Your application may require the removal or installation of jumpers of the SMCT

accomplished by:
1. Disconnecting the Mechanism Cable and the AC cable.
2. Removing the six (6) screws on the SMDP Board and the two (2) screws located
in the heat sink on the right side of the board.
3. Lifting the Board from the rear center, in the connector area, to avoid damage.
