Inverters
Mark: The pin definitions of RS485 communication interface
are as follows:
Pin1
Pin6
Pin1：GND； Pin2：+5V； Pin3：RS+；
Pin4：RS-； Pin5：GND； Pin6：GND
⑶ Basic Wiring Diagram
The whole wiring of the inverter is divided into two parts,
main circuit terminal connections and control circuit terminal
connections. Users can see the main circuit terminals, and the
control circuit terminals after removing the outer cover. The
terminals must be connected correctly as the following wiring
circuit diagrams.
