8.3 PREVENTATIVE MAINTENANCE
There are several preventive maintenance routines which should be performed to ensure optimum operating
efficiency of the system is maintained. GE Power Conversion recommends that these are performed bi-
annually, but individual applications may require a different maintenance schedule.
NOTE: All supplies must be isolated before preventative maintenance tasks are performed.
8.3.1 Bi-Annual Maintenance Routine
The following checks should be carried out every six months:
a) Ensure that all ventilation louvres to the cubicle are unobstructed;
b) Ensure the airflow through the cooling ducts is unobstructed.
c) Examine all power terminations for any signs of overheating;
d) Check that all electrical connections are secure. Torque settings are given in Appendix C: Recommended
Torque Settings;
e) Remove any accumulated dust from the system, using a vacuum cleaner with a non-conducting nozzle.
