10. Approvals, standards and
guidelines
This chapter contains information about electromagnetic
compatibility (EMC), and applicable guidelines, norms and
standards.
For binding information about the relevant drive controller
approvals, please refer to the relevant type plate!

10.1 EMC limit classes

Please note that EMC limit classes are only reached if the
standard switching 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 mounting on a wall, the
shielded motor cable must not exceed a maximum length
of 3 m!
Wiring suitable for EMC also requires that EMC screw
connections be used on both sides (drive controller and
motor).
IMPORTANT INFORMATION
In a residential environment, this product can cause
high-frequency disturbances that may require
interference suppression measures.
10.2 Classification acc. to
IEC/EN 61800-3
The generic standard defines test procedures and severity
levels for every environment in the drive controller
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 environments with their own supply network that
is separated from the public low-voltage supply by a
transformer.

10.3 Harmonics currents and grid
impedance for devices > 16 A and
≤ 75 A
Extract from EN 61000-3-12, applies to devices with a
rated current > 16 A and ≤ 75 A, which are intended for
connection to public low-voltage grids.
This device complies with IEC 61000-3-12 provided that
the short-circuit power S
SC
customer's system connects with the public grid is
greater than or equal to R
SCE
If found to be necessary after contacting the distributor
grid operator, the installer or operator of the device is
responsible for ensuring that the device is only
connected at a point with a short-circuit power S
greater than or equal to R
SCE
Grid's short-circuit power at point where
R

customer's system connects with the public grid.
