9 Guidelines, Norms and Standards
This chapter contains information about electromagnetic compatibility (EMC),
and guidelines, norms and standards.
9.1 EMV limit classes
Please note that EMV limit classes are only reached if the standard switching
frequency (clocking frequency) of 8 kHz is complied 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
mounted on the wall, the length of the screened motor cables (with large
surfaces on both sides) (max. 3 m) may not exceed the permitted limits.
Wiring suitable for EMV also requires that EMV screw connections be used on
both sides (drive control and motor).
ATTENTION!
In a residential environment, this product can cause high-frequency
disruptions that may require interference suppression measures.
9.2 Classification acc. to IEC/EN 61800-3
The generic standard defines test procedures and severity levels for every
environment of the drive control category; these have to be complied with.
Definition of the 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.
