Installing a DC Power Supply
Warning Before performing any of the following procedures, ensure that power is removed from
the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel
board that services the DC circuit, switch the circuit breaker to the OFF position, and
tape the switch handle of the circuit breaker in the OFF position.
Complete these steps to install the DC power supply:
Step 1 Place the power supply as shown in Figure 6-18, and then slide it toward the rear panel. You will be able
to feel the chassis hook engage with the slot on the bottom of the power supply.
Step 2 Reinstall the three screws that secure the power supply on the back panel of the chassis.
