Removing and Replacing the Power Supply

Installing an AC-Input Power Supply

Warning The plug-socket combination must be accessible at all times, because it serves as the main disconnecting device. Statement 1019

Follow these steps to install an AC-input power supply:

Step 1 Make sure that the power supply you are installing is not plugged in to a power outlet and that the power cord is not connected to the power supply.

Step 2 Remove the two Phillips-head screws from the power supply filler plate (if a filler plate is present).

Step 3 Remove the power supply filler plate (if one is present) and set it aside.

Caution Use both hands to grasp a power supply.

Step 4 Grasp the power supply handle with one hand. Place your other hand underneath to support the bottom of the power supply, as shown earlier in Figure 4-8.

Step 5 Slide the power supply all the way into the power supply bay.

Step 6 Using a screwdriver, tighten the two captive installation screws (see Figure 4-1) on the front panel of the AC-input power supply.

Step 7 Make sure the power supply power switch is in the off position (O).

Step 8 Before you connect the power supply to a power source, ensure that all site power and grounding requirements described in the Site Preparation and Safety Guide have been met.

Step 9 Plug the power cord into the power supply (see Figure 4-9).
