7.3Optional Modes of Parallel Operation: Maintenance Bypass and Redundant CBP
There are two optional modes of operation in this Parallel Capacity/Redundant system:
•In Maintenance Bypass mode (optional), the SMB bypass supplies the load and isolates the SSBM and UPMs for maintenance purposes.
•In Redundant CBP mode (optional), if the CBP breaker fails to close during a manual or automatic operation, the SSBM automatically closes the MBP breaker to maintain power to the critical load.
The following descriptions provide the Parallel Capacity/Redundant system optional operating mode differences.
