Performing Preventive Maintenance
The PDU requires very little preventive maintenance. However, the system should be
inspected periodically to verify that the unit is operating normally.
8.2.1
DAILY Maintenance
Perform the following steps daily:
1.
Check the area surrounding the PDU. Verify the area is not cluttered, allowing
free access to the unit.
2.
Verify the air intakes (vents on front of cabinet) and exhaust opening (on top of
the cabinet) are not blocked.
3.
Verify the operating environment is within the parameters specified in Chapter 9,
Product Specifications," and paragraph A.1 on page A−1.
4.
Record the check results and any corrective actions in a suitable log.
8.2.2
PERIODIC Maintenance
Periodic inspections of the PDU should be made to determine if components, wiring,
and connections exhibit evidence of overheating. Particular attention should be given
to bolted connections. Maintenance procedures should specify that the bolted
connections be retorqued to values listed on labels posted on the equipment.
Refer to the distribution panel manufacturer’s circuit breaker application and
maintenance literature for recommended maintenance practices and procedures.
8.2.3
ANNUAL Maintenance
Annual preventive maintenance, if required, should be performed only by authorized
service personnel familiar with maintenance and servicing of the PDU. Contact an
Eaton service representative for more information about service offerings.
