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.
• Use tools with insulated handles, do not rest any tools on top of batteries.
• 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.
• 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.
Gas Safety
• Do not smoke or use any source of fl ame around gas lines. Propane and natural gas are extremely
fl ammable, and explosive at high concentrations. Large releases can create a fl ammable vapor cloud.
• Batteries produce explosive gases. Keep all open fl ames and sparks away from batteries.
• At high concentrations gas is an asphyxiant that displaces oxygen from the breathing atmosphere.
• Contact with liquid may cause skin and eye burns.
• 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.
