9.
Secure the front of the Power Supply assembly to the rails by installing the
appropriate 1/4” (6.4 mm) length rack screws. (Use optional [not supplied] flat
nylon washers with the rack screws to protect the equipment finish.) The finished
power supply installation will appear as illustrated in
10. At the rear of the unit, install the 8 “captive” screws (see
) through
the top of the power supply chassis into the bottom of the Signal Processor
Frame. Tighten the 8 screws securely.
11. Remove the nuts and lockwashers from the two large electrical posts in the
right compartment of the power supply. Do not discard.
NOTE:
If you will be installing a Redundant Frame Power Supply, position the cables in
steps 12 and 13 over the studs but do not attach the nuts and lockwashers to the studs at
this time.
NOTE:
Steps 12 and 13 below require the following installation order: 1) cable, 2)
lockwasher, 3) nut. Also be sure and torque the nuts to 80 inch/pounds (6.67 foot/
pounds) +/- 5%. These measures will prevent an inferior connection that could overheat.
Do not over tighten; this may strip or break the studs and the power supply then must be
shipped back to the factory for repairs.
