NOTE
All UPSs in a parallel system must have the same battery configuration. Each UPS
requires a separate battery cabinet.
A parallel UPS system with up to eight 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 built-
in Controller Area Network (CAN) provides connectivity for system metering and operational mode control. The
parallel system consists of two to four UPSs each with a parallel CAN, and an IAC-T, SIAC-T, or SIAC-TB to act
as a tie point and to control the output.
