6.2.2 PERIODIC Maintenance
Periodic inspections of the IAC 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.
6.2.3 ANNUAL Maintenance
Annual preventive maintenance, if required, should be performed only by authorized
service personnel familiar with maintenance and servicing of the UPS system. Contact your
Eaton service representative for more information about service offerings.
6.3 Short Circuits
Short circuits are not considered normal phenomena in UPS applications. Tripping of
protective devices due to low impedance short circuits should be thoroughly investigated
for damage to conductors, insulation, and the protective devices in accordance with the
manufacturer’s recommendations.
6.4 Recycling the Used IAC
Contact your local recycling or hazardous waste center for information on proper disposal
of the used IAC.
C A U T I O N
Do not discard waste electrical or electronic equipment (WEEE) in the trash. For proper
disposal, contact your local recycling/reuse or hazardous waste center.
6.5 Maintenance Training
A basic training course, available from Eaton, gives you a competent working knowledge of
the UPS system operation and teaches you how to perform first level corrective
maintenance. For more information about training and other services, contact the Eaton
Help Desk for Powerware products (see page 1-6).
