4.2.2 Leakage currents
Calculated maximum leakage currents depending on voltage and frequency.
Rated input voltage / V Frequency / Hz Leakage current / mA
400 50 / 60 < 5
Table 8: Leakage currents
The specied leakage currents are calculated values according to DIN EN
60939-1. The real leakage currents may deviate from the calculated values
depending on the network conditions.
