® Smart Start Battery Isolator SBI12, SBI24 SBI212, SBI224 & dual sensing models
THE SMART START® SBI The Smart Start® SBI is a microprocessor controlled Smart Battery Isolator. The Smart Start® SBI is designed specifically for use in multi battery applications as a solenoid priority system to protect the start battery from being excessively discharged by auxiliary loads, whilst still allowing the auxiliary battery to supply non essential loads.
INSTALLATION INSTRUCTIONS 1. 2. • • • • • • • Mount the Smart Start® SBI securely in a convenient location near the start battery bank. Do not mount in direct engine heat. Install in the order described below: Make sure the auxiliary battery negative is properly grounded to the vehicle chassis (1) Ground Connection. Connect the Smart Start® SBI ground terminal to chassis ground. Remove any paint to ensure a good ground connection. Note: A good ground will ensure correct switching voltage.
STANDARD WIRING DIAGRAMS • Ensure adequately sized cable Start is used as per the chart on Terminal page 1. Ensure the auxiliary battery is properly grounded to a Override common chassis earth point. Wire (BLUE) Ensure the SBI ground wire is making good contact with the chassis ground point. When using fuses make sure that the fuse makes a good low resistance connection. Fuse/Circuit Breaker ratings are dependent on the type of installation and the size of the loads, refer to chart on page 1.
DUAL SENSING SMART START® SBI Dual Sensing Smart Start® SBIs or ‘D’ Series SBIs monitor both the start battery and the auxiliary. If the unit detects that either battery has exceeded 13.2V the isolator will be connected. The benefit of the dual control enables the user to charge the main battery from a solar panel or battery charger on the auxiliary battery. The SBI12D has the added feature of allowing charge both ways.
FREQUENTLY ASKED QUESTIONS Question: Why does the LED stay on after the vehicle is turned off? Answer: The LED stays on (indicating the Smart Start® is on & the batteries are linked) until the voltage drops to 12.7V (25.4V for SBI24). This can take a few minutes to many hours, depending on size & state of charge of the batteries as well as load on the batteries.
WARNING & SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS - This manual contains IMPORTANT SAFETY INSTRUCTIONS for the Smart Start® SBI battery isolator. DO NOT OPERATE THE ISOLATOR UNLESS YOU HAVE READ AND UNDERSTOOD THIS MANUAL AND THE ISOLATOR IS INSTALLED AS PER THESE INSTALLATION INSTRUCTIONS.
