Both expansion power supplies require power and communications connections
to the 4010 SFI/O board. Use Steps 1 through 3 to connect a power and
communications harness from the expansion supplies to the 4010 FACP. Both
harness connectors are keyed for correct connection.
1. Connect the 733-950 white harness from P2 of the expansion supply to P14
of the SFI/O board.
2. Connect the 733-951 red harness from P1 of the expansion supply to P13 of
the SFI/O board.
Note:
This connection is optional. It is only needed if you want to power
NACs 3 and 4 on the 4010 FACP from the expansion power supply
instead of the 4010 FACP System Power Supply.
3. Neatly dress the wiring behind the 4010 chassis using the holes provided to
tie-wrap the harnesses.
Both expansion power supplies require connection to the battery terminals (TB8)
on the 4010 SFI/O board.

Expansion Power Supply, you do not need to connect this red (+) wire.
However, you still must connect the black (-) wire.
