How to Install the SQDC Operator Adapter
This guide provides step-by-step instructions for installing the SQDC Operator Adapter for Square 'D' Bulletin 9422 Flexible Cable Operating Mechanisms.
Estimated time: 1h
Tools needed:
Screwdriver, Drill, Wrench
Supplies needed:
Mounting screws, Plate gasket, Nylon washers, Flat washers, Lockwashers, Hex nuts
- Install the mounting plate
Secure the mounting plate and plate gasket inside the enclosure behind the rectangular opening. Use four screws and four nylon washers to secure it in place.
- Assemble the operating handle
Attach the Square 'D' operating handle and cable handle mechanism to the mounting plate. Omit the cap screw and lockwasher that fits into the bottom hole of the operating handle.
- Install the slide arm
Position the slide arm over the handle assembly with the notch facing the door opening. Insert the shoulder collar through the oval slot in the slide arm and secure it with the long cap screw and lockwasher.
- Connect the slide arm to the lock release mechanism
Attach the bottom of the slide arm to the offset arm of the lock release mechanism using two flat washers, two lockwashers, and two hex nuts. Do not tighten yet.
- Adjust the safety lock release mechanism
Check and adjust the roller bracket on the enclosure to ensure the door latch hits the latch stop when closed. Adjust the slide arm length so the safety lock releases just before the master door is fully latched.

- Drill and tap holes for the switch
Drill and tap holes in the panel according to Square 'D' instructions for proper switch mounting.
