WARNING
INSTALLATION, SERVICE, MAINTENANCE OR OPERATION SHOULD
BE PERFORMED BY QUALIFIED PERSONNEL ONLY.
4.1 PERIODIC MAINTENANCE
The CSC should be inspected periodically as shown below:
INTERVAL ACTION
1 month (A) Visually inspect high voltage relays through clear
dead front cover.
3 months (A) Perform Control Functions checkout per Section
3.2.1.1 to verify proper operation.
6 months (A) Isolate the CSC and CCR from all sources of
electrical power.
(B) Check all wiring connections for loose or missing
screws. Check terminal blocks and component
connections.
(C) Check for broken or damaged wires and components.
(D) Remove dust build up.
(E) Inspect housing for rust or chipped paint. Clean and
touch up with paint as required.
(F) Re-install all covers and restore primary power to the
CSC and CCR.
4.2 CORRECTIVE MAINTENANCE
In general, corrective maintenance is performed by the replacement of parts rather
than repair when they cease to function properly. The use of easily removable sub-
assemblies facilitates repair. The removal and replacement procedure should be
obvious to qualified maintenance personnel.
