1) Calculation according to IEC 60939-1, annex A, at rated voltage and 50 Hz. In practice are up to double values to be expected due to

the insulation resistance values of the used ceramic capacitors. For the medical version results computationally the value 0. In practice

are values 1 ... 2 mA to be expected due to the insulation resistance values of the used materials.
