Reassembly

To reassemble the MCC after testing and maintenance, follow the steps below:

  1. Reinstall Compac 6 units by reversing removal Steps 1–12 in Removing the Compac 6 Control Unit. Reinstall all other units by reversing removal Steps 1–12 in Removing the Control Unit.

  2. Confirm the cam mechanism is in the open position; position the mounting slides of the control unit onto the slots of the mid-shelf. Slide the unit inward to engage the cam mechanism.

    For Compac 6 units, position the mounting slides of the control unit onto the slots of the mid-shelf. Slide the unit inward until the unit is halfway in, then move it inward with a quick push. This movement easily overcomes the compression of the stabs as they engage the vertical bus.

  3. Replace all barriers and cover plates and close and fasten all doors.
