3.4 Auxiliary electrical connections
In addition to the comprehensive monitoring of the main battery bank, the SmartShunt can monitor a second
parameter. This can be the voltage of a second battery (starter battery), the midpoint deviation of a battery bank
or the battery temperature. To allow for this, the SmartShunt is equipped with a second monitoring input, the Aux
input. This chapter describes how to wire the Aux input for the three possible configurable options.
3.4.1
Aux connection for monitoring the voltage of a second battery
The Aux connection can be used to monitor the voltage of a second battery, such as a starter battery.
This is how to make the connections:
• Connect the M8 terminal of
the red cable with fuse to the
positive terminal of the
second battery.
• Connect the ferrule pin of the
red cable with fuse to the
SmartShunt by pushing the
pin into to the “Aux” terminal.
• Make sure that the negative
of the main battery and the
negative of the second
battery are common.
3.4.2
Aux connection for monitoring midpoint of a battery bank
The Aux connection can be used to monitor the midpoint voltage of a battery bank that consist out of multiple
batteries that are wired in series to create a 24 or 48V battery bank.
This is how to make the connections:
• Connect the M8 terminal of the red cable
with fuse to the positive terminal of the
midpoint.
• Connect the ferrule pin of the red cable with
fuse to the SmartShunt by pushing the pin
into to the “Aux” terminal.
For more information on midpoint monitoring see chapter 9. This chapter also provides information and wiring
diagrams on how to monitor the midpoint of battery banks that have been wired in series/parallel.
