1)
depending on ground current input at position 7, the function works either as ground fault protection (sensi-
tive input) or as ground short circuit protection (normal Ie input)
2)
only with sensitive input, Position 7=2
3)
only deliverable with position 6 = 1, 2 or 5
4)
only deliverable with position 6 = 3, 4 or 6 (3 x V)
