EMC-compatible installation

5.3.1

Motor cable

The applicable standard for interference emissions is EN 61000-6-3. Compliance with this standard is
achieved through the use of an unscreened motor feed cable.
5.3.2

Control cables

Pay attention to sufficient distance from powerlines and motor wires to prevent interferences. The
control cable may not be longer than 30 m. Screened control cables must be used when the cable
length is longer than 20 m. When using a shielded cable connect the shielding to one side only, i.e.
only to the control unit with the protective ground (keep cable short and with as little inductance as
possible!).
5.3.3 Harmonics current for devices ≥ 4 and ≤ 16 A
According to EN 61000-3-2 these devices are to be classified as "professional" devices.
Connection to a low voltage supply (public networks) is allowed insofar as this has been clarified with
the respective energy supply company responsible.
5.3.4 Harmonics current and line impedance for devices > 16 A and ≤ 75 A
Extract from EN 61000-3-12, valid for equipments with rated current > 16 A and ≤ 75 A, connected to
public low-voltage systems.
This equipment complies with IEC 61000-3-12 provided that the short-circuit power S
