I tried connecting the Nuki Opener which must have resulted in blowing out a fuse in the house ringing system (no bell in any apartment in the house rang anymore). i disconnected the nuki opener, few days later some technician fixed the fuse or sth.
Want to try again but I don’t understand the 3 wires in G3 and 2 wires in N and I don’t want to make the same mistake (whatever it was that blow the fuse) again.
Could someone provide some help please ?
My apartment is like two apartments together and I have two doors, but there are no extra buttons anywhere. Maybe that has sth to do with the extra wires, but still I would not know what best to do about that regarding proper Opener Installation
