INSTALLATION 1. Ensure auxiliary battery negative post is properly grounded to vehicle. 5. 2. Using the appropriate cable and fuse/circuit breaker, connect the terminal marked 'main' to the positive terminal of the main or starting battery. 3.

SETTINGS There are no correct or incorrect settings for the battery isolator, the set points are entirely dependent on the user and the required end result. The main objectives are to protect your main cranking battery from being overly discharged (disengaging at a reasonable voltage) and, under extreme circumstances being able to utilise charge in the auxiliary battery to start a vehicle if the main battery has failed. To enter the programming mode please follow these instructions: PROGRAM INSTRUCTIONS 1.
OPERATION Once your battery isolator is installed and the set points are programmed it is operational at all times. All functions can be visually checked by either the remote indicator or the LED readout on the unit. 6 DISPLAY REMOTE DESCRIPTION b1 Off Main battery is connected to the main stud (only occurs when connecting the battery isolator to the vehicle). b2 Off Auxiliary battery is connected to aux stud (only occurs when connecting the battery isolator to the vehicle).
REVERSE CHARGING SYSTEM In a number of situations, the auxiliary battery may need to be connected to a solar input or additional charging system. The battery isolator will recognise that the auxiliary battery is receiving charge and if the main battery is below 12.8 volts and the auxiliary battery is above 13.36 volts and receiving a charge, the battery isolator will open the circuit and allow the auxiliary battery to charge the main battery.
