Overview
Inspect all MCC installations at frequent intervals. Visually inspect the front and back to note any warped piece,
loose bolts or screw undue vibration. Take corrective actions if any of these conditions is found.
Keep the MCC covered to prevent any dripping liquids from falling on it, but do not cover the air vents.
DANGER
There are risks of electrocution and/or burns every time you work on or around electrical equipment.
Disconnect power from the board before performing any maintenance.
Check the terminals of the input line to verify that the equipment is disconnected.
Check the output terminals to verify that there is no feedback.
CAUTION
Limit the using of solvents to remove grease and contaminants to the primary conductors, insulators and metal
surfaces without paint. Do not use alcohol or freon. Use OSHA approved solvents according to local regulations.
Use a nonflammable solvent equal to 300 PPM.
Use solvents in well ventilated areas.
