9. When using the cable glands, tighten the swivel nut of each cable gland hand-tight. This will
secure the network cable in place.
10. If the inverter is installed outdoors, install overvoltage protection for all components in the
network.
11. Connect the other end of the network cable to the local network (e.g. via a router).

Procedure for connecting the multifunction relay

Procedure
1. Select for which operating mode you would like to use the
multifunction relay.
2. Connect to the multifunction relay according to the operat-
ing mode and the associated connection variant.
3. After commissioning the inverter, change the operating
mode of the multifunction relay, if necessary.

Installation Manual
Description
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.
The multifunction relay switches loads on or off, depending on the
power production of the PV system.
The multifunction relay switches loads on or off according to com-
mands transmitted by a communication product.
The multifunction relay controls the charging of the batteries depend-
ing on the power production of the PV system.
The multifunction relay controls an external fan, depending on the
temperature of the inverter.
The local grid operator may require that a signal is transmitted as
soon as the inverter connects to the utility grid. The multifunction re-
lay can be used to trigger this signal.
