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.
