Uninterruptible Power Systems:
쑺 The IAC-B provides maintenance bypass functions.

installation, but may be installed separate from the UPS cabinet.
8.2.4 Powerware Hot Sync Parallel System
A parallel UPS system with two to four uninterruptible power modules 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 UPM is taken out of service for maintenance or is not
operating properly, a redundant UPM continues to supply uninterrupted power to the
critical load. A Powerware Hot Sync Computer Area Network Bridge X-Slot card provides
connectivity for system metering and operational mode control. The parallel system
consists of two to four UPMs each with a parallel CAN card, and a module tie cabinet or
load distribution panel to act as a tie point. Each UPM requires a separate battery cabinet.
8.2.5 Sync Control
An optional Sync Control m aintains the critical load outputs of two separate single module
Powerware 9390 UPS systems in synchronization. This facilitates the uninterrupted transfer
oftheloadfromoneloadbustoanotherbymeansoftransferswitches.TheSyncControl
is housed in a wall-mounted panel that can be located between the UPS units for easy
wiring.
