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 are 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.
