Bushpower VSR Dual Battery Isolator

The Bushpower designed voltage sensitive relay isolates your auxiliary battery from your starter battery eliminating the possibility of fully discharging your starter battery.

Once the voltage of your starting battery rises above 13.3V (for 12V systems or 26.6V for 24V) the isolator engages to charge both batteries in parallel.

When the voltage of the starter battery drops below 12.8V (25.6V for 24V) the isolator disengages sending charge solely to the starting battery and the cycle starts again.

An LED at the top of the unit indicates when the isolator is operating.

The unit is hermetically sealed which means it is dust and water resistant so it is suitable for 4x4, marine and truck applications. No further sealing is required and studs have been tinned to prevent corrosion.

Installation Guide
1.   Locate a suitable position for the isolator in the engine bay or close to battery.

2.   Remove base plate from isolator.

3.   Connect battery cable to isolating studs (see wiring diagram in images). Ensure the cable is correctly sized to ensure good
      current flow to the battery reducing unwanted voltage drops to the isolator. An LED will illuminate when the isolator is in operation.

4.   Connect small earth wire to a suitable location, ensuring good earth connection, remove any dust or grime at
      the connection point.

5.   Once both battery cables are connected replace base plate (optional) and place the isolator housing at the desired
      locationand attach to vehicle.

6.   Connect to auxiliary batteries.

Your dual battery isolator module is now ready for operation.
