Optional Modes Of Parallel Operation: Maintenance Bypass And Redundant Cbp - Eaton Powerware 9315 Installation And Operation Manual

7.3 Optional 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.
