Guidelines, norms and standards
This chapter contains information about electromagnetic compatibility (EMC), and
guidelines, norms and standards.
For binding information about the relevant drive control approvals, please refer to
the relevant type plate!
EMC limit classes
Please note that EMC limit classes are only reached if the standard switching fre-
quency (clocking frequency) of 8 kHz is complied with. Depending on the installa-
tion material used and/or extreme ambient conditions, it might be necessary to
use additional sheath wave filters (ferrite rings). If the device is mounted on the
wall, the length of the shielded motor cables (with large surfaces on both sides)
(max. 3 m) may not exceed the permitted limits.
Wiring suitable for EMC also requires that EMC screw connections be used on
both sides (drive control and motor).
NOTICE
In a residential environment, this product can cause high-frequency disrup-
tions that may require interference suppression measures.
Classification acc. to IEC/EN 61800-3
The generic standard defines test procedures and severity levels for every envi-
ronment in the drive control category; these have to be complied with.
Definition of environment
First environment (residential, commercial and industrial area):
All “areas” that are directly supplied by a public low-voltage connection, such as:
▪ Residential area, e.g. houses, apartments etc.
▪ Retail area, e.g. shops, supermarkets
▪ Public institutions, e.g. theatres, stations
▪ Outside areas, e.g. petrol stations and parking areas
▪ Light industry, e.g. workshops, laboratories, small businesses
Second environment (industry):
Industrial surroundings with their own supply network that is separated from the
public low-voltage supply by a transformer.
Standards and guidelines
The following specifically apply:
▪ Directive on Electromagnetic Compatibility (Directive 2004/108/EC of the
Council EN 61800-3:2004)
▪ Low Voltage Directive (Directive 2006/95/EC of the Council EN 61800-5-
