• Mount securely using appropriate fasteners to prevent movement during vehicle operation.

4.2 Konnessjonijiet elettriċi

All connections must be made with appropriate cable gauges to handle the 70A current. Use high-quality crimp terminals and ensure secure connections.

1. Skonnettja Batteriji: Before making any connections, disconnect the negative terminals of both the starter battery and the service battery.
2. Input Connection (Starter Battery): Connect the input terminals (Start IN) of the VCC 1212-70 to the starter battery. Ensure an appropriate fuse (e.g., 80A-100A) is installed on the positive line as close to the starter battery as possible.
3. Output Connection (Service Battery): Connect the output terminals (Bord OUT) of the VCC 1212-70 to the service battery. Install an appropriate fuse (e.g., 80A-100A) is installed on the positive line as close to the service battery as possible.
4. Konnessjoni mal-art: Connect the ground terminals (Vs-, Vb-) to a common ground point or directly to the negative terminals of the respective batteries.
5. D+ Signal (Optional but Recommended): Connect the D+ terminal to the alternator's D+ signal or an ignition-switched positive source. This ensures the converter only operates when the engine is running.
6. Sensor tat-temperatura: Connect the included battery temperature sensor to the designated terminals (T). Mount the sensor directly on the service battery for accurate temperature readings. This is crucial for optimal charging of lead-acid batteries and protection of LiFePO4 batteries.

• No Charging / Power LED Off:
  • Check all input and output fuses. Replace if blown.
  • Iċċekkja li l-konnessjonijiet elettriċi kollha huma siguri u ħielsa mill-korrużjoni.
  • Ensure the starter battery voltage is sufficient (engine running).
  • Check the D+ signal connection (if used) for proper activation.
• Iċċarġjar bil-mod:
  • Confirm the correct battery type is selected on the converter.
  • Check cable gauges; undersized cables can lead to voltage drop and reduced charging current.
  • Ensure the temperature sensor is correctly installed on the service battery.
• Is-sħana żejda:
  • Ensure adequate ventilation around the unit. Clear any obstructions from cooling fins.
  • Verify the ambient temperature is within the operating range.
