Maintenance
Connections – Loose connections in the power wiring will generate hot spots. These will cause degradation
of electronic equipment. Periodic inspections should be made to ensure that connections are secure and
that there are no signs of excessive heating such as discoloration, and so on.
Corrosion – If the power module is installed in an environment with high humidity or dampness, electrical
connections may suffer corrosion. Periodically check the power module for corrosion.
Damage

ature. The filters used with these devices should be changed on a periodic basis to insure adequate enclo-
sure cooling is maintained.
Dust
– Periodically check for dust or other particulate buildup on heatsinks and bus bars.
WARNING
Hazardous Voltage: Disconnect all power before performing any
maintenance or examining the power module. Exposed terminals
may carry LETHALLY HIGH VOLTAGES when power is applied.
