  • This equipment must only be installed and serviced by qualified electrical personnel.
  • Turn off all power supplying this equipment before working on or inside equipment.
  • Always use a properly rated voltage sensing device to confirm power is off.
  • Replace all devices, doors, and covers before turning on power to this equipment.
  • When moving MCC sections, follow the instructions in Handling the MCC. The MCC has a high center of gravity, which may cause it to tilt.
  • MCC structures must be secured to the mounting surface. Follow instructions in Securing Structures to the Floor.

MCCs are designed for use in non-hazardous locations. Choose a location for installation that is well ventilated and free from excess humidity, dust, and dirt. The temperature of the area should be no less than 0°C (32°F) and no greater than 40°C (104°F). Protect the MCC from the entrance of water or any moisture. If necessary, protect the MCC from condensation by ordering internal space heaters.
