9.3 Electromagnetic compatibility
All electrical equipment that have an intrinsic, independent function and are placed on the market as
individual units for users from January 1996 must comply with the EU directive EU/89/336. There are three
different ways for manufacturers to display compliance with this directive:
1. EC declaration of conformity
This is a declaration from the manufacturer, stating that the requirements in the applicable European standards for
the electrical environment of the equipment have been met. Only those standards which are published in the Official
Journal of the European Community may be cited in the manufacturer’s declaration.
2. Technical documentation
Technical documentation can be produced which describes the EMC characteristics of the device. This
documentation must be authorised by one of the “Responsible bodies” named by the responsible European
government. This makes it possible to use standards that are still under preparation.
3. EC type test certificate (This method only applies to radio transmitter equipment.)
SK 205E/215E/225E/235E frequency inverters only have an intrinsic function when they are connected to other
equipment (e.g. with a motor). The basic units cannot therefore carry the CE mark, which would confirm compliance
with the EMC Directive. Precise details are therefore given below about the EMC behaviour of this product, based
on the proviso that it is installed according to the guidelines and instructions described in this documentation.
Class A, Group 2: General, for industrial environments
Complies with the EMC standard for power drives EN 61800-3, for use in secondary environments (industrial)
and when not generally available .
Class A, Group 1: Interference suppressed, for industrial environments
In this operating class, the manufacturer can certify that his equipment meets the requirements of the EMC directive
for industrial environments with respect to their EMC behaviour in power drives. The limit values correspond to the
basic standards EN 61000-6-2 and EN 61000-6-4 for interference immunity and interference emissions in industrial
environments.
Class B, Group 1: Interference suppressed for domestic, commercial and light industrial
environments
In this operating class, the manufacturer can certify that his equipment meets the requirements of the EMC directive
for domestic, commercial and light industrial environments with respect to their EMC behaviour in power drives. The
limit values correspond to the basic standards EN 61000-6-2 and EN 61000-6-4 for interference immunity and
interference emissions.
ATTENTION
NORDAC SK 2xxE frequency inverters are only intended for commercial applications .
They are therefore not subject to the requirements of the standard EN 61000-3-2 for radiation
of harmonics.
This device produces high frequency interference, which may make additional suppression
measures necessary in
domestic environments .
