4. Safety Information
Please read and understand all safety instructions before installing or operating this product. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Always disconnect power to the circuit before installation or maintenance.
- Ensure the input voltage (DC12V) matches your vehicle's electrical system.
- Do not exceed the maximum current ratings for each switch (5A, 10A, 15A).
- Install in a location protected from direct water exposure, despite the IP65 rating, to prolong product life.
- Consult a qualified electrician or marine technician if you are unsure about any part of the installation process.
- Keep children away from electrical components.
5. Setup and Installation
The Hyuduo 6-Gang Switch Panel is prewired for simplified installation. Follow these steps for proper setup:
- Choose Mounting Location: Select a flat, secure surface on your boat, yacht, RV, or bus that is easily accessible and provides sufficient space for the panel (approx. 183 x 90mm).
- Prepare Mounting Surface: Mark the outline of the panel and the screw holes. Use appropriate tools to cut an opening for the panel if flush mounting, and drill pilot holes for the mounting screws.
- Connect Wiring:
- Identify the main positive (+) and negative (-) power sources from your vehicle's 12V DC system.
- Connect the main red wire from the switch panel to your vehicle's positive (+) power source.
- Connect the main black wire from the switch panel to your vehicle's negative (-) ground.
- Each individual switch has prewired output terminals. Connect the positive (+) wire of the device you wish to control (e.g., lights, pump) to the corresponding output terminal of a switch. The negative (-) wire of the device should be connected to the vehicle's common ground.

- Apply Labeling Stickers: Use the provided sticker sheet to label each switch according to the function it controls (e.g., "Lights", "Pump", "GPS"). This aids in easy identification during operation.
- Mount the Panel: Place the sealing gasket around the panel opening (if applicable) and secure the switch panel to the mounting surface using the six provided screws. Ensure a snug fit to maintain the IP65 rating.
- Test Functionality: Reconnect power to the circuit and test each switch to ensure all connected devices operate correctly.
6. Operating Instructions
Operating the Hyuduo 6-Gang Prewired Marine Rocker Switch Panel is straightforward:
- Each rocker switch controls a single connected electrical device.
- To turn a device ON, press the top part of the corresponding rocker switch. The switch may illuminate to indicate it is active (if equipped with an indicator light).
- To turn a device OFF, press the bottom part of the corresponding rocker switch.
- Refer to the applied labeling stickers for quick identification of each switch's function.

7. Maintenance
Regular maintenance ensures the longevity and reliable performance of your switch panel:
- Cleaning: Periodically wipe the panel surface with a soft, damp cloth to remove dust and grime. Avoid abrasive cleaners or solvents that could damage the ABS material or markings.
- Inspection: Regularly check all wiring connections for tightness and signs of corrosion. Ensure the panel is securely mounted.
- Circuit Protection: The built-in circuit protector automatically resets. If a switch repeatedly trips, investigate the connected device for a short circuit or overload condition. Do not bypass the circuit protector.
- Environmental Protection: While IP65 rated, minimizing exposure to extreme conditions and direct water spray will extend the product's lifespan.
8. Troubleshooting
If you encounter issues with your Hyuduo 6-Gang Switch Panel, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Panel has no power / No switches work. | No power to the panel; loose main wiring connections; blown fuse in the vehicle's main circuit. | Check main positive and negative connections. Verify vehicle's 12V power supply. Inspect vehicle's main fuse. |
| A specific switch does not activate its device. | Loose connection to the device; faulty device; tripped circuit protector for that switch; faulty switch. | Check the wiring from the switch to the device. Test the device independently. If the circuit protector tripped, reduce load or fix short. If problem persists, the switch may be faulty. |
| Switch indicator light is off, but device works. | Faulty indicator light. | This is typically a minor issue and does not affect switch functionality. Replacement of the switch may be required if the indicator is desired. |
| Switch panel feels loose after installation. | Mounting screws are not tight; mounting surface is damaged. | Tighten mounting screws. If the surface is damaged, consider reinforcing it or relocating the panel. |
