Reference: Leakage current by inverter with model EMC filter enabled or disabled (reference data)
The table below lists the reference currents that may leak from the inverter when the internal EMC filter is enabled or disabled.
(Leakage current is in proportion to the voltage and frequency of input power.)
Note that the values listed in the table below indicate the reference currents leaking from the inverter alone. The values exclude
current leakage from external devices and equipment (e.g., power cables).
The drive in the range from 90kW to 160kW doesn't have the switch to activate and deactivate the internal EMC filter.They complies
EMC directive C3 level in standard condition.
