Split Battery Feed - ADC FCS-717 2B Technical Practice

Installation and Test
Split Battery Feed. For a split battery feed do the following (see
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.
1 Remove and discard the jumper between TB1 and TB2.
2 Connect the wire from CO battery A to TB1 (-48V_A) termination point.
3 Connect the wire from CO battery B to TB2 (-48V_B) termination point.
4 Connect the wire from CO battery return A to TB4 (RTN_A) termination point.
5 Connect the wire from CO battery return B to TB3 (RTN_B) termination point.
6 Connect the CO battery return wire from TB4 on the COT shelf to the CO battery return termination point.
7 Connect the CO battery return wire from TB3 on the COT shelf to the CO battery return termination point.
8 Connect the CO battery wires from TB1 (-48V_A) and TB2 (-48V_B) on the COT shelf to the equipment bay
fuse panel termination points.
When the FCS-717 List 2B 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.
