Installing equipment
1 Set the main circuit breaker on the replacement PDU to OFF (down).
2 Position the replacement PDU and gently push it into the pedestal.
Note: Be sure you push the unit straight back, so the connector on the
rear will seat properly with the blower unit connector. It may be easier
to position the PDU if you temporarily pull the blower unit out several
inches.
