General Safety Precautions
To avoid injury:
• This enclosure and its hardware must only be serviced by authorized personnel.
• The 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 only be performed by authorized personnel.
• 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, fi re, or possible explosion.
• Avoid any contact with gelled or liquid emissions from valve-regulated lead-acid (VRLA) batteries.
Emissions contain dilute sulfuric acid that is harmful to the skin and eyes. Emissions are electrolytic, and
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.
To avoid damage:
• Prior to installation, verify the AC input voltage and frequency matches the rating of to the enclosure and
its equipment.
• 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 equipment is changed.
• Prior to installation, contact local utilities, building maintenance departments, and cable/piping locator
services to ensure that installation does not interfere with existing utility cables or 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.
