Frequently Asked Questions

1. What does the Connex Waterproof Switch Panel 4 Plus Voltmeter do?
   It gives you four illuminated switches to control accessories and a built-in digital voltmeter to monitor your battery voltage.
2. Is it waterproof?
   Yes. The front panel is sealed and splash-resistant, which makes it suitable for outdoor and marine use.
3. What is the voltmeter for?
   It shows your real time battery voltage so you can keep an eye on battery health and prevent unexpected power loss.
4. What can I run from the switches?
   LED lights, water pumps, radios, fans, small appliances and most 12V accessories.
5. How do I wire it?
   Connect each switch to its accessory and the panel to a fused 12V supply.
6. Can I hardwire it into my 4WD or caravan system?
   Yes. It is designed for permanent installations in campers, boats, caravans and off-grid setups.
7. Is the display lit?
   Yes. The digital voltmeter is backlit so the reading is easy to see in low light.
8. Does it drain the battery?
   The display uses very low power and is unlikely to drain a healthy battery.
9. Is it easy to install?
   Yes. Mount the panel, connect to a fused power supply and wire each accessory to its switch.
10. Can it handle marine environments?
    Yes. It uses corrosion-resistant materials that suit marine and outdoor applications.

Tips & Tricks

• Mount the panel somewhere you can clearly see the voltmeter at a glance.
• Use heat shrink and waterproof connectors for boats or wet areas.
• Keep the main feed fused to protect your wiring and accessories.
• If your voltage drops below normal levels, turn off high draw loads to preserve battery health.
• Label the switches for easy identification in the dark.
• Use suitable cable gauge if powering multiple accessories to prevent voltage drop.
• Clean the display occasionally to keep the reading visible and clear.

Installation Steps

1. Prepare the cut-out:
   Mark the required dimensions (approx. 165 mm × 68 mm) and cut the opening. Deburr edges and test-fit the panel.
2. Mount the panel:
   Use the supplied stainless steel screws to secure the panel in place. Avoid overtightening to preserve gasket sealing.
3. Wiring connections:
   • Connect the main 12 V positive feed to the panel’s input terminal.
   • Connect the main negative (ground) to a common grounding bar.
   • Run output wires from each switch to the corresponding load or accessory.
   • If equipped with a voltmeter or socket, follow the wiring diagram (usually shares positive input).
4. Insert fuses:
   Fit the correct-rated blade fuses for each circuit, matching load requirements.
5. Test operation:
   After securing the front cover, power the system and test each switch. Confirm LEDs light up when active and that connected devices function properly.
6. Secure wiring:
   Use cable ties and clips to prevent movement, vibration, or chafing. Protect wire entry points with rubber grommets.
