2. If you are making the cable yourself, connect the wires as shown in the following diagram:
Terminal strip inside the inverter Terminal strip inside the inverter
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. If no further inverter is connected, terminate the inverter:
Set the DIP S1 switch for the terminal resistor to ON.
6. Insert the terminal block connector into the Solar-Log™ RS485 socket.
Allocate communication address
