probe to the ES771 module.
5 Connect another ES771A to the controller by connecting an additional 848652947 wire set from
the first module to the RJ45 receptacle on the second module.
Verify the number of modules (2) registered with the controller with command:

The system is now set to monitor both voltage and temperatures to support the batter string voltage
imbalance and slope thermal compensation features. Figure 16 depicts a reserve system where every
battery in the string being monitored for temperature. Again, the highest temperature measured will be
used for battery thermal management. Only one temperature probe is required for thermal compensation
features.
