EMC GUIDE
To help you deal with installa
tion-dependent electromagnetic interference effects,Eurotherm
provides an ‘Electromagnetic compatibility’ installation guide (ref. HA 025464 ENG) which
sets out best current practice regarding EMC.
CE CONFORMITY DECLARATION is available on request.

EUROPEAN DIRECTIVES AND APPLICABLE STANDARDS
COMPLIANCE WITH PRODUCT STANDARD
7200A products comply with the terms of product standard EN 60947-4-3
‘Contactors and motor-starters - AC semiconductor controllers and contactors for non-motor loads’.
CE LABELLING
7200A products installed and used in accordance with the user manual, bear CE labelling on
the basis of compliance with the essential requirements of the European Low Voltage
Directive 73/23 EEC dated 19 February 1973, modified by 93/68/EEC dated 22 July 1993 and
the
Electromagnetic Compatibility Directive 89/336/EEC dated 3 May 1989 modified by
92/31/EEC dated 28 April 1992 and 93/68/EEC dated 22 July 1993.
SAFETY
The units have IP20 protection rating as defined by standard IEC 60529.
External wiring must comply with standards IEC 60364-4-43 and IEC 60943.
Copper cables and conductors must be used, rated to a temperature of 75°C (167°F).
ELECTROMAGNETIC COMPATIBILITY (EMC)
7200A products installed and used in accordance with the user manual, are designed for an
industrial environment and must not be used in the home.
IMMUNITY
The EMC immunity test standards required by the standard
EN 60947-4-3
