Procedure
•
If you are making the cable yourself, connect the wires as shown in the following diagram:
Solar-Log™ terminal strip connector Terminal strip inside the inverter
Terminal PIN
► 1 (Data+) Pin 4 - 485+ (A)
► 4 (Data-) Pin 5 - 485- (B)
•
If only one inverter is to be connected, according to the manufacturer's handbook it must be termi-
nated.
•
Insert the terminal block connector into the Solar-Log™ RS485 socket.
Connect the inverters to each other
•
Connect with a shielded twisted-pair cable.
•
Where to connect: RJ45 socket (RS485(WiFi)), on the outside of the inverter.
Procedure
•
If you make the cable yourself, connect the wires as shown in the diagram:
Terminal strip inside the second inverter Terminal strip inside the second inverter
PIN PIN
Pin 4 - 485+ (A) Pin 4 - 485+ (A)
Pin 5 - 485- (B) Pin 5 - 485- (B)
•
Wire the remaining inverters to each other according to the manufacturer's specifications.
•
Terminate the last inverter according to the inverter instructions.
•
Insert the terminal block connector into the Solar-Log™ RS485 socket.
The RS485 sockets are each double connections so that the wiring can also be continued to the next inver-
ter.
Procedure
1. Connect the data cable to the free blocks A, B and G on inverter 1.
2. Connect the other end of the cable to the blocks A, B and G on inverter 2.
3. Connect the remaining inverters in the same way.
4. Terminate in the last inverter according to the manufacturer's instructions.
5. Close the inverter if no other inverters are to be connected.
6. Insert the terminal block connector into the Solar-Log™ RS485 socket.
Notes on inverter addresses
