Introduction
A parallel system with up to three uninterruptible power supplies (UPSs)
can be installed to provide a parallel capacity and/or redundant system.
This load sharing system provides more capacity than a single UPS and
can provide backup, depending on the load and configuration. In
addition, when one UPS is taken out of service for maintenance or is not
operating properly, a redundant UPS continues to supply uninterrupted
®
®
power to the critical load. A parallel Powerware Hot Sync Contoller
Area Network (CAN) Bridge Card provides connectivity for system
metering and operational mode control. The parallel system consists of
two or three UPSs, each with a CAN Bridge Card and a parallel tie
cabinet.

Be sure to check correct polarity (see Figure 19):
S Connect COM Pin 4 to Signal Input 2 Pin 1 on each UPS.
S Connect NC Pin 3 to Signal Input 2 Pin 2 on each UPS.
CAUTION
If polarity or wiring is not correct, the parallel system does not operate normally. For
example, when shutting down one UPS, the remaining UPS transfers the load to bypass
instead of supporting the load. Verify all CAN Bridge Card wiring is correct for proper
operation.
NOTE Signal Input 2 can still be used for building alarms; it is automatically rerouted to
the CAN Bridge Card.
