7.8 Leakage Current
Follow national and local codes regarding protective earthing of equipment where leakage current exceeds 3.5 mA.
Drive technology implies high frequency switching at high power. This high frequency switching generates a leakage current in the
ground connection.
The ground leakage current is made up of several contributions and depends on various system configurations, including:
l RFI filtering.
l Motor cable length.
l Motor cable shielding.
l Drive power.
