Reference Figure 7
If branch neutral terminal strips (Item 18) are
NOT already installed -- or are full -- then the
branch neutral terminal strip (included) must
be installed. Depending upon the feed location,
the branch neutral can be mounted near the
bottom of the Z-rails -- or mirrored to the top --
on a branch neutral connector. Panelboards
should have one mounted already. On Switch-
boards, mount the branch neutral connector
(Item 17) on the neutral bus using (2) 1/4”-20
screws (Item 15). Mount the neutral terminal
strip (Item 18) on either side of the branch
neutral connector using (2) #8-32 screws
(Item 16). Torque all hardware as follows:
For 1/4”-20 screws, refer to torque on label.
For #8-32 screws, torque to 35 lb-in.

Reference Figure 8
Install the 3.75” cover plate (Item 7) by aligning
it over the 3.75” of selected unit space and
related breakers. Use a 1/4”-20 x 3/8” screw
(Item 14) on each side of the cover plate and
drive into the deadfront rails. Torque all hardware
as specified on the rear of the deadfront. Mark
the circuit ID cards (Item 8) as desired and
mount them to the cover plate by placing each
behind a clear card holder (Item 9) and pushing
the two into the proper pair of holes in the cover
plate next to the proper circuit. Repeat for each
location. Finally, use blank fillers (Item 10) at
every location that doesn’t have a breaker
penetrating through the cover plate.
NOTE: Other cover plates may be required for
proper fit. See filler plate kits listed on the rear
of the deadfront.
INSTALLING COVER PLATE AND FILLERS
13. Ensure that any bus or breaker hardware is
torqued as specified on the rear of the deadfront.
Then replace all the cover plates and gutter
covers. Finally, ensure any fillers are in place
BEFORE
re-energizing the equipment.
