Battery Maintenance Guidelines
The battery maintenance instructions listed below are for reference only. Battery manufacturer’s instructions
for transportation, installation, storage or maintenance take precedence over these instructions.
• To prevent damage, inspect batteries every 3 months for:
Signs of battery cracking, leaking or swelling. The battery should be replaced immediately by
authorized personnel using a battery of the identical type and rating.
Signs of battery cable damage. Battery cable should be replaced immediately by Authorized Personnel
using replacement parts specifi ed by vendor.
Loose battery connection hardware. Refer to battery manufacturer’s documentation for the correct
torque and connection hardware for the application.
• Apply battery manufacturer’s specifi ed antioxidant compound on all exposed connections.
• Verify battery terminals and/or exposed connection hardware is not within 2 inches of a conductive
surface. Reposition batteries as necessary to maintain adequate clearance.
• Clean up any electrolyte (battery emission) in accordance with all federal, state, and local regulations or
codes.
• Proper venting of the enclosure is recommended. Follow the Battery Manufacturer’s approved
transportation and storage instructions.
• Always replace batteries with those of an identical type and rating. Never install old or untested batteries.
• Do not charge batteries in a sealed container. Each individual battery should have at least 0.5
inches of space between it and all surrounding surfaces to allow for convection cooling.
• All battery compartments must have adequate ventilation to prevent an accumulation of potentially
dangerous gas.
Recycling and Disposal Instructions
Spent or damaged batteries are considered environmentally unsafe. Always recycle used batteries or dispose
of the batteries in accordance with all federal, state and local regulations.
Electrical Safety
• Lethal voltages are present within the power supply and electrical boxes. Never assume that an electrical
connection or conductor is not energized. Check the circuit with a volt meter with respect to the grounded
portion of the enclosure (both AC and DC) prior to any installation or removal procedure.
• Always use the buddy system when working under hazardous conditions.
• A licensed electrician is required to install permanently wired equipment.
• Input voltages can range up to 240 VAC. Ensure that utility power is disabled before beginning installation
or removal.
• Ensure no liquids or wet clothes contact internal components.
• Hazardous electrically live parts inside this unit are energized from batteries even when the AC input
power is disconnected.
Mechanical Safety
• Keep hands and tools clear of fans. Fans are thermostatically controlled and will turn on automatically.
• Power supplies can reach extreme temperatures under load.
• Use caution around sheet metal components and sharp edges.

Battery Safety Notes
Chemical Hazards
Any gelled or liquid emissions from a valve-regulated lead-acid (VRLA) battery contain dilute sulfuric
acid, which is harmful to the skin and eyes. Emissions are electrolytic, and are electrically conductive and
corrosive.
To avoid injury:
• Servicing and connection of batteries shall be performed by, or under the direct supervision of, personnel
knowledgeable of batteries and the required safety precautions.
• Always wear eye protection, rubber gloves, and a protective vest when working near batteries. Remove
all metallic objects from hands and neck.
• Batteries produce explosive gases. Keep all open fl ames and sparks away from batteries.
• Use tools with insulated handles, do not rest any tools on top of batteries.
• Batteries contain or emit chemicals known to the State of California to cause cancer and birth defects
or other reproductive harm. Battery post terminals and related accessories contain lead and lead
compounds. Wash hands after handling (California Proposition 65).
• Wear protective clothing (insulated gloves, eye protection, etc.) whenever installing, maintaining,
servicing, or replacing batteries.
• If any battery emission contacts the skin, wash immediately and thoroughly with water. Follow your
company’s approved chemical exposure procedures.
• Neutralize any spilled battery emission with the special solution contained in an approved spill kit or with
a solution of one pound Bicarbonate of soda to one gallon of water. Report chemical spill using your
company’s spill reporting structure and seek medical attention if necessary.
• All battery compartments must have adequate ventilation to prevent an accumulation of potentially
dangerous gas.
• Prior to handling the batteries, touch a grounded metal object to dissipate any static charge that may have
developed on your body.
• Never use uninsulated tools or other conductive materials when installing, maintaining, servicing or
replacing batteries.
• Use special caution when connecting or adjusting battery cabling. An improperly connected battery cable
or an unconnected battery cable can make contact with an unintended surface that can result in arcing,
fi re, or possible explosion.
Lead-acid batteries contain dangerous voltages, currents and corrosive material. Battery
installation, maintenance, service and replacement must be performed only by authorized
personnel.

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.
Procedure:
Materials and tools needed (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)
Auger or drill for boring 3/4" diameter holes in the wooden pole
Mallet or hammer
Assorted sockets
Tape measure
