Tighten the plastic screw cap with rotation wrench(I).
2. C
onnect the RS485 communication
c
able (E) from BMS (
Ⅲ
) to the RS485 I
communication port (
Ⅱ
’) on the battery module. The communication ports are
marked in the following figure.
For 2~4 battery modules:
Follow the same steps as the above.
Then Connect RS485 II (
