4.2. Passos d'instal·lació

1. Preparar el vehicle: Ensure the vehicle is turned off and disconnect both the main starting battery and the auxiliary battery.
2. Mount the Isolator: Choose a suitable, secure location for the Smart Battery Isolator. It should be protected from direct water spray and excessive heat. The reinforced nylon housing provides anti-high and low temperature resistance.
3. Connect Main Battery: Connect the positive terminal of your main starting battery to one of the main terminals on the isolator using the provided red battery cable and appropriate terminals/lugs. Ensure a fuse holder is installed in line for protection.
4. Connect Auxiliary Battery: Connect the positive terminal of your auxiliary battery to the other main terminal on the isolator using the remaining red battery cable and appropriate terminals/lugs. Again, ensure a fuse holder is installed in line.
5. Connexió a terra: Connect the black ground battery cable from the isolator to a suitable chassis ground point.
6. Cablejat segur: Use the provided cable ties to neatly secure all wiring, preventing chafing or interference with moving parts. Apply heat shrink tubing to all exposed connections for insulation and protection. The thick pure copper core cables ensure efficient power transfer.
7. Reconnect Batteries: Once all connections are secure and verified, reconnect the main battery first, then the auxiliary battery.

5. Modes de funcionament

The DEWINNER Dual Battery Isolator operates in both automatic and manual modes, providing flexibility for different usage scenarios.

5.1. Automatic Mode (Default)

In automatic mode, the Voltage Sensitive Relay (VSR) intelligently manages the charging of both batteries:

• Connects at 13.3 Volts: When the main battery's voltage reaches 13.3 volts (indicating the alternator is charging), the VSR connects the auxiliary battery, allowing it to charge.
• Disconnects at 12.8 Volts: When the main battery's voltage drops below 12.8 volts (indicating the engine is off or not charging sufficiently), the VSR disconnects the auxiliary battery to prevent it from draining the main battery.

This ensures your primary battery is always charged and ready to start your vehicle, even if the auxiliary battery is heavily discharged by accessories.

5.2. Mode manual

The isolator features a manual override function. You can switch between automatic and manual modes as needed.

• Canvi de modes: A long press on the control button allows you to adjust the operating gear, switching between Auto and Manual modes.
• Encès/apagat manual: A single click on the button can turn the unit on or off, providing direct control over the relay connection.
