Make a small loop in each cable below the fitting
and secure the loop with a U-bolt cable clamp. Position
the U-bolt clamp 1/2" to 3/4" below the terminal fitting.
Securely tighten the nuts on the U-bolt clamp. (See
Figure 13) Cut off the excess cable leaving about 6 in.
below the clamps. Tape the ends of the cables for a
distance of about one inch to prevent fraying.
adjustment nuts on the ends of the two spring guide
rods. Use two wrenches to lock the adjustment nuts in
place by jamming them together tightly. (See Figure
14)
2.5.3
Install the junction box arm on the ring at the
location immediately adjacent and to the right of the
power cord slot. (See Figure 15)
2.5.4
Install the junction box onto the left side of the
junction box arm using the four 1/4-20 locknuts sup-
plied in the bag attached to the strain plate.
CAUTION
Do not attempt to remove the nuts attached to the studs
protruding from the back of the junction box.

Use a 5/8” torque wrench and rotate the winch
input shaft to approximately 40 Ft. Lbs. to put tension on
the cables. Check the terminal cable fittings to insure
that they have set properly. Cable should not be pulled
into the terminal cable fitting more than 1/4”.
CAUTION
If the cable has moved more than 1/4” through any of the
cable terminal fittings, the fitting has not set properly.

2.5 Completing the Pole-top Assembly
2.5.1
If the device is equipped with a bumper ring
instead of iris-type guide arms, proceed to paragraph
2.5.3. Otherwise, attach both angle brackets to the ring.
(See Figure 14) The double washers must be installed
between the brackets and the ring to avoid possible
interference with the luminaire mounting brackets which
will be mounted to the ring later. Tighten each locknut
until it is snug and then loosen it about one half turn to
allow the bracket to pivot. The bolt, with nut installed,
should turn freely when properly adjusted.
2.5.2
Adjust the guide arms so the distance between
each wheel and the surface of the pole is 1/4 - 1/2 in. It
will be necessary to lift the ring to center the wheels
while checking the clearance between the wheels and
the pole. The adjustment is made by rotating the two
