The following descriptions provide a brief overview of the SIAC-B functions:
•
Two breaker configuration: The bypass sidecar contains only a Maintenance Bypass (MBP) and
Maintenance Isolation (MIS) breaker. This allows Maintenance bypass for system repair or maintenance.
The critical load is NOT protected in the Maintenance bypass mode.
•
Three breaker configuration (used with single-feed systems): Maintenance Bypass (MBP) and
Maintenance Isolation (MIS) breakers, and a Bypass Input Breaker (BIB) enable power to completely
bypass the UPS. The UPS can then be safely serviced or replaced without interrupting power to critical
systems.
•
Four breaker configuration (used with dual-feed systems): Maintenance Bypass (MBP) and Maintenance
Isolation (MIS) breakers, and a Bypass Input Breaker (BIB) enable power to completely bypass the UPS. A
Rectifier Input Breaker (RIB) provides a convenient method for removing power from the UPS when using
the maintenance bypass to supply the load. The UPS can then be safely serviced or replaced without
interrupting power to critical systems.
