Chapter 1 Introduction
A parallel system with up to four 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®Computer
Area Network (CAN) Bridge Card provides connectivity for system
metering and operational mode control. The parallel system consists of
two to four UPSs, each with a parallel CAN Bridge Card and a parallel
cabinet.
Figure 1 shows the Powerware 9355 UPS and an optional Extended
Battery Module (EBM).
