The opening of European markets implies a harmonization of regulations in the
various European Union member states.
European Directives are documents used to remove obstacles to the free movement
of goods and their application is compulsory in all states of the European Union.
Member states are obliged to transcribe each Directive into their national legislation
and, at the same time, to withdraw any conflicting regulations.
The Directives, particularly those of a technical nature with which we are concerned,
only set objectives, called “general requirements”.
The manufacturer must take all necessary measures to ensure that his products
conform to the requirements of each Directive relating to his equipment.
As a general rule, the manufacturer affirms that his product conforms to the
necessary requirements of the Directive(s) by applying the
e label to his product.
e marking is applied to Telemecanique products where relevant.
p e marking on a product means that the manufacturer certifies that his product
conforms to the relevant European Directives ; it is necessary in order that a product
which is subject to a Directive(s) can be marketed and freely moved within the
European Union.
p e marking is intended solely for the national authorities responsible for market
regulation.
For electrical equipment, only conformity of the product to standards indicates that it
is suitable for use, and only a guarantee by a recognised manufacturer can ensure
a high level of quality.
One or more Directives, as appropriate, may apply to our products, in particular :
p The Low Voltage Directive 72/23/EEC amended by Directive 93/68/EEC : e
marking under the terms of this Directive could not be applied before 1 January 1995
and is compulsory as of 1 January 1997.
p The Electromagnetic Compatibility Directive 89/336/EEC, amended by Directives
92/31/EEC and 93/68/EEC :
e marking on the products covered by this Directive
has been compulsory since 1 January 1996.
Advantys, STB distributed I/O meet the requirements of “TC” treatment (1).
For installations in industrial production workshops or in an environment which
corresponds to “TH” treatment (2), STB distributed I/O should be enclosed in casings
with a minimum of IP 54 protection as prescribed by standards IEC.
Advantys, STB distributed I/O are supplied with an IP 20 protection index. They can
therefore be installed without enclosure in locations with restricted access which do
not exceed pollution degree 2 (control room which does not contain a machine or
dust-producing activity).
(1) “TC” treatment : all climate treatment.
(2) “TH” treatment : treatment for hot and humid environments.
