2. Installation
Procedure

1. Apply the supplied compression-type ring tongue terminals to the #8 AWG
power wires. Use the Molex MagnaCrimp Hand Tool (Part No. MCT-8200).
2. Remove the left or right metal cover on the lower, rear of the chassis. The left
metal cover is for PWR B power connections, and the right metal cover is for
PWR A power connections. Ensure that the insulator attached to the back of
the metal cover does not pull loose; it must be intact when you reinstall the
cover plate (see
Step
3. The rear access power wiring can be routed from the power taps directly
downward and out of the bottom of the chassis (perpendicular to the metal
covers) or straight through the cover plate. After deciding which routing path to
follow, use long nose pliers (or the equivalent) to remove the metal knock-out
from the bottom of the chassis or the metal cover.
4. Route the rear access power wires either up through the bottom of the chassis
or straight through the cover plate.
5. Remove the two M4 Phillips-head screws installed in the power taps on the
backplane.
6. Dress the power wires, with the ring tongue terminals attached in
through the appropriate access holes. Attach the #8 AWG wires to the power
taps using the M4 Phillips-head screws from
— Connect the 48V RTN (return or +) wire to the power tap on the left (RTN).
— Connect the 48V wire to the power tap on the right (–48V).
Tighten the M4 screws securely while keeping the ring tongue terminals and
their wires dressed vertically.
7. If power wiring is dressed through the bottom of the chassis, install the small
cable bushings (supplied). Spread the cable bushing open slightly and slip it
over the power wire. Slide the bushing upward into the cable access holes in
the bottom of the chassis and press on the bushing until it snaps, locking it in
place.
8. Reinstall the metal cover removed in
9. Repeat this procedure for the other metal cover.
