Maximum Output Current For Data Communication And The 12 V Signaling Output; Connecting Data Communication Cables To Inverters - Fronius IG-TL 3.0 Operating Instructions Manual

External communication (Solar Net) takes place in the inverter via the data communication
rack. The data communication rack is equipped with two RS 422 interfaces - an input and
an output.
RJ45 plug connectors are used to establish the connection.
Maximum output The maximum total output current for data communication and the 12 V signaling output is
current for data 500 mA, which can be divided up as follows:
