SECTION 7
Maintenance
There are no wear items in the Parallel Output Redundant Cabinet that require periodic
replacement. However, regular care will assure maximum availability of power.
Keep the ventilation openings in the cabinet free of dust and debris.
Wipe the cabinet exterior with a soft cloth, slightly dampened with water, to remove dust.
Consider performing periodic infrared temperature measurements on the circuit breaker
terminations. This will require access to the cabinet interior. There are hazardous voltages
present and any work must be performed using caution. Only trained service personnel
should perform this work. Elevated temperatures of the terminations usually are the sign of
a loose connection, but can also signal that a breaker is failing. Loose connections should
only be serviced after removal of power.
If the system is powered down, consider removing accumulated dust from the cabinet
interior using a vacuum cleaner.
