2.0 Installation
2.1 Pole-mounted version, continued
2.1.2 Installation on Wooden Pole
Never transport the unit with batteries installed. Transporting the unit with installed batteries may
cause injury to installer and/or damage to enclosure and installed equipment. Install batteries after
transporting the unit to the installation site and securing it to the pole.
Alpha recommends positioning enclosure on the opposite side of the pole from oncoming traffi c.
This can reduce the danger caused by falling equipment in the event that a pole is struck by an
automobile. Mounting bolts must go completely through the wooden pole. Secure the bolts from
the back with a large washer and nut.
The majority of poles are the property of the local Utility. Before installing an enclosure, the location and
method of mounting must be approved by the Utility. Most codes require the base of the enclosure to be
located a minimum height from the ground. Always verify height restrictions before proceeding.
Verify the following items are present before installation:
Pole mounting kit (Alpha p/n 746-032-20) qty. 1
Pole mounting brackets (Alpha p/n 744-670-20) qty 2
Materials: (Customer supplied)
• 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)
Tools: (Customer supplied)
• Auger or drill for boring 3/4" diameter holes in the wooden pole
• Mallet or hammer
• Assorted sockets
Procedure:
1. Unpack the enclosure and galvanized brackets; turn the enclosure facedown on a soft surface.
2. 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 using a supplied 3/8" x 3/4" hex
bolt. This prepositions the lower mounting bracket, enabling the installer to accurately locate the
placement of the lower mounting hole.
3. 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" machine bolt, washer and nut. Do not
fully tighten the bolt at this time.
4. Position the enclosure on the upper mounting bracket. It may be necessary to slightly rock the
enclosure and pull downward to properly seat it on the bracket. Center the enclosure on the pole.
5. Mark the hole for the lower mounting bracket. Lift the enclosure off the top bracket and drill the
lower hole. Spacing between holes for enclosures is 16.25" on center.
6. 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.
7. The enclosure is now ready for the utility connection (per Section 2.5, Connecting Utility Power),
power module, batteries and nodes.
