General Safety Precautions
To avoid injury:
• This enclosure and its associated hardware must be serviced only by authorized personnel.
• Enclosure must remain locked at all times, except when authorized service personnel are present.
• Remove all conductive jewelry or personal equipment prior to servicing equipment, parts,
connectors, wiring, or batteries.
• Read and follow all installation, equipment grounding, usage, and service instructions included in this
manual.
• Use proper lifting techniques whenever handling enclosure, equipment, parts, or batteries.
• Batteries contain dangerous voltages, currents and corrosive material. Battery installation,
maintenance, service and replacement must be performed by authorized personnel only.
• 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 result in arcing, a re, or possible explosion.
• A battery that shows signs of cracking, leaking or swelling must be replaced immediately by authorized
personnel using a battery of identical type and rating.
• Avoid any contact with gelled or liquid emissions from a valve-regulated lead-acid (VRLA) battery.
Emissions contain dilute sulfuric acid which is harmful to the skin and eyes. Emissions are electrolytic,
which are electrically conductive and are corrosive. Follow the Chemical Hazards notes if contact occurs.
• Do not smoke or introduce sparks in the vicinity of a battery.
• Under certain overcharging conditions, lead-acid batteries can vent a mixture of hydrogen gas that is
explosive. Proper venting of the enclosure is required.
• Follow the battery manufacturer’s approved transportation and storage instructions.
CAUTION!
Enclosure, equipment or parts may be damaged or cause damage if used or installed improperly.
To avoid damage:
• Prior to installation, verify that the AC input voltage to the enclosure and its equipment match with respect
to voltage and frequency.
• Prior to installation, verify that the output voltage from the enclosure or its equipment match the voltage
requirements of the connected equipment (load).
• Prior to installation, verify that the enclosure’s utility service panel is equipped with a properly rated circuit
breaker for use with the equipment inside. Refer to manufacturer’s recommendations.
• Review and upgrade utility service panel circuit breaker requirements whenever the equipment within the
enclosure is changed.
• Prior to installation, contact local utilities, local building maintenance departments, and cable/ piping
locator services to ensure that installation does not interfere with existing utility or building cables/piping.
• Do not exceed the output rating of equipment. Verify load requirements prior and during connection
process.
• Prior to handling the batteries, touch a grounded metal object to dissipate any static charge that may
have developed in your body.

Battery Safety
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 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.
• 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.
• 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,
re, or possible explosion.
• A battery showing signs of cracking, leaking, or swelling should be replaced immediately by Authorized
Personnel using a battery of identical type and rating.

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 specied 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 specied 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.
