Communication Connector (CNJ11, CNJ12)
The CNJ11 and CNJ12 connectors are for communication with ESS controller or with other PCS in
parallel operation. Prepare two RJ45 connectors and six 1.32 mm
wires to the pin 1~2 and pin 4~7 of the RJ45 connector as the graphic and pin assignment below:

Note:
CNJ11 and CNJ12 are used for parallel operation more than one PCS. When multiple PCSs
are parallel operated, the network cable should be connected hand by hand, with CNJ11 or
CNJ12 of the first PCS is connected to upper controller and the terminal resistors should be
inserted to CNJ11 or CNJ12 of the last one.
