Standard 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.
