2.3 Line filters
Caution
The line filters listed conduct a high leakage current via the PE conductor. Because of the
high leakage current of the line filters, a permanent PE connection of the line filter or
switching cabinet is required.
Measures according to EN 50178/94 Part 5.3.2.1 must be taken, e.g. PE conductor
(≥10 mm2 Cu) or laying of a second conductor, electrically parallel to the PE conductor, via
separate terminals. This conductor must also fully meet the requirements for PE conductors
according to IEC 364-5-543.
Note
If a high-potential test is conducted with alternating voltage in the system, the line filter must
be disconnected to obtain correct measurement results.
Caution
Only the line filters listed in Catalog NC Z must be used. Other line filters can lead to line
harmonics that can interfere with or damage other loads powered from the network.
