Approvals, standards and guidelines
9.1 EMC limit classes
Please note that EMC limit classes are only reached if the standard switching frequency of 8 kHz is com
-
plied with.
Depending on the installation material used and/or extreme ambient conditions, it might be necessary to
use additional sheath wave filters (ferrite rings). If the device is wall-mounted, the length (max. 3 m) of the
shielded motor cables (with large surfaces at both ends) may not exceed the permissible limits.
Wiring suitable for EMC also requires that EMC glands be used on both sides (frequency converter and
motor).

INFORMATION
In a residential environment this product can cause high-frequency interference requiring interfer-
ence suppression measures.
9.2 Classification according to IEC/EN 61800-3
The generic standard defines test procedures and severity levels for every environment in the frequency
converter category which have to be complied with.
Definition of environment
First environment (residential, commercial and industrial area):
All “areas” which 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 environments with their own supply network separated from the public low-voltage supply by a
transformer.
9.3 Standards and directives
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 61800-5-1:2003)
