Air Conditioned Equipment Cabinets
If your control or group enclosure is equipped with an air conditioning unit, it is very important
to observe the following precautions. (Failure to do so can result in moisture damage to electri-
cal components.)
• Maintain the integrity of the cabinet by using sealed knockouts and sealing any holes
made during installation.
• Do not run the air conditioning while the cabinet doors are open.
• If you turn the air conditioner off while it is running, wait at least five minutes before
restarting it. Otherwise, the compressor may be damaged.
• Observe the recommended thermostat setting (75 degrees) and follow recommended
maintenance schedules.
• Make certain that the air conditioning drain tube remains clear to avoid water accumula-
tion in the unit.
