General information
The configuring of the infeed modules requires the performance data from the
Tables 6-9 and 6-10 and the following performance curves.

Note
When connected to line supplies with voltage fluctuations below the rated volta-
ge, the infeed should be overdimensioned corresponding to the above diagram
(Fig. 6-9), otherwise this can lead to failures or defects.

Note
With line filter, when the converter is operating at partial load, a capacitive pha-
se shift occurs.
As line supplies in companies generally have an inductive phase shift, this ca-
pacitive component has a compensating effect in this line supply.
