Before You Begin
ATTENTION: De-energize all power sources to the Motor Control Center before
opening any section or unit doors. Verify that all power is OFF, as per NFPA 70E,
Standards for Electrical Safety Requirements. Failure to de-energize all power
sources can result in severe injury or death.
ATT EN TI ON : To prevent personal injury or damage to equipment, make sure
that the unit operator handle is in the OFF/O position before removing plug-in
units.
ATT EN TI ON : 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.
Secure the Support Pan and Change the Door Latch

5. Disconnect the Feeder unit load wires and pull the load wires away from
the unit so the unit can be removed from the section.
6. Mark and disconnect control circuit wires if they interfere with the
removal of the Feeder unit.
7. Remove other cables or devices that prevent the unit from being
withdrawn.
8. Disengage the captive latches at the front of the unit, one at the top and
one at the bottom of the unit.
Units that are 2.0 space factor and larger have two latches at the top.
Units that are 0.5 space factor do not have captive latches. After you open the
unit door, push the latch mechanism to the left with your right hand and then
remove the unit from the section.
9. Pull the unit forward (outward), approximately 3 in. (7.5 cm) out of the
MCC, by using the handle provided at the lower left of the unit and the
tab in the upper right of the unit as finger holds.
Reposition your hands as necessary to properly support the unit while you
are removing the unit from the MCC.
ATTENTION: Plug-in MCC units can be heavy or awkward to handle.
Use an assistant or a platform lift device if necessary to help you handle
the unit.
10. Remove the unit from the MCC.
11. Carefully install protective caps or close manual shutters after the unit is
removed.
Automatic shutters close as units are removed.

Add the screw to the Feeder unit support pan and the unit support pan above
the Feeder unit, if one is installed.
You can use an industrial, battery-powered screwdriver with a strong magnetic
bit. Use a driver bit extension. We recommend placing a cloth near the work
area to catch the screw if it falls from the driver bit. You can use a small pry bar
between the right-hand edge of the unit support pan and the right-hand unit
support to better align the holes on the left-hand edge of the unit support
pan. Inserting these screws can take more than one attempt.

The latch angle bracket has two tapped holes, but only one hole is used for
mounting. The tapped hole used depends on where the Feeder unit was
mounted in the section:
• If the Feeder unit was mounted directly below the top horizontal wireway
pan, then the bottom tapped hole of the latch angle bracket is used to
mount the bracket to the right-hand unit support.
• Otherwise, use the top tapped hole of the latch angle bracket.

Install Units
Follow these steps to install the units.
ATT EN TI ON : 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.
ATT EN TI ON : Plug-in MCC units can be heavy or awkward to handle. Use an
assistant or a platform lift device if necessary to help you handle the unit.
1. Remove the protective caps from the stab openings or open the manual
shutters if present (automatic shutters open as the units are inserted).
2. Place the unit on the unit support pan and slide it into the section until it
is flush with the front of the structure and the power stabs are connected to
the vertical bus.
ATT EN TI ON : For 0.5 space factor units, a style 3 unit-support pan with bushing
must be used below the unit for proper operation of the latch/interlock
mechanism. If the unit support pan with bushing is not used, the unit could be
removed under load, resulting in injury or death.
Reposition your hands as necessary to properly support the unit while you are
installing the unit into the MCC.
For Feeder units, you need to tilt the top of the unit slightly to the rear to avoid
interference with the top angle latch bracket. If you do not have enough
clearance, you need to loosen the angle latch bracket screw (approximately
two turns) to install the unit.

IMPORTANT
Unit support pan above the unit not
shown for clarity.
3. For all units 1.0 space factor and larger, secure the unit by tightening the
top and bottom captive latches to 22 lb•in (2.5 N•m).
Units that are 2.0 space factors or larger have two captive latches on the top
of the unit and one on the bottom of the unit.
Top captive latch must be rotated to vertical and engage behind the front
flange of the unit support pan above the unit.
The bottom captive latch must be rotated to vertical and engaged into the slot
of the unit support pan as shown.
Install New Door Latch Screw and Label
4. Connect the marked unit load wires.
5. Connect the marked control wires.
6. Verify that all power and control wires have been connected properly and
to the proper phases.
Follow these steps to install the new door latch.
1. On the Feeder unit door, remove the ¼ turn door latch in the upper righthand corner of the door.
2. Insert the ¼-20 pan-head screw, with the screw head on the outside of the
door, thru the open hole in the upper right-hand corner of the door.

¼-20 Pan-head Screw
Screw Retainer
3. Install the screw retainer over the threaded end of the screw.
Leave a slight gap between the screw retainer and the inside of the door so
the screw retainer is not tight against the door. This provides easier
alignment of the Door Screw with the latch angle bracket.
4. Clean the front door surface, just below the pan-head screw, by using
window glass cleaner and a clean cloth.
5. Align the door-screw torque label with the door edges.
6. Gently work out air bubbles from under the label if they are present.
7. Ensure that all tools, hardware, and other debris have been removed from
the units and section.
8. Close and secure all open unit doors.
ATT EN TI ON : 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.
9. Power up the equipment in accordance with CENTERLINE 2100 Low
Voltage Motor Control Centers Installation Instructions, publication
2100-IN012
and as per NFPA 70E, Standards for Electrical Safety
Requirements.
