Basic battery monitor installation.
3.6. Auxiliary electrical connections
In addition to the comprehensive monitoring of the main battery bank, a second parameter can be monitored. This can be one of
the following:
•
The voltage of a second battery, like a starter battery.
• The midpoint deviation of the battery bank.
• Battery temperature.
This chapter describes how to wire the +B2 terminal for the three above options.
3.6.1. Auxiliary connection for monitoring the voltage of a second battery
For use to monitor the voltage of a second battery, such as a starter or auxiliary battery.
Connection procedure:
1. Verify that the negative pole of the second battery is connected to the LOAD AND CHARGER side of the shunt.
2. Connect the ferrule pin of the second red cable with fuse to the shunt by pushing the pin into to the +B2 terminal.
3. Connect the M10 lug of the second red cable with fuse to the positive terminal of the second battery.
