[Tips and precaution]:

1. This is a Modified Sine Wave Power Inverter, applied for DC 12 V,not for 24 V. Only connect it to 12 V battery.

2. The cooling fan is quiet and smart, will rotate at different speed according to the power load and temperature inside. 

    So don't worry if the fan doesn't work while the power load is low.

3. Be sure to connect the red cable to battery and inverter positive terminal, black cable to negative terminal of battery and inverter. 

    Wrongly connect the battery cables will cause damage to inverter and devices.

4. Do not leave the power inverter at the ON position for long time while your car is off.

5. Do not to power the inverter with a battery in charging .

6. Do not power electric appliances exceed 3500 watts.For some inductive loads ,Like refrigerator ,washing machine ,microwave oven,

    drill pump, chain saw, the power of the inverter should be kept at least 3 times that of electrical appliances.

7. Do not let the inverter into sunlight and water directly, keep it in cool and dry environment.
