11. Ensure that the RJ45 plug is securely in place by pulling slightly on the cable.
12. Tighten the swivel nut on the cable gland hand-tight. This will secure the network cable in
place.
13. If the inverter is installed outdoors, install overvoltage protection for all components in the
network.
14. If you would like to integrate the inverter into a local network, connect the other end of the
network cable to the local network (e.g. via a router).

6.4.2 Operating Modes of the Multifunction Relay
Operating mode of multi-
function relay (Mlt.Op-
Mode)
Description
Fault indication (FltInd)
The multifunction relay controls a display device (e.g. a warning
light) which, depending on the type of connection, signals either an
error or the undisturbed operation of the inverter.
Self-consumption (SelfC-
smp)
The multifunction relay switches loads on or off, depending on the
power production of the PV system.
