Tips & Tricks

Pre-Installation Planning

• Mount the panel in an easy to reach location so you can operate switches while standing or seated.
• Always use a fused power supply to protect your accessories.
• Label each circuit so you can quickly identify what is connected.
• Use heat shrink connectors or waterproof terminals in marine or wet areas.
• Test each accessory after installation to confirm correct switch assignment.
•  
• Keep wiring neatly routed and secured to prevent vibration damage.

Installation Steps

1. Cut-out: Use a template or measure panel dimensions (approx. 165 × 68 mm). Cut the opening, smooth the edges, and test-fit the panel.
2. Mounting: Fix the panel securely with the supplied stainless-steel screws. Do not overtighten.
3. Wiring:
   • Connect the main positive supply to the panel input.
   • Route negative (ground) to a common ground or negative bus bar.
   • Connect each switch output to its respective load.
   • Ensure all connections are tight, crimped properly, and insulated.
4. Voltmeter / Accessory Wiring: If your panel includes a voltmeter or socket, wire it according to the diagram (usually shares the main 12 V input).
5. Insert Fuses: Fit the correct blade fuses for each circuit according to your device’s current draw.
6. Final Assembly: Clip on the nylon front cover to protect fuses and screws.
7. Testing: Power up the system and test each switch. Check that LEDs light correctly and that devices operate normally.

Maintenance Tips

1. Use marine-grade, tinned copper wiring and sealed connectors to prevent corrosion.
2. Apply dielectric grease to terminals in damp environments.
3. Inspect fuses, boots, and connectors periodically for signs of wear or corrosion.
4. Keep spare fuses nearby for quick replacements.
5. Clean the panel surface occasionally with a soft, dry cloth.
6. Regularly monitor the voltmeter to check battery or system voltage.
