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.
DANGER
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.
