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
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).
• 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.

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.

3.2 GMR (Ground Mount) Installations
3.2.1 Pre-Installation
Before you can install the GMR series enclosure, you must decide on the location,
the type of mounting platform, and the connection and grounding options you will
use. Several mounting options are available for this enclosure. You can mount an
enclosure on a precast pad, pour-in-place pad using a template, or on an existing
concrete pad.
Things to consider:
Provide adequate room for service personnel to remove the doors for battery
•
installation and removal.
Wherever possible, select a site that is above the 100-year fl ood plain, and away
•
from residences.
Locate in the shade to minimize the effects of solar loading.
•
Locate in an area where airfl ow can be maximized.
•
Locate away from sprinkler systems or other sources of forced water.
•
Locate out of the prevailing wind to minimize the buildup of snow or accumulation
•
of wind-borne dust.
Avoid locating the enclosure where it will be an obstruction or will inhibit visibility.
•
Evaluate the soil conditions for suitability for the installation of the required
•
grounding system applicable to your particular installation.
Is utility power cabling run and terminated at the site?
•
NOTE:
The grounding method for a particular site will be dependent upon soil type, available space, local codes,
NEC (National Electric Code), and other site-specifi c characteristics.
ATTENTION:
It is the responsibility of the installer to meet the requirements of all applicable national and local codes. Alpha
Technologies assumes no responsibility or liability for failure of the installer to comply with the requirements of
all applicable local and national codes.

During normal operation, the FlexNet Fiber UPS (model ELPM300-48D) is powered
by 120VAC or 240VAC line input or 48VDC battery string. The UPS supplies 48VDC,
300W power to the GMT Fuse Module (p/n 747-218-20) and on to any customer-supplied equipment within the enclosure.
Output power is provided through the optional GMT Fuse Module. You can fi x the
module to the bottom arm of the swing rack, or to the left side of the fi xed equipment
rack in the GMR Series Enclosures. Four 4-position headers provide connection
points for ground and 48VDC output. Two of the headers are "Common" and the
other two headers allow for fused connections.
The wire connection is accomplished by stripping 1/4" of wire, inserting it into the appropriate header position and tightening in place with a .100" jeweler's screwdriver.
