Step 3: Remove the
Switching Power Supply
Board

1. Loosen the eight hexalobular screws that secure the protective plastic cover

to the control pan and remove the cover.

Important: Mark all connections and wires before removal to avoid

incorrect wiring during reassembly.

2. Disconnect the cables from connector XA and XUV on the switching power

supply board (see

below). Also, carefully remove the ribbon cable

from XA from the cable standoffs on the pulse transformer board.

3. Remove the five screws that secure the board to the control EMI shield and

remove the board.

Important: The switching power supply board is directly connected to the

pulse transformer board at connectors XSW and XSW1. Be sure
to carefully pull the board straight up during removal.
