  • Page 2: Warning And Safety Instructions

    1. Over discharge risk. Ensure that the Turn OFF voltage is suitable for the specications provided by the battery manufacturer. 2. The SBI12-BLD is designed for controlling loads from an Auxiliary battery. Using the SBI12-BLD to isolate from a start battery will result in a state of charge too low to start the vehicle.

    WARNING & SAFETY INSTRUCTIONS 3. The SBI12-BLD will achieve best results when proper battery maintenance is regularly performed. This includes but is not limited to checking water and specic gravity levels of the battery. Refer to the battery manufacturers manual for more details.
  • Page 4 (earth when loads should be on, no earth when loads should be off), and there is additional voltage thresholds monitored by the SBI12-BLD to ensure reliable solenoid engagement. The Isolator monitors the auxiliary battery and when this drops below the Turn OFF voltage, the solenoid will open, disconnecting the load.

  • Page 5: Installation Instructions

    INSTALLATION INSTRUCTIONS 1. Mount the SBI12-BLD securely in a convenient location near the auxiliary battery bank. Do not mount in direct engine heat. 2. Install in the order described below: • Ground Connection. Connect the SBI12-BLD ground terminal to the BMS Load Disconnect terminal.

  • Page 8: Frequently Asked Questions

    Answer: This can occur for one of two reasons. Firstly, switching an excessively large load which would drop the battery to below its lower voltage limit and causing the SBI12-BLD to turn off. After turning off the load, the battery would recover in voltage; If the battery voltage climbs higher than the turn on threshold, the SBI12-BLD would turn the loads back on.
