disassemble or service the unit can result in electrical hazard, including death from exposure to
high voltage. If you experience problems with the unit, discontinue use and Contact Technician.
11.When cleaning the inverter, please switch off power(unplug the inverter).Carefully clean with
dry cloth. Do not use wet cloth or cleanser.
12. Disconnect all AC and DC side connections before working on any circuits associated with the
inverter .Turning the ON/OFF switch on the inverter to off position may not entirely remote
dangerous voltage.
13.Keep away from children.
5.PROTECTION FEATURE
Inverter is equipped with numerous protection features to ensure safe operations.
Input Low Voltage Protection:
A: When battery voltage is below 10.5±0.2V, Buzzer sound 2 times, which indicates DC power
supply voltage is descending and batteries need to recharge.
B: When input voltage reach 10±0.2V, Buzzer sound 3 times and red light turn on. AC output
will be automatically shut off.
Input Over Voltage Protection
When input voltage reach 15.5±0.5V, Buzzer sound 4 times and red light turn on, the AC
output will be automatically shut off.
Short Circuit Protection
When short circuits occur, Buzzer sound 11 times and red light turn on, output will be shut off.
Overload Protection
When overload occur, Buzzer constantly sound and red light turn on, output will be shut off.
Reverse polarity protection: Fuse or MOSFET
a. Via Fuse: When battery terminals are reverse connected, fuse will be burned to protect
appliance.
b. Via MOSFET(Optional): When battery terminals are reverse connected, the inverter won’t work
until correct connect.
Over Temperature Protection
When heat sink temperature exceed 45℃，the inner cooling fan will automatically turn on to cool
the inverter. When inner temperature exceed 75℃，Buzzer sound 5 times and red light turn on,
