Measuring voltage: 100 V AC or 400 V AC
The socket for the PC parameterization is situated
on the side of the unit. This is where the DPC
must be plugged in.

The synchronizing voltage must be connected three-
phase if the measuring voltage is connected three-
phase (N not connected). If the measuring voltage is
connected four-phase (L1-L2-L3-N), the synchronizing
voltage may be connected two-phase (L1-L2). L3 is
connected only for compensation and is not measured.
