How to Install the ABBLC Operator Adapter

This guide provides step-by-step instructions for installing the ABBLC Operator Adapter for ABB Cable Controlled Large Handle Disconnects.

Estimated time: 1h

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors, Nylon washers, Flat washers, Lockwashers, Hex nuts

  1. Install the adapter plate

    Secure the adapter plate and plate gasket inside the enclosure behind the rectangular opening using four screws and four nylon washers.

  2. Assemble the operating handle

    Attach the ABB operating handle to the mounting plate installed in step 1, omitting the cap screw and lockwasher for the bottom hole.

  3. Install the slide arm

    Position the slide arm over the interlock lever of the ABB operating handle, ensuring the notch faces the door opening, and secure it with the shoulder collar and long cap screw.

  4. 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 flat washers, lockwashers, and hex nuts, but do not tighten yet.

  5. Adjust the slide arm assembly

    Ensure the safety lock in the ABB operating handle releases just before the master door is fully latched by adjusting the length of the slide arm.

  6. Install the door catch

    Attach the door catch to the tapped spacer on the door using screws and lockwashers to prevent the door from opening when the ABB operating handle is in the 'ON' position.

  7. Drill and tap holes in the panel

    Follow ABB instructions to drill and tap holes in the panel for the disconnect, ensuring it is within reach of the cable length.

  8. Install the panel
