Main Function and Protections
1. Battery Low Voltage Alarm: When the voltage of battery is lower than normal voltage for a certain range, the inverter will beep to remind the user that the battery needs to be charged. The user should stop the electronic equipment and charge the battery as soon as possible.
2. Battery Low Voltage Protection: When the voltage of battery or power supply is too low, the inverter will shutdown automatically and stop output to avoid the damage of the battery or power supply. When the voltage is back to normal, the inverter returns to work automatically.
3. Battery over-voltage protection: Inverter will shut down automatically when the DC input voltage is more than the normal value for a certain range. Please note that it may damage the machine if the voltage is too high.
4. Over Heat Protection: If the inverter internal temperature or ambient temperature is too high, the inverter will go temperature protection automatically to ensure the safety of electrical equipment.
5. Over Load Protection: When power of the load connected exceeds the rated power (Watt) of inverter, the inverter will shut down automatically and stop output. It would recover and work normally after the removal of overload.
6. Short-circuit Protection: When the load is in short-circuit trouble, the inverter will shut down automatically and stop output. It would recover and work normally after the removal of short-circuits.
7. Earth leakage protection: inverter is made according to the national security leakage protection standards. When leakage of electricity occurs at the grounding terminals, leakage protection circuit will shut down the inverter to avoid the electric shocks.

Connection Diagram
Installation
1. Put the inverter switch on OFF position and then clip the battery clamps on the positive and negative terminals of the battery.
2. Note the positive and negative polarity: the red clip line "O"-shaped terminal should be connected with the red terminal of inverter, the black "O"-shaped terminal should be connected with the black terminals of inverter. Then the red clip connects the battery positive pole, the black clip connects the negative pole of the battery.
3. Turn on the inverter switch. If the light is green, the inverter works normally. If red, inverter is faulty. Please check the wires connection.
4. Put the plug of the electric equipment into the outlet of the inverter and turn on the switch. If the indicator light is green, the electric appliance works normally.
5. Operation procedure: When you use the inverter, please turn on the inverter firstly, and then turn on the electric appliances. When you stop using the inverter, please turn off the electric appliance firstly, and then turn off the inverter.
6. When the inverter is working, if the buzzer alarms and the light is red, it indicates that the inverter fails. The user should check the wires connection, DC input voltage and the peak power of loads, etc. After the fault is canceled, the inverter restarts automatically. And then turn off the inverter.

Warning
>> Do not put the inverter in the raining or humid place, it may cause electric shock.
>> Do not insert metals like naked wire into the output socket or inside the inverter through ventilation hole.Otherwise it may cause electric shock.
>> Do not put the inverter in the place where children can reach, it may cause injure and electric shock.
>> When the power inverter is used for a long time, it will be hot, please be careful.
>> Keep the inverter from flammable materials, fumes or gases when used.
> Proper cooling is necessary while operating.
> Please insure the inverter is put at "OFF" position when the vehicle is started, otherwise the large instant peak voltage will possibly damage the inverter or its connected electric appliance.
> Reliable connection of the inverter input and DC power output is necessary as the input current is considerable large when inverter is running.
Notice: the signals with ">>" are the operations which may cause the personal security.
the signals with ">" are the operations which may cause the machine damaging.
