– Mount the AC power connector using the hardware provided. The socket mounting pad
rests against the outside of the back panel. The connector should be oriented so ground
connector is closest to the chassis bottom plate.
– Install the back panel decal. The top of the decal is aligned with the top of the chassis.

Back Panel Auxiliary Power Connector
Find the auxiliary power female socket connectors in the Auxiliary Power Connector Hardware
package. Examine the pin numbers on the connector. As each wire is inserted in the following
steps, make sure it clicks in place; then check the pin number to make sure it has been inserted in
the correct hole. This is critically important. Equipment damage may result if the following
connections are not made correctly.
– Cut one 6-inch piece of medium expandable sleeving. Cut two pieces of medium heat-
shrink tubing, each about 3/4-inch long. In the following steps, nine wires will be prepared
and inserted into the auxiliary power connector. These wires should first be threaded
through the sleeving and tubing.
– Prepare a 10-inch long #22 black wire. Attach a Molex terminal (0.156 pitch) on one end
and a female socket connector on the other end. Thread the wire through the expandable
sleeving. Insert the female socket to
position #1
on the auxiliary power connector. Leave
the other end free; it will be connected later.
– Prepare a 10.25-inch long #22 white wire. Attach a Molex terminal (0.156 pitch) on one
end and a female socket connector on the other end. Thread the wire through the
expandable sleeving. Insert the female socket to
position #2
on the auxiliary power
connector. Leave the other end free; it will be connected later.
– Prepare a 10.5-inch long #22 white wire. Attach a Molex terminal (0.156 pitch) on one
end and a female socket connector on the other end. Thread the wire through the
expandable sleeving. Insert the female socket to
position #3
on the auxiliary power
connector. Leave the other end free; it will be connected later.
– Prepare a 10.75-inch long #22 red 600 V wire. Attach a Molex terminal (0.156 pitch) on
one end and a female socket connector on the other end. Thread the wire through the
