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 specified 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 specified 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.
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.
031-295-B0-001, Rev. B (11/2018)
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.
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.
Battery Safety Notes
WARNING! GENERAL HAZARD
Lead-acid batteries contain dangerous voltages, currents and corrosive material. Battery installation, maintenance, service and replacement must be performed only by authorized personnel.
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 flames 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, fire, or possible explosion.

2.1.1 Installation on Wooden Pole
CAUTION!
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.
CAUTION!
Alpha recommends positioning enclosure on the opposite side of the pole from oncoming traffic. 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.
ATTENTION:
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
Procedure:
Materials: (Customer supplied)
• Two 5/8-16 machine bolts, length to suit pole
• Two flat washers for 5/8" bolts
• Two helical split lock washers for 5/8" bolts
• Two 5/8-16 hex nuts
Tools: (Customer supplied)
• Auger or drill for boring 3/4" diameter holes in the wooden pole
• Mallet or hammer
• Assorted socket wrenches
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 flanges 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, lock 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, lock washer and nut. Tighten both brackets until the flanges 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.
