Connecting a Split Battery Feed
When using a split battery feed, -48V_A provides the battery feed for system 1 and 2,
and -48V_B provides the battery feed for system 3.
When the FCS-717 List 4B COT shelf is configured for a split battery feed, insert a
5 amp fuse into the equipment bay fuse panel for each circuit where the PG-Flex CO
battery wires are terminated.
