8. From inside the building, feed the end of the 30-foot
conduit (INCLUDED and pre-wired from transfer switch)
through the wall to the outside.
9. Remove the threaded lock nut from the conduit coupling.
10. Lift cover. Remove internal
cover plate screw and internal
cover. Remove the knock out
in the lower right corner of
the external connection box.
From the rear of the connec-
tion box, feed wires, 4-pin and
2-pin plugs into box. Slip the
lock nut over wires and plugs
and tighten securely onto con-
duit coupling. Using appropri-
ate fasteners, mount external
connection box over pre-drilled
hole to fully conceal the hole. Seal around the hole and
conduit with silicone caulk from both the inside and out-
side of the building. Also, caulk around the sides and top
of the box to seal the edges to the siding or wall. Connect
wires to lugs; black to black, white to white, and red to red.
Torque nuts to 20 in/lbs. Snap together the 4-pin and 2-pin
plug connector. Loosen nut from grounding lug and attach
ground wire (green) from conduit. Reinstall nut and tighten
to 45 in/lbs. Reinstall internal cover plate and screw. Close
cover and install lock. This wiring is complete.
 The outdoor connection box must be locked to
ensure safety and to discourage tampering.
11. Locate automatic transfer switch with built-in emer-
gency load center in close proximity to the main
distribution panel. The transfer switch can be located
to the left or right of the main distribution panel. Two
(2) feet is the suggested distance (see Figure 11). The
transfer switch may be located a different distance
from the main panel depending on available mounting
area. Using the two (2) foot conduit connected straight
across to the main panel is another option. Always
adhere to local electrical codes during installation. Hold
transfer switch against the mounting surface. Level the
transfer switch and mark the mounting holes. Drill the
appropriate size pilot holes. Mount transfer switch with
built-in load center to mounting surface with appropri-
ate fasteners.

The manufacturer recommends that a licensed elec-
trician or an individual with complete knowledge of
electricity perform the procedures in Sections 12
and 13.

Switch service main circuit breaker to
the OFF (OPEN) position prior to removal
of cover or removal of any wiring of the
main electrical distribution panel. The
wires connected to the service main cir-
cuit breaker remain LIVE or HOT. Avoid contact with
these wires and the service main circuit breaker con-
nection lugs.
