Safety Information
To prevent injury or damage to the inverter and connected devices, observe the following safety precautions:
- Ventilation: Ensure the inverter is placed in a well-ventilated area. Avoid direct sunlight or proximity to heat-sensitive materials to prevent overheating.
- Power Off Before Disconnecting: Always turn off the inverter's power switch and disconnect all electrical plugs before unplugging the inverter from its power source.
- Load Capacity: Do not exceed the inverter's continuous output power of 850 Watts. Overloading can damage the inverter and connected appliances.
- Dry Environment: Keep the inverter away from water, rain, and moisture.
- Proper Polarity: Connect the battery cables with correct polarity (red to positive, black to negative). Incorrect connection can cause severe damage.
- Children and Pets: Keep the inverter out of reach of children and pets.

Setup
Follow these steps to set up your power inverter:
- Placement: Choose a dry, cool, and well-ventilated location for the inverter. Ensure there is sufficient space around the unit for airflow, especially around the cooling fan.
- Battery Connection:
- Ensure the inverter's power switch is in the "OFF" position.
- Connect the red battery clip cable to the inverter's red DC Positive Terminal.
- Connect the black battery clip cable to the inverter's black DC Negative Terminal.
- Connect the other end of the red battery clip cable to the positive (+) terminal of your 12V battery.
- Connect the other end of the black battery clip cable to the negative (-) terminal of your 12V battery.
- Ensure all connections are secure and tight to prevent arcing or overheating.

Operating Instructions
Once the inverter is properly set up, follow these steps for operation:
- Power On: Flip the inverter's power switch to the "ON" position. The power indicator light should illuminate.
- Connect Devices: Plug your 110V AC appliances into the AC output sockets or USB devices into the USB ports.
- Monitor Load: Ensure the total wattage of all connected devices does not exceed 850 Watts. For devices with high startup surges (e.g., motors, refrigerators), ensure their surge wattage is within the inverter's peak capacity (3000W).
- Power Off: When finished, first turn off all connected appliances, then flip the inverter's power switch to the "OFF" position.
