2.2 EMC directive
2.2.1 Introduction
The EMC Directive provides that the electrical apparatus must not excessively disturb the
environment it is used in, and, on the other hand, it shall have an adequate level of immunity toward
other disturbances from the same environment.
The compliance of VACON
®
NX Active Front End with the EMC Directive is verified with Technical
Construction Files (TCF) and checked and approved by SGS FIMKO, which is a Notified Body. The
Technical Construction Files are used to authenticate the conformity of VACON
®
NX Active Front End
with the Directive because it is impossible to test such a large product family in a laboratory
environment and because the combinations of installation vary greatly.
