2 EMC - legal foundation
The legal foundation is the EMC Directive and its implementation by the respective EU member
states’ existing national law. In Germany, this is the German EMC Act, in force since 1996, and the
rules and regulations of its application.
The gist of its central requirement is that the operation of electrical and electronic equipment,
systems, or devices must not produce any impermissible mutual interferences.
Within the meaning of the requirements arising from the EMC Directive, there may be varying
interpretations at the time of product rating. The EMC behaviour of an electrical or electronic device
is essentially determined by
z its interference emissions
z its immunity to interference.
As far as the EMC characteristics of a product are concerned, the manufacturer and / or the party
introducing it to the market is always obliged to meet special requirements with respect to
information. In their documentation (Operating Instructions), Lenze specify conformity to standards
and provide detailed installation instructions.
2.1 EMC product standard for variable-speed electrical drives
EN 61800-3 defines limit values and test procedures for drives and
z covers the electrical drive system from the mains connection to the motor shaft end,
z takes into consideration
– various distribution channels,
– various environments (residential / industrial),
– external connections and internal interfaces.
It defines assessment criteria for the operational behaviour on interference at the external
connections and internal interfaces and includes requirements to be met by the immunity to
interference in accordance with the environment at the place of use.
2.2 Place of use
The place of use is divided into two so-called environments:
Environment 1
Residential, business, and industrial: Environment that contains residential areas and facilities that
are connected directly without adapter transformer to a low-voltage mains that supplies residential
buildings.
Environment 1
Industrial: Facilities that are not directly connected to a low-voltage mains supplying residential
areas.
