Electromagnetic compatibility (EMC)
All electrical equipment that have an intrinsic, independent function and are placed on the market as individual
units for users must comply from January 1996 with the EEC directive EEC/89/336 . There are three different
ways for manufacturers to display compliance with this directive:
1.
EC conformance declaration
This is a declaration by the manufacturer that the requirements in the applicable European standards for
the electrical environment of the equipment are met. Only those standards that are published in the
Official Journal of the European Community can be cited in the manufacturer declaration.
2.
Technical documentation
Technical documentation can be produced that describes the EMC behaviour of the equipment. 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 approval test certificate
This method only applies to radio transmitter equipment.
NORDAC servo controllers only have a function when they are connected to other equipment (e.g. with a motor).
The base units cannot therefore carry the CE mark that 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 1: 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 2: Interference suppressed for industrial environments (operation has own supply
transformer)
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 50081-2 and EN 50082-2 for radiation and interference resistance in
industrial environments.
Class 3: Interference suppressed for domestic, commercial and light industry environments
In this operating class, the manufacturer can certify that his equipment meets the requirements of the EMC
directive for domestic, commercial and light industry environments with respect to their EMC behaviour in power
drives. The limit values correspond to the basic standards EN 50081-1 and EN 50082-1 for radiation and
interference resistance.
Note:
The NORDAC servo controllers are designed
solely for commercial applications
. They do not therefore
meet the requirements of the standard EN 61000-3-2 for radiation of harmonics.
