To install a replacement power cable for a DC power supply (see Figure 64):
Locate a replacement power cable that meets the
specifications defined in Table 30.
Verify that a licensed electrician has attached
a cable lug to the replacement power cable.
Secure the power cable lug to the terminal studs,
first with the flat washer, then with the nut. Apply between 23 lb-in. (2.6 Nm) and 25 lb-in. (2.8 Nm) of
torque to each nut, (see Figure 64).
Route the power cable along the cable restraint towards
the left or right corner of the chassis. If needed, thread plastic
cable ties, which you must provide, through the openings on the cable
restraint to hold the power cables in place.
Make sure the
cable is not touching or in the way of any device components,
and that it does not drape where people could trip on it.
Replace the clear plastic cover over the terminal studs on the faceplate.
Attach the power cable to the DC power source.
Verify that the INPUT OK LED on the power
supply is lit green.
Switch the circuit breaker on the power supply
to the ON position (|)
If more than one power supply is being installed, turn on all
power supplies at the same time.
Verify that the DC source power cabling is correct.
Observe the status of the LEDs on the power supply faceplate. If the
power cable is correctly installed and the power supply is functioning
normally, the PWR OK, BRKR ON, and INPUT OK LEDs
light green steadily.
