The infeed can be directly connected to a TN line supply for 3–ph. 400 V AC,
3–ph. 415 V AC, 3–ph. 480 V AC
For other voltage levels, the infeed can be connected through an autotrans-
former.

Symmetrical 4–conductor or 5–conductor three–phase line supply with
grounded neutral point with a protective and neutral conductor connector con-
nected at the neutral point which, depending on the line supply type, uses one
or several conductors.
For other line supply types
