8.3.2 EMC evaluation
Two standards must be observed when evaluating electromagnetic compatibility.
1. EN 55011-1 (environmental standard)
The limits are defined in dependence on the basic environment in which the product is operated in
this standard. A distinction is made between 2 environments, whereby the 1st environment
describes the non-industrial living and business area without its own high-voltage or medium-
voltage distribution transformers. The 2nd environment, on the other hand, defines industrial
areas which are not connected to the public low-voltage network, but have their own high-voltage
or medium-voltage distribution transformers. The limits are subdivided into classes A1, A2 and B.
2. EN 61800-3 (product standard)
The limits are defined in dependence on the usage area of the product in this standard. The limits
are subdivided into categories C1, C2, C3 and C4, whereby class C4 basically only applies to
drive systems with higher voltage (≥ 1000 V AC), or higher currents (≥ 400 A). However, class C4
can also apply to the individual device if it is incorporated in complex systems.
The same limits apply to both standards: However, the standards differ with regard to an application
that is extended in the product standard. The user decides which of the two standards applies,
whereby the environmental standard applies in the event of a typical fault remedy.
The main connection between the two standards is explained as follows:
