An isolating transformer must have the following properties:
● The transformer secondary must be in the star connection (a delta connection is not
permissible!).
● The neutral conductor must be brought out. It must be connected with the PE of the line
filter, line reactor and S120 Combi (infeed).
: If the neutral conductor is not brought out and/or not connected, then all of the
restrictions of an IT line supply apply!
