When connecting, do not press the insulation layer of the communication cable into terminal,
otherwise it may cause poor contact.
The RS485 communication wire must be routed separately from the input and output wires to
avoid interference with communication.
The baud rate of the inverter needs to be set through monitoring software WiseEnergy (for details,
please refer to the About-User Manual in WiseEnergy). The default baud rate is 9600. The
communication address of the inverter is set in binary mode through the dial switch SW1 (position
shown in Figure3-48) on the communication board, for example: when the dial switch SW1 is set to
"000001 (from left to right, ON is 1, OFF is 0)", which means the communication address of the inverter
is 1, and so on. If in doubt, please contact the manufacturer.
Figure3-48
Position of SW1
When multiple inverters are communicating, the dial switches SW3 on the communication boards of
first and last inverter on the communication link must be switched to the ON position.
