1.3.4 EC Directive on electromagnetic compatibility
(89/336/EWG)
amended by:
z First Amendment Directive (92/31/EWG)
z CE Mark Directive (93/68/EWG)
1.3.4.1 General
z The EC Directive ”Electromagnetic Compatibility” applies to ”devices” which may cause
electromagnetic interferences or the operation of which may be impaired by such
interferences.
z The aim is to limit the generation of electromagnetic interferences such that radio and
telecommunication systems and other equipment can be operated without interferences.
Furthermore the devices must show an appropriate resistance against electromagnetic
interference to ensure the application as directed.
z Controllers cannot be operated on their own. Controllers cannot be evaluated on their own in
terms of EMC. Only when being integrated into a drive system the compliance with the
objectives of the EC Directive ”EMC” and the observance of the ”Law on electromagnetic
compatibility of devices” can be checked.
z Lenze has evaluated the conformity of the controllers in defined drive systems. In the
following, these evaluated drive systems are called ”CE-typical drive system”. Therefore the
user of the controllers can
– either determine the system components and their integration into a drive system and
declare the conformity on his own responsibility,
– or install the drive system according to the CE-typical drive system evaluated by the inverter
manufacturer who already proved the conformity.
