Um Schäden am FU zu vermeiden, sollten die MOV-Verbindungen
zur Erde bei Installation des FUs in einem nicht geerdeten
Verteilungssystem, in dem die Spannungen zwischen einer der
Phasen 125 % der Nenn-Leiter-/Leiter-Spannung 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.
