2. Wire the remaining inverters to each other according to the manufacturer's specifications.
3. Terminate the last inverter according to the inverter instructions.
4. 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 inverter.
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 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.
