Connect the CO Battery (Figure 5).  

Connect the CO Battery (Figure 5).  The FCS-719 List 4A

COTS may be powered from a single battery feed or from a split battery feed where you would
connect Battery A (-48V_A) for Systems 1 and 2, and Battery B (-48V_B) for Systems 3 and 4.

1

For split battery feed:

a

Remove and discard the jumper between TB1 and TB2.

b

Connect the wire used for the CO battery A to TB1 (-48V_A) termination point.

c

Connect the wire used for the CO battery B to TB2 (-48V_B) termination point.

d

Connect the wire for the CO battery return to TB3 (BATT RTN) termination point.

e

Connect the CO battery return wire from TB3 on the COTS to the CO battery return
termination point.

f

Connect the CO battery wires from TB1 (-48V_A) and TB2 (-48V_B) on the COTS to the
equipment bay fuse panel termination points.

2

For single battery feed:

a

Connect the wire used for the CO battery A to TB1 (-48V_A) termination point.

b

Connect the wire for the CO battery return to TB3 (BATT RTN) termination point.

c

Connect the CO battery wires from TB1 (-48V_A) on the COTS to the equipment bay fuse
panel termination points.
