height, order a blank filler door with hinge hardware and
a snap shelf. See the renewal parts bulletin for ordering
blank doors and gasket materials. The gasket material
lines the inner perimeter of the section. Figure 23 shows
the gasket material mounted to the outside of the door.

Use the following procedure to install a motor control
center unit:

1. Attach the door hinges to the left side of the section,

line up the door with the hinges, then insert the hinge
pins to secure the door. Install a hold-down bracket
with the lower door hinge, but do not tighten the
mounting screw at this time.

2. Place the two tabs on the left side of the shelf into

the appropriate openings in the section structure.

3. Lower the right side of the shelf and snap the two

detents in the right-side flange into the two holes in
the side of the vertical wiring trough barrier, as
shown in Figure 24. Swivel the shelf hold-down
bracket and grounding spring into place and tighten
the lower case hinge.

4. Examine the new unit carefully, front and rear, to

ensure that all screw terminals are tight, all foreign
material and packing are removed, and the insulat-
ing barriers are secure.

5. The unit disconnect must be in the OFF position

before the unit can be inserted into the vertical
section.

6. If necessary, rotate the latches at the top and

bottom of the unit so that they are horizontal.

7. Remove the snap-in cover over the vertical bus

stab-in openings at the appropriate installation
location for the unit to be installed.

8. Lift the unit and place its base on the front horizontal

surface of the snap-in shelf.

9. Slide the unit into the vertical section, then push at

the top and bottom until the stabs are fully engaged
with the vertical bus.

10. Rotate the latches at the top and bottom of the unit

clockwise to engage the latches with the horizontal
shelves above and below the unit. See Figures 25
and 26.

11. Verify the operation of the disconnect handle and

safety interlocks, as described later in this manual.
