ATTENTION: De-energize all units before installing or removing.

When installing or removing MCC units, when possible, de-energize, lockout,

and tag-out all sources of power to the MCC. If the MCC units will be installed or

removed with power applied to the main power bus, follow established

electrical safety work practices. Refer to the NFPA 70E Standard for Electrical

Safety in the Workplace publication.

Review your company safety lockout and tag-out procedure.

If power sources are connected to the motor control center, use extreme caution

when inserting units. All buses and the line sides of the inserted units are

energized, and contact with these parts can cause injury or death.

All covers and doors must be in place before applying power to the MCC. If units

are removed, they must be replaced with the appropriate items such as units,

doors, and unit support pans.

ATTENTION: Plug-in MCC units may be heavy or awkward to handle. Use an

assistant or a platform lift device if necessary to help you handle the unit.
