Chapter 4 Removal and Replacement Procedures

Removing and Installing the DC-Input Power Supply

Installing the DC-Input Power Supply

Warning Before performing any of the following procedures, ensure that power is removed from the DC circuits. To ensure that all power is removed, locate the circuit breakers or fuses on the DC power lines that service the DC circuits. Turn OFF the DC power line circuit breakers and remove the DC power line fuses. Statement 322

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

To install a DC-input power supply, follow these steps:

Step 1 Ensure that the system (earth) ground chassis connection has been made.

Step 2 Verify that power is off to the DC circuit that feeds the power supply that you are installing.

As an added precaution, place the appropriate safety flag and lockout devices at the source power circuit breaker, or place a piece of adhesive tape over the circuit breaker handle to prevent accidental power restoration while you are working on the circuit.

Step 3 Remove the new DC-input power supply from its protective packaging.

Step 4 Verify that the power switch is in the off (0) position on the power supply that you are installing.

Step 5 Grasp the power supply handle with one hand, and place your other hand underneath the power supply. Slide the power supply into the power supply bay. Make sure that the power supply is fully seated in the bay. (See Figure 4-2.)

Note The DC power supply is equipped with an EMI gasket on the top, bottom, and sides (on the front edge) of the power supply. When sliding the power supply into the power supply bay, be careful not to damage the EMI gaskets.

Step 6 Tighten the two power supply captive installation screws.

Step 7 Remove the plastic cover from the terminal block.

Step 8 Attach the appropriate lugs to the source DC wires. The maximum width of a lug is 0.300 inch (7.6 mm).

Either insulated crimp-on spade lugs or insulated crimp-on ring connectors can be used on the source DC cables. They should be sized according to local and national installation requirements and electrical codes.

Note The wire should be sized according to local and national installation requirements and electrical codes. Use only copper wire.
