The safe operating curves for dU/dt filters 130B2841 - 43 are shown in figures 16 and
17. It is assumed that the default cable types have a capacitance of 55 - 60 nF/100 m.
The values should be scaled in accordance with the actual cable capacitance. In case
of multiple cables, the capacitance is the sum of the cable capacitances.
