Alarm Connections and ABS Power
At the top of the cabinet is a Customer Interface Board for connecting Output Alarms and Alarm
Battery Supply (ABS) to redundantly power the alarms and the VIM1C meter.
The VIM1C receives redundant power from panels 1 and 2 as well as an external ABS connection, so
the ABS connection is not mandatory for proper operation but some customers require its use.
A Return connection is required for operation of the meter and alarms. The Return connection on
the Customer Interface Board is factory wired when internal return buses are ordered, otherwise it
must be field wired to the external return bus.
