the alignment tab of the bracket is resting on the bottom of the slot.

the two 10-32 self tapping screws to 32 lb•in (3.6 N•m) to secure the
swing-out latch bracket to the right hand unit support.

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.
