RFI filter
RFI filters have discharge currents to earth, which, in the event of
a fault (phase failure, load unbalance), can be higher than the
rated values. To avoid dangerous voltages, the filters must be
earthed before use.
For discharge currents f 3.5 mA, VDE 0160 and EN 60335 specify
that
• the protective conductor must have a cross-section f 10 mm
2
or
• a second protective conductor must be connected, or
• the continuity of the protective conductor must be monitored.
The table below lists radio interference filters with their matching
frequency inverters.

Radio interference filters DE6-LZ3-013-V4 to
DE6-LZ3-064-V4 can be mounted below (footprint
mounting) or – from DE6-LZ3-080-V4 – to the side of the
frequency inverter (book-type mounting).
