the anxiliary contact has to close with a maximum
delay of 0.5 seconds from the time the corresponding main contacts are closed.
• This type of auxillary contact is called a “late make” contact. (This also means that it will
“break early” when activated in opposite direction.)
• This auxillary contact is also called “NORMALLY OPEN” (NO), because the auxillary
contact will be open when the main contacts are open.
• Please note that the above term “NORMALLY” has nothing to do with NORMAL UPS
OPERATION MODE.
When switching Q003 from “OFF or 0” to “ON or 1”, the anxiliary contact has to open BEFORE
the corresponding main contacts are closed. When switching Q003 the opposite way from “ON
or 1” to “OFF or 0”, the auxillary contact has to close with a maximum delay of 0.5 seconds from
the time when the corresponding main contacts are opened.
• This type of anxiliary contact is called an “early break” contact. (This also means that it will
“make late” when activated in the opposite direction.)
• The auxiliary contact is also called “NORMALLY CLOSED” (NC), because the auxiliary
contact will be closed when the main contacts are open.
• Please note that the above term “NORMALLY” has nothing to do with NORMAL UPS
OPERATION.
X005 (Output Relays)
Battery operation signals are received with a 30-second delay. This function is inactive during
battery test. Common fault relay facility is programmable (standard factory setting: 10 sec.)
See APC Silcon User Guide for details.
Maximum nominal voltage on contact circuits is 277VAC. If two different phases are involved,
maximum phase to neutral voltage should be below 160VAC. Please note that phase L1 is
already present on the System Integration Interface board, supplied from the Service Bypass
Panel. Therefore, if a phase is needed for alarm or signal purposes, Phase L1 should be used.

Parallel Board

CAUTION!
Control cables must be separated from AC and DC power cables.

Parallel Board
990-4045a

Installation Guide APC Silcon 240-320kW 400V UPS

External Connection

The built-in parallel board connects two or more UPS systems in parallel, either to obtain
increased system reliability or to obtain higher output power. The parallel board also ensures
correct load-sharing between paralled systems.

NOTICE!
For reliability reasons, APC recommends separate battery packs in redundant/parallel
conigurations.

To prepare the UPS for parallel/redundant mode, disconnect all sources of AC and DC power
supply to the UPS and connect the ribbon cable from the parallel board to the main controller
board (the ribbon cable is delivered with the UPS).

CAUTION!
DO NOT connect ribbon cable between controller and parallel card in single configurations.
Ribbon cable is for parallel operation only.

Complete the parallel system set-up by connecting the external control cables (see below).
Follow the instructions in the “Programming Parameters for Advanced Parallel” section of this
guide to execute necessary re-programming.

from APC (part number AP9505 or AP9505i) for all models of Triple Chassis.

4.7.3.3 Daisy-chaining the APC Silcon Triple Chassis
If you need more than the three card slots available with the APC Silcon Triple Chassis, or if
you want to use other external management peripherals, you can daisy-chain external
management peripherals together, provided that the total amperage of all installed
management peripherals — cards and external — does not exceed the supplied amperage. (See
“Determining Power Requirements:”).

NOTICE!
When daisy-chaining Triple Chassis units, you may need to use a power adapter.

990-4045a

Installation Guide APC Silcon 240-320kW 400V UPS

External Connection
To add card slots, you can daisy-chain the APC Silcon Triple Chassis with the standard Triple
Chassis (AP9604) management peripheral, installing the APC Silcon Triple Chassis closer to
the UPS.
4.7.4 Powering the APC Silcon Triple Chassis
The APC Silcon Triple Chassis supplies power to the installed management peripheral cards
and to the Monitoring port, allowing you to power multiple management peripherals.
4.7.4.1 AP9604S Power Considerations
The AP9604S model of the APC Silcon Triple Chassis receives its power from the UPS through
the power connector of the Silcon UPS cable. If the total current required by all the installed
management peripherals exceeds 500 mA, you must use a 24 VDC power adapter. To find out
whether you need additional power, see “Determining power requirements”.
4.7.4.2 Power Adapters
APC offers two models of 24 VDC power adapter.
• The standard adapter (AP9505) can provide an additional 400 mA.
• The universal adapter (AP9505i) can provide 850 mA.
4.7.4.3 Using a Power Adapter
To use the adapter, plug it into a protected power outlet and into the Optional Power port of
the APC Silcon Triple Chassis.

NOTICE!
If the power adapter loses power because of a UPS shutdown, its attached management
peripherals may not operate properly, thus adversely affecting the UPS and its protected
equipment.

4.7.4.4 AP9604SR Power Considerations
The AP9604SR model receives its power from the UPS through the supplied 24 VDC universal
adapter. The total current required by your management peripherals must not exceed the 850
mA limit of the power adapter. See ““Determining power requirements”.
4.7.4.5 Determining Power Requirements:
To determine the total amount of current required by your management peripherals, add the
individual current requirements for each management peripheral to be installed with the APC
Silcon Triple Chassis to the current requirements of the chassis itself. Refer to this table

peripheral cannot
identify UPS model or
nominal output voltage.

The management
peripheral firmware
does not support 3-phase
UPSs.

You may be able to upgrade the
firmware of the management
peripheral. Call APC Customer
Support.

4.7.5.1 If Problems Persist
For problems not covered in the troubleshooting chart or for persistent problems, follow this
procedure:
1) Note the serial number and date of purchase of the APC Silcon Triple Chassis. Contact APC
Customer Support at the phone number or address that is listed in this manual.
2) Be prepared to provide a description of the problem. A technician will help solve the
problem over the phone, if possible, or will give you a return material authorization (RMA)
number.
3) If the APC Silcon Triple Chassis is under warranty, repairs are free of charge. If the
warranty has expired, there will be a nominal charge for repair.

4) Pack the APC Silcon Triple Chassis carefully in its original packaging, if possible. Do not
use polystyrene beads for packing. Damage sustained in transit is not covered under the
warranty. Enclose a letter in the package with your name, address, RMA number, a copy of
the sales receipt, daytime phone number, and payment (if applicable).
5) Mark the RMA number clearly on the outside of the shipping carton. The factory will not
accept any materials without this marking.
6) Return the Triple Chassis by insured, prepaid carrier to the address given to you by APC
Customer Support.
4.7.6 Product Specifications
4.7.6.1 Monitoring Port Pin Assignments
The Monitoring port is a 9-pin communications port. The port operates with no flow control at
a rate of 2400 baud. The data format is 8 data bits with 1 start bit, 1 stop bit, and no parity.
When the Triple Chassis operates with simple signalling, the following limitations and
capabilities apply to the Monitoring port:
• Pins 3, 5, and 6 are open collector outputs which must be pulled up to a common
referenced supply no greater than +40 VDC. The transistors are capable of a noninductive load of 25 mA. Use only Pin 4 as the common.
• The output at Pin 2 generates a low-to-high RS-232 level when the device is
signalling an On Battery condition. The pin is normally at a low RS-232 level.
• The UPS is signalled to shut down when a high RS-232 level is applied to Pin 1 for
4.5 seconds. Shutdown is also dependent on the UPS status.
When the Triple Chassis operates with advanced signalling, the following limitations and
capabilities apply to the Monitoring port:
• Pin 7 is unassigned.
• DC operating voltage is available on Pin 8. This voltage may be from the UPS or from
an external adapter, whichever is greater.

Programming Parameters for Advanced Parallel Operation

To use the advanced parallel functions, the following parameters must be programmed:
1. “Station number”
2. “Highest station address”
3. “Advanced power management”
4. “APM test mode active”
5. “Battery connection”
5.3.1 Description of Settings
1. “Station number”
• Valid station numbers: 1-9 stating the UPS parallel address in system.
2. “Highest station number”
• Valid station numbers: 2-9 stating the number of UPSs in system.
3. “Advanced power management”
• “Disabled”: Advanced Power Management is inactive.
• “PARALLEL+1”: Advanced Power Management is activated when the system operates
as PARALLEL N+1, meaning that one system can be isolated without overloading the
remaining systems (N systems/UPSs).
• “REDUNDANT+1”: Advanced power management is activated when the system
operates as REDUNDANT N+1, meaning that one system can be isolated without
overloading the remaining systems (N systems/UPSs) with one spare system.
4. “APM test mode active”
• “No”: Stand-by-time will be 24 hours - on-line time will be 48 hours (xN systems).
• “Yes”: Stand-by-time will be 1 min. - on-line time will be 2 min (xN systems).
5. “Battery connection”
• “Separate”: Separate battery for this UPS.
• “Common”: Common battery in a parallel system.
NOTICE!
“Common”: Common battery in a parallel system. When this setting is chosen, the highest
battery temperature that can be found in the parallelled systems (for charge voltage
compensation).

NOTICE!
Common battery pack is a technical possibility.
However, APC recommend separate battery pack due to a higher safety degree in connection
with redundant/parallel operation.
The UPS system is designed for both situations.

990-4045a

Installation Guide APC Silcon 240-320kW 400V UPS

Programming Parameters
5.3.2 Programming example
Example with four systems in parallel with separate batteries.
• Programme the station addresses 1-4: 1 for UPS 1, 2 for UPS 2, 3 for UPS 3, and 4 for
UPS 4.
• All UPS systems have to be programmed to “Highest station address”:4.
• If APM is not to be tested, “APM test mode active” must be “NO”.
• If a system is isolated due to service, the station numbers must be reprogrammed for the
remaining active systems starting with number 1 and ending with maximum. number
of active systems. No number must be left in this sequence. Furthermore, “Highest
station address” must be changed to number of active UPSs in parallel.

Intersystem Synchronization Unit

Intersystem Synchronization Unit System (ISU System)
The ISU system consists of inter-connected ISUs. One ISU system may consist of up to 5 ISUs,
regardles of ISU configuration. The ISU system synchronizes the voltage of parallel operation
systems running in battery operation.
The ISU system may also include one or more external synchronization sources,
e.g. a gen-set or a non-APC Silcon UPS system.
Synchronization accuracy of the ISU is better than 2o.

Remote Display

With the remote display unit data may be displayed at distances of up to 25 m from UPS. For
extended communication distance, see section below.
Remote display may easily be connected to UPS via one of the two serial communication ports
on the communication interface board.
To obtain a transmission distance of up to 3.2 km normal RS232C signal levels must be
converted to a long distance communication standard. The converter must be placed outside
the UPS cabinet.
6.4.1 Extension of Remote Display Communication Distance
Remote display communicates with the UPS through a 3-wire RS232 interface. Remote display
is a DTE (Data Terminal Equipment) employing a SUB-D 9-pin female connector.
Communication speed: 9600 bps.
For communication distances, see Table 1. Insert converters if longer distances are necessary,
or if communication cables are led through magnetically noisy areas. Converters must comply
with local regulations
