INSTALLATION INSTRUCTIONS
Step 8: Tighten the gland fitting to the
cable such that the leading edge of the
fitting is 1" (25 mm) back from the braid
pigtail. Be careful to leave enough cable
to easily reach the junction box without
straining the cable.
Step 9: Mount NEMA 4X junction box (not
supplied) to support structure. The junc-
tion box should have one opening for in-
coming power and a 1" (25 mm) opening
for the heating cable. For roof-and-gutter
installations, mount box underneath roof
eave if possible.
Install the completed cable connection
and gland fitting into the 1" (25 mm) open-
ing. Tighten down grounding lock ring.
The cable should come up to the junction
box from underneath, or should have drip-
loop of cable provided.
Step 10: The incoming power cable
should also be provided with a drip-loop
before it enters the enclosure. Connect
the power conductors to the cable leads.
Connect the incoming supply ground wire
to the cable braid and to the green ground
wire. Crimp the ring terminal to the other
end of the green ground wire and then
connect it to the grounding screw on the
lock-ring.
End Termination
Step 13: Cut back overjacket 0.5" (12
mm).
Step 14: Trim ALL of the braid strands
back to the overjacket with scissors
Step 15: Fill the smaller end cap with RTV.
Step 16: Slide the end cap on the end of
the cable until fully seated.
Step 17: Put a small amount of RTV into
the opening of the larger over-cap.
Step 18: Slide
the over-cap
over the end cap
until fully seated.
Step 11: Secure the water-tight cover to
the junction box. Before the system is
energized, make sure it is connected to a
ground-fault-circuit-interrupting (GFCI or
ELCI) type of outlet or circuit breaker.
Step 12: The cable installation instructions
are provided separately.
