4. Modified Power Inverter DF SUN 2500 Safety Information Read all the Cautions and Warnings before installing and using the power inverter The inverter must be properly installed The power inverter generates AC power from your DC supply such as batteries Treat the AC output just like you treat the AC output in your house Keep children away from the unit Do not connect the unit to AC distribution wiring Keep the unit away from water Do not allow water to drip or splash on to the power inverter Keep the unit in cool environments Keep out of direct sunlight and away from heating vents Keep the unit away from flammable material or in any location which may accumulate flammable fumes or gases With heavy use the unit will become warm and possibly hot So keep it away from any heat sensitive materials Make sure the opening to the vent holes is not blocked Do not open the unit High voltages are inside Use proper size wiring High power inverters can draw many amps from the DC source and can melt wires if not fused and sized properly Energy source Power Inverter is powered by batteries or DC suppliers For batteries or DC suppliers the output voltage must be in the prescriptive range of the inverter s input voltage and the output current should meet inverter s operation requirement The detail requirement depends on the power of loads If with the battery power supplying the using time
