How to install a Manager30 Battery Sensor Assembly

This information is applicable to the following products: 

• Manager30 Battery Sensor Assembly (BMS1230S3-SK)

REQUIRED TOOLS

• 17mm socket with ratchet spanner/wrench
• Phillips head screwdriver
• Torch/flashlight
• Drill
• 5.0mm drill bits

INSTALLATION GUIDES

RECOMMENDED INSTALLATION LOCATIONS

• Maximum 90cm/35" away from the auxiliary battery positive post
• Any interior location

To determine the cause of this short circuit, it will require diagnostic testing. REDARC recommends seeking the support of an installer.

Below is a list of the common causes and repairs.

HOW TO MOUNT YOUR SENSOR ASSEMBLY

1. Mark the holes to be drilled using the black plastic base mount as a template for the location of the holes. The holes are spaced with 14cm between the center of each hole. 

2. Drill holes for the M6 bolts or suitable screw dependant on surface type and ensure secure fitment. 

3. Attach the red temperature sensor to positive post of auxiliary battery (labelled REDARC BATT+).  

4. Connect an appropriately sized cable from auxiliary battery negative terminal to the bolt on “B NEG” side of the sensor.  

5. Connect a suitably sized cable from the Manager30 (Pin 3) to the bolt on “GND” side of sensor.

6. Connect a suitably sized cable from the bolt on “GND” side of sensor to the vehicle chassis ground. 

7. Connect the CANBus cable to the Manager30’s CAN port.  

WIRING BATTERIES IN PARALLEL

THINGS TO BE AWARE OF

• If the battery sensor assembly has been installed backwards, the readings on your display will be inverted (full charge can be shown going to load and not battery). 
• Avoid overtightening the red “BATT+” component to the battery positive terminal as it can damage the sensor. 
• Ensure there is no tension on the comms cables as this will damage the internals of the cabling. 
• There should only be one cable from your auxiliary battery negative to the “B NEG” post. Additional cable will provide incorrect readings to the Manager30.  
• We recommend installing the battery sensor assembly in an interior location.
