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!
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 utility. 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 “Programming” section 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.
Read and pay attention to this important information.
CAUTION!
This unit contains components sensitive to electrostatic discharge (ESD). If you do not follow the ESD
procedures, you may cause severe damage to electronic components.

4.3 Parallel Board
CAUTION!
Control cables must be separated from AC and DC power cables.
Parallel Board
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 parallel systems.
NOTICE!
For reliability reasons, APC recommends separate battery packs in redundant/parallel
configurations.
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 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 instructions in section 5.3 Programming of this guide to execute necessary
reprogramming.

4.6 SmartSlot for APC Silcon 240-320kW UPS
A UPS system alone provides excellent protection from brief power problems. However, during
an extended power outage an unattended computer system will eventually shut down due to
battery capacity exhaustion. To prevent data corruption when the UPS shuts down, the
computer must be informed by the UPS of impending shut down and take appropriate filesaving measures. This important function is called UPS monitoring. The UPS's computer
interface port is the means by which your UPS communicates with a computer system.

away from batteries.
b) Use identical battery types and numbers when replacing batteries. See battery supplier
manual for further details.
c) CAUTION - Do not dispose of batteries in a fire. Batteries may explode.
d) CAUTION - Avoid rough treatment and opening of batteries. Released electrolyte is harmful
to skin and eyes, and may be toxic.
e) CAUTION - Batteries may cause electric shocks and high voltage short-circuit current.
Follow the precautions below when working with batteries:
1. Remove watches, rings and other metal objects
2. Use tools with insulated handles
3. Wear rubber gloves and boots
4. Do not leave tools or metal parts on top of batteries
5. Disconnect charging source prior to connecting batteries
6. Determine if the battery is inadvertently grounded. If inadvertently grounded, remove
unwanted ground source. Any contact with grounded batteries may result in electric
shocks. The likelihood of such shocks will be reduced if grounds are removed during
installation and maintenance.
Installation and use of this product must comply with all national, federal, state, municipal or
local codes. If you need assistance, please have your UPS model and serial number ready and
call APC. See “How to Contact APC” in this guide.

4.8.1 EPO Principle
Diagram for Emergency Power Off (EPO) principle has to be established prior to EPO and UPS
installations. Battery Breaker Box and switch gear must be installed with “shunt trip”.
Use external power supply from “Utility” and UPS output before reaching Q002, when tripping
Battery Breakers and switchgear.
EPO circuit and UPS are interconnected to “OFF” and “ON” push buttons, through the System
Integration Interface card terminals X001. On the System Integration Interface card, the
selection switch S002 for internal or external power supply may be set.
S002
Choose either: Emergency shutdown connection between:
Position 1, internal supply X001:3 and X001:4
Position 2, external supply X001:1, + 12V and X001:2, GND
EPO switches must have break functions. Supply current loop of 20mA internally or externally
by selecting switch S002 on System Integration Interface. Use external supply with 12Vdc or
20mA current generator.
The EPO switch is interconnected to an electronic control system (not available from APC)
supplying the Battery Breaker Box and switch gear tripping function with an external 480/
277Vac 50/60Hz supply from Utility 2 (if available) or Utility 1 and UPS output before Q002.
The combination of 2 break functions (one for UPS system and one for external switch gear)
allows for a quick system shutdown in an emergency situation.
NOTICE!
Emergency Power Off function requires a special Service Bypass Panel with tripp function
breakers.

5.3 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
• “REDUNDANT+1”: Advanced power management is activated when the 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.
as PARALLEL N+1, meaning that one system can be isolated without overloading the
remaining systems (N systems/UPSs).
operates as REDUNDANT N+1, meaning that one system can be isolated without
overloading the remaining systems (N systems/UPSs) with one spare 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 is used (for charge voltage
compensation).
NOTICE!
Common battery pack is a technical possibility.
However, APC recommends separate battery pack due to a higher safety degree in connection
with redundant/parallel operation.
The UPS system is designed for both situations.
5.3.2 Programming Example
Example with four systems in parallel with separate batteries.
• Program 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.
990-4049
52 Installation Guide APC Silcon 240-320kW 480V UPS
Programming
• If APM should not 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 numbers must be left in this sequence. Furthermore, “Highest
station address” must be changed to number of active UPS’s in parallel.
5.4 Battery Monitor
Installation of new batteries:
To avoid false alarms, the above procedure MUST be followed.

With the remote display unit data may be displayed at distances of up to 25m from UPS. For
extended communication distance, see 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 3.2km 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
The remote display communicates with the UPS through a 3-wire RS232 interface. The 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 below. Insert converters if longer distances are
necessary, or if communication cables are led through magnetically noisy areas. Converters
must comply with local regulations

1. Between utility supply and UPS input, in a 3-phase Delta-service-phase or midpoint of 2
phases (grounded)
2. Between utility supply and UPS input for galvanic isolation
3. Between UPS output and load for galvanic isolation
4. Between UPS output and load for voltage stepping from 480V - 208V/Y 120V required
Do not use switch gear to bypass isolation transformers. If bypassed, damaging circulation
currents may occur, even with a unity turn ratio.
Coupling Methods
Configuration of isolation transformers is as Delta-WYE with accessible neutral (Dyn11)
NOTICE!
Check correct phase connection of inputs and outputs.
CAUTION!
At 100% switch mode load, the neutral must be rated for 173% output phase current.
Recommended use:
• 3 wires in/out
• 3 wires in/4 wires out
• 4 wires in/out
NOTICE!
All external cable dimensions are recommeded sizes only. Refer to local regulations.
6.5.1 Requirements on Site
All isolation transformer parts are accessible from front or top (cable entries accessible from
bottom). Isolation transformer may be placed close to walls, allowing free space for the front
door to open. Allow free space for ventilation slots for sufficient cooling.
Do not expose isolation transformers to direct sunlight.
