Electrical Safety
WARNING
Hazardous voltages are present at the input of a power system. The DC output from
rectifiers and batteries, though not dangerous in voltage, has a high short-circuit current
capacity that may cause severe burns and electrical arcing.
Before working with any live battery or power system, the following precautions should be followed:
• Remove all metallic jewelry; e.g., watches, rings, eyeglasses, necklaces.
• Safety glasses with side shields must be worn at all times.
• Tools with insulated handles must be used.
Lethal voltages are present within a power system. Never assume that an electrical connection or conductor is not
energized. Check the circuit with a voltmeter with respect to the grounded portion of the enclosure (both AC and
DC) prior to any installation or removal procedure.
Do not work alone under hazardous conditions.
A licensed electrician is required to install permanently wired equipment.
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.
Battery Safety
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.
Use tools with insulated handles; do not rest 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).
WARNING
Follow battery manufacturer’s safety recommendations when working around battery
systems.
WARNING
Do not smoke or present an open flame when batteries (especially vented batteries) are on
charge. Batteries vent hydrogen gas when on charge, which creates an explosion hazard.
Batteries are hazardous to the environment and should be disposed of safely at a recycling facility. Consult the
battery manufacturer for recommended local authorized recyclers.
