4.2 System Integration Interface

External Connection

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.

4.3 Parallel Board

CAUTION!

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

Parallel Board

990-4053

Installation Guide APC Silcon 480kW 400V UPS 13

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.
