Manual - SmartShunt IP65
In order to be fully functional, the battery monitor needs to be configured; see the Configuration [8] chapter.
In case the battery monitor is going to be used to monitor a second battery, battery bank midpoint or battery temperature, see one
of the next 3 paragraphs on how to do this and then go to the Configuration [8] chapter.
Basic battery monitor installation.

3.5. 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 Aux terminal for the three above options.

3.5.1. 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 MINUS side of the shunt.
2. Connect the M10 lug of the grey "Aux" cable to the positive terminal of the second battery.

3.5.2. Auxiliary connection midpoint battery bank monitoring

For use with a battery bank that consists of multiple batteries that are wired in series or series/parallel to create a 24V or 48V
battery bank.
Connection procedure:
1. Connect the M10 lug of the grey "Aux" cable to the positive terminal of the midpoint.
For more information on midpoint monitoring and for additional diagrams on midpoint battery bank wiring see the Midpoint voltage
monitoring [32] chapter.
