Caution: Do not perform maintenance with the rack energized.
Dust Removal
Every six months (or more often, if the environment is particularly dusty) any accumulation of dust should
be cleaned from the rack. An accumulation of dust can impede proper airflow and lead to overheating of
dimmer or control modules. The following areas should be checked and cleaned:
♦ door air filters
♦ door air vents
♦ vents around hand held terminal door enclosure
♦ fan grilles
♦ dimmer module air intake openings
♦ control module air intake openings
The door air filters should be cleaned by washing them. To wash them, first remove them as you would a
household window screen: push the bottom of the frame up, then out of the track. Clean the filters by
spraying water through them. If the filters are particularly dirty, a soapy, grease-cutting cleaner may be used
to remove the dirt, but the filters must then be rinsed with water. The air filters must be completely dry
before they are reinstalled in the rack door.
Removal of dust from the vents, grilles and air intake openings can be done with compressed air or a
vacuum.
Wire Termination Integrity
Every six months, check wire terminations for tightness: bus to bus, bus to lug, and lug to terminal or wire.
Refer to the Installation Manual for the terminal-to-wire torque ratings and for other torque ratings.
