Sigurnosne informacije
Uvijek se pridržavajte sljedećih sigurnosnih mjera opreza tokom instalacije i rada:
- Disconnect all power sources before installation or maintenance.
- Nosite odgovarajuću ličnu zaštitnu opremu, uključujući zaštitne naočale i rukavice.
- Osigurajte odgovarajuću ventilaciju prilikom rada s baterijama.
- Avoid short circuits. Connect positive to positive and negative to negative terminals correctly.
- Do not immerse the isolator in water or expose it to excessive moisture.
- Konsultujte se sa kvalifikovanim stručnjakom ako niste sigurni u vezi sa bilo kojim koracima instalacije.
Postavljanje i instalacija
Follow these steps to properly install your VEVOR Dual Battery Isolator Kit:
1. Mounting the Isolator
Choose a dry, secure location near your main battery, away from direct heat or moving parts. Use the provided mounting screws to secure the isolator unit.

Operacija
Automatski način rada
The VSR automatically connects the main and auxiliary batteries for charging when the main battery voltage reaches 13.3V (or a user-defined "ON" voltage). Once the main battery is fully charged, the VSR will then allow the auxiliary battery to charge. When the engine is off and the main battery voltage drops below 12.8V (or a user-defined "OFF" voltage), the VSR disconnects the batteries to prevent the auxiliary battery from draining the main battery.

Ručni način rada
The isolator features a manual override mode. In case your main battery is depleted, you can manually engage the VSR to draw power from the auxiliary battery to assist in starting the vehicle. Refer to the LCD screen and control buttons for manual mode activation.

LCD ekran i postavke
The integrated LCD screen displays the real-time voltage of both batteries (BAT1 and BAT2) within a range of 4.5V-20V. Use the control buttons (ON, OFF, OK, UP, DOWN) to navigate menus and adjust settings such as "ON" voltage, "OFF" voltage, and delay time (3-60 seconds) to prevent frequent switching.

Održavanje
To ensure optimal performance and longevity of your VEVOR Dual Battery Isolator Kit:
- Regularly inspect all wiring connections for tightness and corrosion. Clean any corroded terminals.
- Keep the isolator unit clean and free from dust and debris.
- Povremeno provjeravajte zapreminu baterijetages to ensure proper charging and discharge cycles.
- Ensure the area around the isolator is well-ventilated.
Rješavanje problema
If you encounter issues with your dual battery isolator, consider the following:
- No voltage displej: Check power connections to the isolator. Ensure the main battery has sufficient charge.
- Auxiliary battery not charging: Verify all wiring connections are correct and secure. Check the "ON" voltage setting on the isolator; the main battery must reach this voltage before the auxiliary battery begins charging.
- Main battery draining: Ensure the "OFF" voltage setting is correctly configured to disconnect the batteries when the engine is off. Inspect for any parasitic draws on the auxiliary battery circuit.
- Frequent switching: Adjust the delay time setting on the isolator to prevent rapid connection/disconnection.
