5. Safety Instructions

To ensure safe operation and prevent damage to the inverter or connected devices, please observe the following safety guidelines:

• Ventilation: Ensure adequate ventilation around the inverter. Do not block the cooling fan or vents.
• Environment: Avoid exposing the inverter to water, rain, snow, or excessive moisture. Do not operate in dusty environments or near flammable materials.
• Connection: Always connect the inverter to a 12V DC power source. Connecting to a 24V or higher DC source will damage the unit.
• Polarity: Ensure correct polarity when connecting to a battery (Red to Positive, Black to Negative). Incorrect connection can cause severe damage.
• Load Capacity: Do not exceed the inverter's rated continuous power output of 400W. The peak power is 800W, but continuous operation above 400W can lead to overheating and shutdown.
• Cigarette Lighter Limit: Be aware of your vehicle's cigarette lighter maximum power output, typically 120W-180W. For loads exceeding this, connect directly to the battery.
• Sensitive Devices: The pure sine wave output is suitable for sensitive electronics. However, always check the power requirements of your devices.
• Disassembly: Do not attempt to disassemble or modify the inverter. Refer all servicing to qualified personnel.
• Children: Keep the inverter out of reach of children.

6. Setup

The inverter can be connected in two ways: via the cigarette lighter socket or directly to a 12V battery.

6.1. Connecting via Cigarette Lighter Socket (for loads up to 150W)

1. Ensure the inverter's power switch is in the OFF position.
2. Insert the cigarette lighter adapter cable into the inverter's DC input terminals, ensuring correct polarity (red to positive, black to negative). Tighten the terminals securely.
3. Plug the cigarette lighter adapter into your vehicle's 12V cigarette lighter socket.
4. Turn on the inverter using the ON/OFF switch. The green indicator light will illuminate.

6.2. Connecting Directly to a 12V Battery (for loads up to 400W)

1. Ensure the inverter's power switch is in the OFF position.
2. Connect the red battery cable to the positive (+) terminal of the inverter and the black battery cable to the negative (-) terminal. Tighten the terminals securely.
3. Connect the other end of the red battery cable to the positive (+) terminal of your 12V battery.
4. Connect the other end of the black battery cable to the negative (-) terminal of your 12V battery.
5. Connect the ground cable from the inverter's ground screw to a suitable chassis ground point on your vehicle or a reliable earth ground.
6. Turn on the inverter using the ON/OFF switch. The green indicator light will illuminate.
