General Safety Precautions
To avoid injury:
• Read and follow all installation, equipment grounding, usage, and service instructions included in this manual.
• Disconnect power before servicing.
• 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,
• 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
• Use special caution when connecting or adjusting battery cabling. An improperly connected battery cable or
an unconnected battery cable can result in arcing, a fire, 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.
Enclosure, equipment, or parts may be damaged (or cause damage) if installed or used 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.
• For continued protection against risk of fire, replace only with same type and rating of fuse.
