15.5 Field Replacement of Power Supply

Warning: Ensure that the unit is shut off and power cord disconnected before removing the

power supply to prevent a shock hazard.

15.5.1 Power Supply Removal

1. Using a Phillips screwdriver, loosen the two retaining screws holding the power supply in place, see Figure 14-6.
2. Gently slide the power supply out far enough to allow access to the connectors to the supply and disconnect the two

pin AC input connector and ground spade connector at the right side of the supply,see Figure 14-7.

3. Lift the supply and disconnect the six pin DC output connector at the left side, see Figure 14-8.

15.5.2 Install Power Supply

1.  Connect the six pin connector at the left side of the supply.
2.  Connect the two pin connector and spade lug at the right side of the supply.
3.  Insert the top edges of the supply into the slots at the top edge of the opening and slide the power supply into the

unit, see Figure 14-9.

4. Using a Phillips screwdriver, tighten the two retaining screws holding the power supply in place.
