Fronius IG-TL 4.0 - Maximum Output Current for Data Communication and the 12 V Signaling Output; Connecting Data Communication Cables to Inverters

48
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.

IMPORTANTWhen networking several
DATCOM components, a terminating plug
must be placed on each free IN or OUT
connection of a DATCOM component.
IMPORTANT Close any unused openings
at the sealing insert using the appropriate
blanking plugs.
