1.6.1 CE Conformity and Labeling
What is CE Conformity and Labeling?
The purpose of CE labeling is to avoid technical trade
obstacles within EFTA and the EU. The EU has introduced
the CE label as a simple way of showing whether a
product complies with the relevant EU directives and
standards. The CE label says nothing about the speci-
cations or quality of the product.
1.6.2 CE Mark
Illustration 1.1 CE
The CE mark (Communauté Européenne) indicates that the
product manufacturer conforms to all applicable EU
directives. The EU directives applicable to the design and
manufacture of frequency converters are listed in Table 1.3.
