The contactor has a mechanical lock that interacts with the door to start the racking.

2. Using a slim screwdriver tool, introduce it through the door hole until it reaches the pin that is locking the door.
3. Move up the tool to release the locking pin that is locking the door.
1. Close the door bolting all the screws.
2. Ensure that the contactor is open “OPEN”.
