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 240Vac. 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.

WARNING!

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 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 spills 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.

enclosure wall, preventing it from being knocked off of its shelf.
A Service Power Inserter is required in all enclosures. The primary function

of the SPI is to provide a connection point between the Alpha power supply
and the cable load. Additionally, the SPI can bypass the power supply
with a Service Power Supply. A 15A SPI is standard on PWE/PME Series
enclosures. The SPI-25 (25A) is for use with higher output current power
supplies.

The Solar Shield Kit maintains a cooler environment within the PWE-8
enclosure, prolonging the life of the batteries and the power supply. By
protecting the enclosure’s skin, the shield reduces the amount of solar
radiation absorbed by the enclosure (Note: For PWE-8 enclosure only).

The SHK offers protection against dirt and snow ingress. Alpha recom­mends the use of the ECF (Enclosure Cooling Fan) in enclosures equipped
with the SHK.

The Tamper Switch is a magnetic door switch that connects to status
monitoring equipment. Tamper Switches are available either as normally
open (NO) or normally closed (NC) and set off an alarm if triggered.

1.4 The Battery Integration Tray

The optional Battery Integration Tray (BIT) eliminates the need for battery slide trays, and
allows batteries to be individually installed or removed in PWE-3/6 enclosures. Each battery
is connected directly to the BIT using modular 50A connectors.

The BIT further improves wire management by pre-terminating connections for status
monitoring voltage sense leads and for the AlphaGuard battery balancer. This eliminates the
need to stack multiple wire terminations on each battery terminal, vastly simplifying battery
replacement. Battery preventative maintenance is virtually eliminated when the BIT is used
in conjunction with the new AlphaCell threaded-insert batteries, which do not have to be re­torqued.

Key Features:

• Improves enclosure wire management and reduces clutter

• Eliminates the need for sliding battery trays

• Reduces battery preventive maintenance costs

• Pre-wired for status monitoring and AlphaGuard, eliminating stacked leads

• Allows direct connection to the AlphaGen DC portable generator

• Factory installed option in PWE-3/6 enclosures

2.0 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.

• Alpha recommends that you position the enclosure on the opposite side of the pole from 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.

• System installation at >10º angle in not recommended.

ATTENTION:

The majority of poles belong to the local utility. Before you install an enclosure have both the location and

2.3 Connecting Utility Power

WARNING!

ONLY qualifi ed personal should connect the utility power. Power must be connected in
compliance with local electrical codes, and common safety practices must be observed.

ATTENTION:

• Connection to utility power must be approved by the local utility before installing the power supply.

• UL and NEC require that a service disconnect switch (UL listed) be provided by the installer and be
connected between the power source and the Alpha power supply.

• Connection to the power supply must include an appropriate service entrance weather head.

Utility power enters the enclosures through a 1-1/8" (28.6mm) opening in the bottom of the
PME series, and in the rear of the PWE series, or through an optional breaker box. The
enclosures accept a standard electrical fi tting.

A “high-magnetic” trip circuit breaker must be used in order to accommodate the high-inrush
currents normally associated with the start-up of ferroresonant transformers (400A, no-trip,
fi rst-half cycle). Do not replace this circuit breaker with a conventional service entrance circuit
breaker. Alpha recommends Square D circuit breakers for 120V installations, and HACR
(heating and air-conditioning) breakers for 240V installations. Alpha Technologies offers a
high-magnetic Square D circuit breaker and a BBX option (a UL Listed service entrance).

2.5 Battery Installation, continued

2.5.2 Battery Installation Procedure

WARNING!

To prevent arcing, never allow live battery cables to make contact with the enclosure.
Disconnect battery leads, or wrap the cable lugs with electrical tape.

CAUTION!

Threaded insert terminals require the use of 3/4" (19mm) bolts. The use of 1" (25.4mm) bolts will
seriously damage the battery. The only exception is the terminal with the large spacer for the in-line
fuse link. See section 2.5.5 for details.

NOTE:

In battery confi gurations made up of multiple battery strings, Alpha strongly recommends the use of in-line
fuses.

Procedure:

1. Place the batteries on the enclosure’s battery slide tray or battery shelf. The
correct arrangement of the batteries on the tray or shelves varies between
enclosure models. See the Figs. 2-26 through 2-31 for the correct battery
arrangement for each model. Leave a minimum of one inch of ventilation space
between the batteries.

2. To make identifi cation and record keeping easier, number and label the batteries.
Record each battery’s number and date code in the power supply maintenance
log.

3. Using the battery arrangement diagrams as a reference, connect the batteries
in series to achieve 36Vdc or 48Vdc. Refer to the diagrams for the location
of the optional in-line fuses. Torque terminal connections according to battery
recommendations (see battery label for AlphaCell batteries).

4. Check the polarity and voltage of the battery cable connector with a voltmeter
to verify correct connections. Do Not connect the battery string or strings to the
power supply at this time.

5. The power supply battery charger collects battery temperature compensation
information with a Remote Temperature Sensor (RTS) attached to one of the
batteries. Refer to the diagrams to determine which battery to attach the RTS
to. Attach the RTS about 1/3 of the way up from the battery’s base with a strong
adhesive tape. Route the RTS connector into the power supply compartment. Do
Not connect the RTS to the power supply at this time.

CAUTION!
Recheck the polarity and voltage of the battery cable connector before proceeding. Connecting

the battery string or strings to the power supply with incorrect polarity will cause a short-circuit, and
possible equipment damage.

6. Route the battery cable connector into the power supply compartment. Do Not
connect to the batteries to the power supply at this time.

2.6 Installing the XM Series 2 Power Supply

Installation Procedure:

1. Before installation, inspect the power supply for damage or loose connectors.

2. Place the XM Series 2 Power Supply in the lower-right compartment of PME enclosures,
or the upper-right compartment of PWE enclosures.

3. Switch the BATTERY BREAKER on the front of the power supply OFF. This prevents the
inverter from starting when the batteries are fi rst connected to the power supply. See Fig.
2-32.

CAUTION!
Check the polarity and voltage of the battery cable connector with a voltmeter before proceeding.

Connecting the battery string or strings to the power supply with incorrect polarity may cause a
short-circuit, and possible equipment damage. Check all battery connections for proper installation.
For complete battery installation procedures, see the “Battery Installation” section in this manual.

4. After verifying that the batteries, battery connections, and battery cables are connected
properly, plug the battery cable connector from the battery string or BIT into the power
supply’s BATTERY INPUT connector. The connector is keyed and color-coded to fi t in
only one direction. See Fig. 2-32.

5. Plug the Remote Temperature Sensor into the TEMP PROBE connector located on the
Inverter Module assembly on the front of the power supply. See Fig. 2-32.

6. If applicable, plug the optional Local/Remote Indicator lamp (LRI) cable into the LRI
connector. See Fig. 2-32.

7. If you are installing a Tamper Switch (TMPR SW), plug it into the 2-pin TMPR connector,
and plug the transponder cable into the transponder TMPR connection. See Fig. 2-32.

8. Plug the connector from the SPI into the power supply’s OUTPUT 1A. If the enclosure
has the optional AC Indicator (ACI) lamp, plug the connector from the SPI into the ACI
and the connector from the lamp into the power supply’s OUTPUT 1A. If the PIM option is
installed, connect a second SPI to OUTPUT 2. Make sure that the SPIs “ALT/ON” switch
is in the ON position. See Fig. 2-32.

9. If the installation includes a Module Retaining Cable option, attach the end of the cable to
the hole provided at the top, rear, center of the enclosure. Thread the cable through the
power supply handle and clip it back on itself.

10. The installation is complete. Do Not apply AC power to the power supply or switch
the Inverter Module’s BATTERY BREAKER ON. Refer to the power supply Operator’s
Manual for Start-up and Test procedures.

2.7 Cooling Fan Installation

NOTE:

• This procedure requires a service power supply (for example, an APP 9015S or APP 9022S) to maintain
power to the cable plant while fan is being installed.

• The fan kit for PWE-3, 4, 6, and 8 enclosures includes a fan assembly with a single fan. The PWE-9
and PWE-D36 enclosures’ kit includes a double fan assembly. The installation and wiring procedures,
however, are identical.

Tools Required:

• Phillips Screwdriver

Installation Procedure:

1. Attach the fan assembly to the two pre-drilled holes located in the upper, right, rear of
the enclosure using the two #6-32 x 3/8" (9.5mm) Phillips screws provided. Make sure
to orient the fan assembly so that the exposed fan is up and the fan guard is down, as
shown. Screw the screws in from the outside of the enclosure.

2. Plug one end of the fan’s Y cable into the SPI wire. Plug other end of the Y cable into the
power supply’s OUTPUT 1A.

3. Position thermostat away from power supply, as shown.

3.0 Pole-mount Enclosure Maintenance

Preventive Maintenance should be performed every three to six months.

Inspect the Pole-mount Enclosure

Perform a complete inspection of the Pole-mount Enclosure. Look for signs of rust and corrosion,
paying particular attention to the battery trays. Clean any rust or corrosion immediately.

Inspect the Mounting Brackets and Hardware

Carefully inspect the mounting bracket and mounting hardware. Look for signs of unusual wear and
loose hardware. Correct all mounting hardware failures immediately.

Check Battery Terminals and Connecting Wires

Care of the batteries is a critical step in any maintenance program. In addition to voltage checks,
visually inspect the batteries for signs of cracking, leaking, or swelling. To aid in quick identifi cation,
and tracking of voltages in the maintenance log, number the batteries inside the enclosure using
labels or masking tape. Batteries are temperature sensitive and susceptible to overcharging and
undercharging. Since batteries behave differently in the winter than in the summer, Alpha’s battery
chargers automatically compensate for changes in temperature by adjusting fl oat and accept charge
voltages. See the power supply's technical manual for complete preventive maintenance instructions.

Check each battery terminal and connection. Verify the posts are clean and the crimped connectors
are tight. Torque terminal connections to the manufacturer's recommendation. If there is an inline fuse
in the battery cable, check the fuse holder and fuse. Verify the terminals are properly protected with
an approved battery terminal corrosion inhibitor such as NCP-2. Record date of maintenance in the
maintenance log.

Check Battery Open Circuit Voltage

Switch the power supply’s BATTERY BREAKER to the OFF position. Disconnect the battery
connector from the Inverter Module and measure the individual voltage across each battery. The
difference between any battery in the string must not be greater than 0.3Vdc. Defective or marginal
batteries must be replaced with an identical type of battery. Record the unloaded battery voltages in
the maintenance log.

NOTE:

When the power supply’s BATTERY BREAKER is turned OFF, or the batteries are not connected, backup
power is not available.
