Preliminary Steps Before replacing the power supply filter board, shut off the power; lockout/
tagout the unit; and wait five minutes for the voltage to discharge. Open the
bay door to the power structure.
Replacing the Power Supply
Filter Board 1. Using a meter, test the voltage across the AC line, across the DC bus, and
across the terminals on the power supply filter board.
2. Remove the screw which mounts the Lexan™ guard.

4. Loosen the standoff screws and gently pull the board from the standoffs.
5. Firmly press the new board onto the standoffs and secure the standoff
screws.
6. Connect the wires from the gate driver board to TB1-1 (black) and
