If the master is the latest B3 battery with DIP switch:
5. If the battery communicates with the Schneider Conext Series, turn the master DIP
switch "#1" and "#3" to "ON".
6. When you setup the master DIP as setting 1~4,all the slaves keep the DIP 0000,no
need to change.
7. If the battery module is in communication with the ICC by 485 communication, turn
the master DIP switch "#1" and "#4" to "ON".
the DIP switch of slaves need to turn the “#4” to “ON” at the same time while the
master is setting 5.
8. If the energy storage system has only one B3, it is the master itself, and still follow the
above steps.

The DIP switch mode in case (7),1001 is only for ICC(a special communication device of
some no-communication inverter), it’s a special firmware in BMS,different from general
firmware,so if customers want to use ICC,please contact dyness to confirm.
