Installation
STEP 2.
Insert two
5/8
-inch diameter through-bolts (supplied
by others) in the holes drilled in Step 1. Secure these
bolts loosely with the necessary washers and nuts
so the heads of the bolts project sufficiently
(approximately 3 inches (76 mm) from the face of
the pole) to engage the enclosure mounting frame.
For installation with a switch in the vertical
mounting configuration, mount the communiction
and control unit on the face of the pole oppo site the
switch to allow space for the cable riser.
STEP 3.
Attach an appropriate lifting sling and slowly raise
the sling so it becomes taut. Carefully raise the
control unit to the mounting height and guide it so
the through-bolts projecting from the utility pole
slip into the two keyholes in the enclosure mounting
frame. Lower the enclosure slightly so it bears on
the through-bolts. Fully tighten the bolts and make
sure the washer for each bolt is between the bolt
head and the mounting frame.
STEP 4.
Ground the enclosure by solidly connecting one No.
6AWG wire (or wires of equiva lent cross-sectional
area) to the ground lug on the back of the enclosure.
See Figure 6. Sol idly connect the other end of the
enclosure ground wire to the switch ground wire(s).
Figure 6. The enclosure ground lug is on the pole side.
