![]() Connect all of the auxiliary loads (phone, lights, stereo, refrigerator, etc.) to the positive battery terminal of the auxiliary battery, use appropriate circuit protection fuses.Connect a length of cable (of suitable size, commonly 2 B&S) from the vehicle’s chassis or engine block to the negative terminal of the auxiliary battery as a ground cable (Earth), the isolator should now show a solid red ‘power’ LED.Reconnect the starting (main) battery’s negative cable (Earth), the isolator should now flash the red ‘power‘ LED.Connect the isolator’s ‘Earth’ wire (small black wire with ring terminal) to a suitable chassis bolt or screw, ensure the ring terminal will make a good electrical connection by removing any paint.Do not over-tighten the terminal studs on the electronic isolator. If using (Fused distribution terminal) the connection from the battery isolator should be made to main (large) fuse stud. The connection at the Auxiliary battery should be fused using a ‘Fused’ battery terminal or a 150 Amp fuse or circuit breaker mounted inline. Connect a length of cable from the ‘AUX’ (+) terminal on the isolator to the positive battery terminal of the auxiliary battery.Connect a length of cable from the ‘MAIN’ (+) terminal on the isolator to the positive battery terminal on the starting (main) battery.Note: To prevent the loss of vehicle electronic memories, radio presets & security codes, it is recommended that an “Electrical System Memory Protector” be used. Disconnect the negative battery cable (Earth) from the vehicle’s starting battery.Cable lugs should be crimped or soldered to the stripped battery cable and then protected with the heat shrink. To make the electrical connections, battery cables will need to be made to the correct length using cable lugs and heat shrink. Installation of the Battery Isolator– Connection 20mm² (4 B&S) for rear of vehicle / trailer mounted auxiliary batteries.14mm² (6 B&S) minimum for engine bay mounted auxiliary batteries (up to 3m).Auxiliary battery cradle & battery clamp.Charged auxiliary battery - Deep cycle recommended for most applications.Surge Protection - Provides surge protection for vehicles with electronic ignition/ management systems.Over-Current Protection – Protects the Isolator and charging system from over current damage, which could occur due to a short circuit in the wiring.Manual Override - If the starting battery is flattened and the auxiliary battery is charged, the electronic isolator allows the batteries to be manually paralleled to jumpstart the vehicle.Priority Charging for Starting Battery - Ensures that the starting battery is fully charged before connecting the auxiliary battery in parallel.It can be fitted to all 12V vehicle types. Easy to Install - The electronic isolator does not require any changes to the vehicle’s existing wiring.Batteries of differing voltages cannot be used. ![]() Battery Isolators are designed for negative ground alternator systems with batteries of the same nominal voltage.Follow all vehicle manufacturers’ instructions.Vehicles must be in “NEUTRAL ”or “PARK ”, park brakes “ON ”.BATTERIES PRODUCE EXPLOSIVE GASES - Ensure no sparks or flames are present.PLEASE READ THESE INSTRUCTIONS COMPLETELY PRIOR TO INSTALLATION.
