Multifunction Relay SMA Solar Technology AG
3.2.1 Connection as Fault Indicator Contact
If you would like to operate a fault indicator, the relay must be connected so that position 2-3 is the
active position. You can also connect the multifunction relays of several inverters to one fault indicator.
The fault indicator displays as soon as one of the inverters shows an error.
If you would like to use the multifunction relay to indicate undisturbed operation, you must connect it
to all inverters in such a way that position 1-2 is the active position.
