7.2Standard Modes of Parallel Operation: Normal, Battery, and Bypass Modes
With the Parallel Capacity/Redundant system, the system continues to function automatically to supply AC electrical power to the critical load. There are three standard operation modes:
•In Normal mode, Parallel Capacity/Redundant system functions normally, suppling clean, filtered power from the UPMs to the load.
•In Bypass mode, the SSBM bypass input supplies the load and isolates the UPMs.
•In Battery mode, the battery cabinet supplies DC power, which maintains UPM operation.
The following descriptions provide the Parallel Capacity/Redundant system operating mode differences.
