Figure 15 Schematic representation: connection of communications between MCU and battery module on SENEC.Home Li 2.5
9. Set the S <->M switch on the battery module to the M (Master) position.
This battery module is now the master for
further battery modules and controls the electronics and communication between further battery modules and the
MCU.
Figure 16 Battery module 1 assigned as the master
10. Now, depending on the configuration of your SENEC.Home Li storage unit, connect the further battery modules
with CAT 6 cables (figure 17 and associated table).
