BMS Communication Connector (CNJ13)
The CNJ13 connector is for communication between PCS and BMS. Communication with BMS is
handled in two ways, RS485/Modbus or CAN bus. RS485 requires three prepared AWG 16 wires
connected to pins 1 to 3 on the 6-pin connector from the accessory kit. For CAN bus, connect two
prepared AWG 16 wires to pins 5 and 6.
