identifies and shows the location of the circuit breakers in the SIAC-B. The descriptions
provide a brief overview of the SIAC-B breaker use.
•
Maintenance Bypass Breaker
– The Maintenance Bypass Breaker (MBP) transfers the load from the UPS
output to the bypass input feeder.
•
Maintenance Isolation Breaker
– The Maintenance Isolation Breaker (MIS) isolates the UPS from the
bypass feed and the load.
•
Bypass Input Breaker
– (Optional – only three and four breaker configurations) The Bypass Input Breaker
(BIB) provides a single point of input power control to the UPS on single-feed systems or bypass input
power control to the UPS on dual-feed systems. Using the BIB easily removes power from the UPS for
servicing.
•
Rectifier Input Breaker
– (Optional – only four breaker configurations) The optional Rectifier Input Breaker
(RIB) (four-breaker version only) provides a single point of rectifier input power control to the UPS on dual-
feed systems and easily removes power from the UPS for servicing.
