insulation layer by about 8mm~10mm with a wire stripper.
 Connect one end of the cable with the insulation layer peeled off to RS485
COM port of SNE9610, RS485 A to the corresponding terminal of COM Port A and
RS485 A B to the corresponding terminal of COM Port B.
 Connect the other end of the cable with the insulation layer peeled off to the
inverter, RS485A to the terminal corresponding to RS485 Communication Port A of
the inverter, and RS485B to the terminal corresponding to RS485 communication port
B of the inverter.
 If SNE9610 is connected to multiple inverters at the same time, then the
hand-in-hand connection method can be adopted; there are two multiplexed RS485
communication interfaces on the inverter side to connect one of the RS485 interfaces
of the next inverter to another RS485 interface of the previous inverter. Note that the
interfaces shall correspond to each other (A to A, B to B). The number of machines
connected to a single COM port does not exceed 20.
4.2.2 Connection of Convergence Box
 When the convergence box is connected to SNE9610, it is recommended to use
the convergence box that meets the requirements of Modbus protocol.
 The communication cables from the convergence box are connected to COM
Port A and COM Port B of RS485 of SNE9610.
4.2.3 Connection of Box Transformer Measuring and
Controlling Device
 When the box transformer measuring and controlling device is connected to
SNE9610, it is recommended to use the communication protocol that meets the
requirements of Modbus protocol.
 The communication cables from the box transformer measuring and controlling
device are connected to COM Port A and COM Port B of RS485 of SNE9610.
