Leakage current of EMC-filter built-in type of inverters
An EMC filter uses grounding capacitors for noise suppression which increase leakage current. When using an
EMC-filter built-in type of inverters, therefore, check whether there is no problem with electrical systems.
Three-Phase PDS (Power Drive System) with touch currents
≥
3.5 mA AC or
≥
10 mA DC
As the touch current (leakage current) of inverters with EMC-filter is relatively high, it is of essential importance
to always assure a reliable connection to Protective Earth (PE).
In Table G-3, for the inverter types whose leakage currents are equal to or exceed the critical value of 3.5 mA
AC or 10 mA DC (IEC 61800-5-1), the minimum cross sectional area of the PE-conductor should be:
• 10 mm
2
(Cu-conductors)
• 16 mm
2
(Al-conductors)
An electric shock could occur.
