RS422
Fronius
Inverter types
IG-Plus and IG-TL
At Fronius, two RS485 inputs of the e.manager nD are used. Only the RS485-III interface can then still be used to connect other inverter manufacturers!
RS422 connection
Connect the inverters to each other with a patch cable. Make sure that you always connect OUT with IN.
At the last inverter, please connect wires 3 and 4, as well as wires 5 and 6 with each other.
Disconnect the cable from the last inverter to the e.manager and connect the individual wires to the e.manager as follows.
e.manager RS485 I Terminal A <=> PIN 3 (green-white)
e.manager RS485 I Terminal B <=> PIN 6 (green)
e.manager RS485 II Terminal A <=> PIN 4 (blue)
e.manager RS485 II Terminal B <=> PIN 5 (blue-white)
Optionally you can also connect a RS422 to RS485 converter in between. This converter can then ONLY be connected to RS485-II or RS485-III.

RS485 Modbus
Fronius
Inverter types
All, one inverter must have a data manager. Max. 10 inverters.
For Modbus use, a Datamager must be installed in a WR.
RS485 connection
Connect the inverters to each other with a patch cable. Make sure that you always connect OUT with IN.
At the last inverter, please connect wires 3 and 4, as well as wires 5 and 6 with each other.
Connect the data manager from the last inverter to the e.manager.
Inverter configuration
Leave all settings unchanged (protocol: Solarnet).
Connect to the Datamanager and activate the Modbus.
