3. Safety Information
Observe the following safety precautions to prevent damage to the product, your vehicle, or personal injury:
- Voltage Compatibility: Ensure the connected device operates within the 12V to 24V DC range. Connecting to higher voltages can cause damage.
- Current Limit: Do not exceed the 15A current rating of the fuse. Overloading can blow the fuse or damage the wiring.
- Polarity: Always connect the red wire to the positive (+) terminal and the black wire to the negative (-) terminal of your device. Incorrect polarity can damage the device or the vehicle's electrical system.
- Secure Connections: Ensure all wire connections are secure and properly insulated to prevent short circuits.
- Water Exposure: While the product has an IP66 waterproof grade, avoid prolonged submersion or direct high-pressure water exposure to the bare leads.

4. Setup and Installation
This product is designed for custom wiring applications. Follow these steps for proper installation:
- Identify Device Requirements: Determine the voltage and current requirements of the device you intend to power. Ensure it does not exceed 24V DC and 15A.
- Prepare Leads: The red wire is positive (+), and the black wire is negative (-). Strip a small portion of insulation from the ends of the red and black leads.
- Connect to Device: Securely connect the red lead to the positive input of your device and the black lead to the negative input. This can be done via soldering, crimping with appropriate connectors, or using screw terminals, depending on your device. Ensure connections are robust and insulated to prevent short circuits.
- Verify Polarity: Double-check that the polarity is correct before plugging into a power source.
- Plug into Vehicle Socket: Insert the cigarette lighter plug firmly into your vehicle's 12V or 24V accessory power socket.

- Disconnect: To turn off power, simply pull the plug out of the vehicle's socket.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your Ovitar Cigarette Lighter Plug:
- Cleaning: Keep the plug and leads clean and free from dust or debris. Use a dry cloth for cleaning.
- Inspect Wiring: Periodically check the leads for any signs of wear, cuts, or damage to the insulation. Replace if damaged.
- Fuse Replacement: If the LED indicator does not light up and your device is not receiving power, the fuse may have blown. To replace the fuse:
- Unplug the unit from the vehicle's socket.
- Unscrew the tip of the cigarette lighter plug to access the fuse.
- Carefully remove the old fuse.
- Insert a new 15A, 250V, 6x30mm glass fuse.
- Screw the tip back on securely.
7. Troubleshooting
If you encounter issues with your Ovitar Cigarette Lighter Plug, refer to the following troubleshooting guide:
- No Power / LED Not Lit:
- Ensure the plug is fully inserted into the vehicle's cigarette lighter socket.
- Check the vehicle's cigarette lighter socket for power by testing with another known working device.
- Inspect the fuse within the plug. If blown, replace it with a new 15A fuse (refer to Maintenance section).
- Verify that the vehicle's ignition is on, as some sockets are only powered when the ignition is active.
- Device Not Working (LED is Lit):
- Check the wiring connections between the leads and your device for proper polarity and secure contact.
- Ensure your device is functioning correctly by testing it with another power source.
- Confirm your device's power requirements do not exceed the 15A limit of the plug.
