Page 5: Safety First
Safety First WARNING! Shock hazard. Keep away from children. 1-1. The inverter generate the same potentially lethal AC power as a normal household wall outlet. Treat it as if you are using any other AC outlet. 1-2. Do not insert foreign objects into the inverter's AC outlet, fan or vent openings. 1-3. - Page 6 WARNING! Explosion hazard. 1-6. Do not use the inverter in the presence of flammable flumes or gases, such as in the bilge of a gasoline powered boat,or near a propane tanks. Do not use the inverter in an enclostireI containing automotive- type, lead-acid batteries.These batteries, unlike sealed batteries, emit explosive hy-drogen gas which can be ignited by sparks from electrical connection.

Page 8: Pure Sine Wave And Modified Sine Wave Inverter
Pure sine wave and modified sine wave inverters The inverter come in two types; pure sine wave power type and modified sine wave type. In the pure sine wave power inverter, the 230V AC output harmonically follows a smooth sine wave and is almost identical to normal mains electricity. -
Page 9: Guidelines
Guidelines Installation Conditions For safe and optimum performance, install the inverter in a location that is: 3-1-1. Dry - Do not expose to water drips or spray. 3-1-2. Cool - Operate only in ambient temperatures between 32F (0°C) and 104F (40°C). Keep away from heating vents or other heat producing equipment. -
Page 10: Working Principle
Guidelines Working Principle The inverter works in two stages.During the first stage,the DC to DC converter increases the DC input voltage from the power source(eg.A 12V battery) to 300V DC. In the second stage, the high voltage DC is converted to the watts you need (AC) using advanced power MOSFET tran- sistors or IGBT technology in a full bridge configuration. - Page 11 WARNING: Sparking may occur when connecting the unit to the battery, make sure no flammable fumes are present before making any connections. 3-2-2. Tighten the nut on each DC terminal by hand until it is snug. If the power more than 1800W, please use tools to tight up the screw.

Page 12: Battery`s Charge
Battery`s Charge We advise that please use deep cycle battery. If you hear the low voltage alarm, please stop the inverter immediately. When the battery is fully charged, the inverter can be used again. If you use the inverter in a car, then it would be necessary to run the engine of your car after each time you use the inverter. - Page 13 NOTICE: When connect to the appliances, remember to turn on the inverter before turn on the appliance. 3-3-3. If the audible alarm be ignored the inverter may be automatically shut down when the battery voltage drops to 9.8-10.2V / 19.6-20.4V, in order to prevent damage to the battery from excessive discharge.
