2.5 CE conformity
What is the purpose of the EC directives?
EC directives are issued by the European Council and are intended
for the determination of common technical requirements
(harmonization) and certification procedures within the European
Community. At the moment, there are 21 EC directives of product
ranges. The directives are or will be converted to national
standards of the member states. A certification issued by one
member state is valid automatically without any further approval in
all other member states.
The texts of the directive are restricted to the essential
requirements. Technical details are or will be determined by the
European harmonized standards.
What does the CE mark imply?
After a verification, the conformity to the EC directives is certified by
affixing a CE mark. Within the EC, there are no commercial barriers
for a product with the CE mark. The enclosure of a conformity
certification is not necessary according to most directives.
Therefore, the customer cannot clearly see which of the 21 EC
directives applies to a product and which harmonized standards are
considered in the conformity verification.
Drive controllers with the CE mark themselves correspond
exclusively to the Low-voltage Directive. For the compliance with
the EMC directive only general recommendations have been issued
so far. The CE conformity of the installed machine remains the
responsibility of the user. For the installation of CE-typical drive
systems, Lenze has already proved the CE conformity to the EMC
directive.
What is the purpose of the EMC directive?
The EC directive relating to electromagnetic compatibility is
effective for "equipment" which may either cause electromagnetic
disturbances or be affected by such disturbances.
The aim is the limitation of the generation of electromagnetic
disturbances so that the operation of radio and telecommunication
systems and other equipment is possible. Furthermore, the units
must be immune against electromagnetic disturbances to ensure an
application as directed.
What is the objective of the Low-Voltage Directive?
The Low-Volgate Directive is effective for all electrical equipment
for the use with a rated voltage between 50 V and 1000 V AC and
between 57 V and 1500 V DC under normal ambient conditions.
The use of electrical equipment in e.g. explosive atmospheres and
electrical parts in passenger and goods lifts are excepted.
The objective of the Low-voltage Directive is to ensure that only
such electrical equipment which does not endanger the safety of
man or animals is placed on the market. It should also be designed
to conserve material assets.
