General procedure guidelines:
STEP
1
The line power and the control power must be OFF before
replacing any fuse. Use a screw driver to remove all of the lids.
Depending on the type of controller there will be two or three
boards connected together, a Control board and one or two Gate
Driver boards.

Gently remove all wires from the top of Gate Driver board by
simply pulling up on the connectors. Do not pull on wires. This
