3 Remove the two screws that secure the leveling bracket on the rear of the
PDU. Reinstall the screws to hold the rear cover on the PDU in place.
You should support the PDU as far into the pedestal as you can without
letting it drop to the bottom of the pedestal, but watch your hands! It
becomes more difficult to support the PDU the further into the pedestal
it is inserted. The PDU is held in its proper position only when the
mounting screws on its faceplate are tightened.
