RS485 terminal RS485 terminal
► 1 A (Data+) ► 2 A (Data+)
► 6 GND ► 6 GND
► 3 B (Data-) ► 4 B (Data-)
3. Connect terminals on inverter 1 to the corresponding terminals on inverter 2.
4. Connect the other inverters to each other in the same way.
5. Terminate the last inverter.
Set the DIP S1 switch for the terminal resistor to ON.
