Um Schäden am FU zu vermeiden, sollte die MOV-Verbindung zur
Erde bei Installation des FU in einem nicht geerdeten
Verteilungssystem, in dem die Nennspannung zwischen einer der
Phasen 125 % des Phase-Phase-Potenzials übersteigen könnten,
unterbrochen werden. Dazu sind die in den nachstehenden Abbildungen
aufgeführten Brücken zu entfernen.
1. Zum Lösen der Schraube, diese gegen den Uhrzeigersinn drehen.
2. Brücke abziehen und aus dem FU-Gehäuse enfernen.
3. Schraube fest ziehen.
Brückenposition
Wichtig: Schraube nach dem Entfernen der Brücke fest ziehen.
