Depending on the intended application of the multifunction relay, the procedure for connection will
vary (see Section 5.8.1 "Connection Options for the Multifunction Relay", page 24).
After commissioning, you must set the operating mode of the multifunction relay via a communication
product and, if necessary, make further settings relating to the operating mode (see Section 6.3
"Setting the Operating Mode of the Multifunction Relay", page 31).
Fan control (FanCtl) The multifunction relay controls an external fan depending on the
temperature of the inverter.
If the temperature of the inverter is 5°C higher than a specific
threshold set in the inverter, the fan starts automatically. If the
temperature of the inverter is 10°C below the set threshold, the
fan stops automatically.
Switching status grid relay
(GriSwCpy) The multifunction relay switches simultaneously with the grid relay
of the inverter and transmits a signal to the grid operator.
