Unpack the enclosure and brackets; turn the enclosure facedown on a soft
surface.
Slide a bracket into the enclosure’s lower mounting strap. The bracket’s fl anges
must face away from the enclosure. Secure the bracket to the mounting strap us-
ing a supplied 3/8" x 3/4" hex bolt. This pre-positions the lower mounting bracket,
enabling you to accurately locate the placement of the lower mounting hole.
Mark the position for the upper mounting bracket on the utility pole. Drill a 3/4"
hole completely through the pole. Secure the bracket to the pole with a 5/8" ma-
chine bolt, washer and nut. Do not fully tighten the bolt at this time.
Position the enclosure on the upper mounting bracket. If necessary, slightly rock
the enclosure and pull downward to properly seat it on the bracket. Center the
enclosure on the pole.
Mark the hole for the lower mounting bracket. Lift the enclosure off the top brack-
et and drill the lower hole. Spacing between holes for enclosures is as follows:
PMR S-1 is 25 1/4" on center / PMR S-2 is 30.0" on center.
Slide the enclosure back into place over the top bracket. Align the lower bracket
with the hole and secure it with a 5/8" machine bolt, washer and nut. Tighten both
brackets until the fl anges seat into the wood.

3.0 Installation
CAUTION!
Never transport the unit with installed batteries. Doing so can cause injury or damage to the
enclosure and installed equipment. Install the batteries after you transport the unit to the site and
secure it to the pole.
CAUTION!
Alpha recommends that you position the enclosure on the opposite side of the pole from oncoming
traffi c. This reduces the danger of falling equipment in the event that a pole is struck by an
automobile. Mounting bolts must completely penetrate the wooden pole. Secure the bolts from the
back with a large washer and nut.
ATTENTION:
The majority of poles belong to the local utility. Before you install an enclosure have both the location and
mounting method approved by the utility. Because most codes require the enclosure to be located at a
minimum height from the ground, always verify local height restrictions before you proceed.

Two 5/8" diameter machine bolts, length to suit pole
Two 5/8" diameter zinc plated fl at washers
Two 5/8" diameter hex nuts (UNC thread)
