Technical information

Warning: High leakage current
As a result of the high switching frequencies, capacitances (parasitic and
integrated) with respect to ground may cause high leakage currents. This is the
reason that a permanent PE connection is required at the control cabinet and
at the line filter!
Measures according to EN 50178/94 Part 5.3.2.1 must be implemented, e.g.
1. Copper protective conductor with a minimum cross–section of 10 mm
2
should be connected, or
2. A second conductor should be connected in parallel with the protective
conductor through separate terminals.
This conductor must also fully meet the requirements for PE conductors
according to IEC 364–5–543.
