Chapter 4 Removing and Replacing FRUs

Removing and Replacing the Power Supply

Installation Procedure

Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. Statement 1003

Warning A readily accessible two-poled disconnect device must be incorporated in the fixed wiring. Statement 1022

Warning This product requires short-circuit (overcurrent) protection, to be provided as part of the building installation. Install only in accordance with national and local wiring regulations. Statement 1045

Warning Use copper conductors only. Statement 1025

Warning When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the insulation and conductor. Statement 1002

Follow these steps to install a DC-input power supply, connect it to a power source, and verify its operation:

Step 1 Verify that power is off to the DC circuit or circuits on the power supply you are installing.

Step 2 Grasp the power supply handle with one hand. Place your other hand underneath it as you slowly insert the power supply into the bay (as shown earlier in Figure 4-16).

Step 3 Using a screwdriver, tighten the captive screws on the power supply (see Figure 4-15).

Step 4 Before you connect the power supply to a power source, ensure that all site power and grounding requirements have been met.

Step 5 Connect the DC-input wires to the power supply terminal block. The proper wiring sequence is ground to ground, positive to positive, and negative to negative (see Figure 4-13or Figure 4-14depending on your installation).

The 1400W triple-input power supply has two grounding posts; use the one that is most convenient for your installation.

Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046

Step 6 Replace the terminal cover.

Step 7 Connect the other end of the power cords to a DC-power input source.
