2.2 Pole-mount Installations

The APC- PM and APL-PM are designed to be mounted on wooden, steel, or

concrete poles. When used with wooden poles, mounting bolts that go completely

through the pole should be used. When used with concrete poles, an approved

mounting strap should be used. Most codes require the base of the enclosure to be

located at a minimum height from the ground. Always verify height restrictions

before proceeding.

NOTE: THE MAJORITY OF POLES ARE THE PROPERTY OF THE LOCAL

UTILITY. BEFORE INSTALLING AN ENCLOSURE, THE LOCATION AND THE

METHOD OF MOUNTING MUST BE APPROVED BY THE UTILITY.

NOTE: BEFORE INSTALLING THE MTA, ENSURE THAT ALL OPTIONS HAVE

BEEN INSTALLED AND PROPERLY CONNECTED.

2.2.1 Wooden Poles

Materials Required:

Two (2) 5/8” diameter machine bolts (UNC thread) SAE Grade 5 or better, length to

suit pole;

Four (4) 5/8” diameter zinc-plated flat washers;

Two (2) 5/8” diameter hex nuts (UNC thread).

Tools Required:

Auger or drill for boring 3/4” diameter holes through the wooden pole.

Associated sockets or wrenches.

Procedure:

1. Un-box the APC or APL and set the unit on its back (mounting bracket

down).

2. Loosen the enclosure’s front panel hold-down screw and tilt the cover

forward. Remove the cover by sliding (at the hinges) to the right.

3. Loosen the captive screw at the bottom of the units baseplate. Lift the

Modular transformer assembly up and off of the enclosure’s baseplate.

Set the MTA aside.

4. Mark the position for the upper mounting bolt on the utility pole. Drill a

3/4” hole completely through the pole.

5. Use the baseplate as a template. Align the upper hole in the baseplate

with the upper hole in the utility pole (from step 4). The spacing

between the marks should be 4.5” c-c. Drill the lower mounting hole.

6. Place a flat washer on each bolt and insert the mounting bolts through the

baseplate assembly and pole.

7. Secure both bolts using a 5/8” washer and nut. Tighten the nuts until the

flanges on the baseplate’s mounting bracket dig into the wood

approximately 1/4”.

8. Install the Modular Transformer Assembly (MTA) onto the baseplate, (see

section 2.9 MODULAR TRANSFORMER ASSEMBLY).
