432065 PRODUCT PERFORMANCE CHARACTERISTICS DC input 24V AC output 220V/50Hz Have a fully functional protective circuit:Short circuit、Overrating、Overload overtemperature 、inverse . protection  Conversion efficiency up to 90% Low interference technology Soft start function Same size， light weight， faint noise ，free maintenance Features High converting  efficiency Under voltage shutdown protection Over voltage shutdown protection Latest soft-start technique Overload protection Overheat protection Alloy aluminium case Usage method 1.Place the power switches of the inverter and the AC device on the OFF position. 2.Connect properly to DC power source in compliance with the rating input voltage. 3.Plug the cord of the AC device in the output socket of the inverter. 4.Turning the switch of inverter on (the switch indicator gives light)， then that of the AC device， this AC device can be used now as under the power supply. Warning Please treat the outlet of the inverter with the same respect as that of any household power . Don’t place any article on/over the inverter when operating . Keep the circulation of air around it. It gets so hot after working at a full load for a long time that it may hurt you if you touch it. Avoid the reach of children Avoid using it at a place that is wet ， high temperature ， flammable or explosive. Note: When the red light is flashing may be caused by the following improper operations: 1.The battery voltage is not correct. 2.Short circuit: The line connected is error. 3.Overload : The electric devices voltage is too high. When the machine gives out a lot of noise may be caused by the following problems: 1.Overheat 2.Overload 3.Overvoltage 4.Others
