unscrew the cover and plug the other end of
the CAN communication cable to the CAN
connector. Tighten the cover which is set on the
cable.

Inverter and BMS. Please pay attention to
connect the charging cables (+,-) to the
correct port on both Inverter and BMS.
2. Connect the negative cable (-) (B)to the port
