ATEX & IECEx CERTIFICATION INFORMATION
The following information is in accordance with the Essential Health and Safety Requirements
(Annex II) of the EU Directive 2014/34/EU [the ATEX Directive - safety of apparatus] and is
provided for those locations where the ATEX Directive is applicable.
General
a)
This equipment must only be installed, operated and maintained by competent
personnel. Such personnel shall have undergone training, which included instruction on
the various types of protection and installation practices, the relevant rules and
regulations, and on the general principles of area classification. Appropriate refresher
training shall be given on a regular basis. [See clause 4.2 of EN 60079-17].
b)
This equipment has been designed to provide protection against all the relevant
additional hazards referred to in Annex II of the directive, such as those in clause
1.2.7 . This equipment has been designed to meet the requirements of intrinsically safe
electrical apparatus in accordance with EN 60079-0, EN 60079-11, EN 60079-15 and
EN 60079-26.
Installation
a)
reference to the IEC code of practice IEC 60079-14. In addition, particular industries
or end users may have specific requirements relating to the safety of their installations
and these requirements should also be met. For the majority of installations the
Directive 1999/92/EC [the ATEX Directive - safety of installations] is also applicable.
b)
Unless already protected by design, this equipment must be protected by a suitable
enclosure against:
i) mechanical and thermal stresses in excess of those noted in the certification
documentation and the product specification.
ii) aggressive substances, excessive dust, moisture and other contaminants.
c)
This apparatus is intrinsically safe electrical apparatus and is normally mounted in
a safe area. When mounted in a Zone 2 location the apparatus must be provided
with an enclosure, which offers an additional degree of protection appropriate to the
area classification.
Special conditions for safe use (when mounted in a Zone 2 hazardous area)
a)
If the equipment is installed in a zone 2 hazardous area, it shall be housed in an
enclosure that is coded Ex nA, Ex e, Ex d or Ex p, suitable for operating temperatures
of -40°C to +135°C and providing an ingress protection of IP54 minimum. For some
types of enclosure, additional certification will be required to permit the installation of
the module within the enclosure. Reference should be made to the enclosure
certificate. The installer shall ensure that the maximum ambient temperature of the
module when installed is not exceeded.
b) When the device is mounted in a zoned area, connection and disconnection of the
modules input supply voltage while live is only permitted if the potentially explosive
atmosphere is shown to be absent.
Inspection and maintenance
a)
Inspection and maintenance should be carried out in accordance with European,
national and local regulations which may refer to the IEC standard IEC 60079-17 . In
addition specific industries or end users may have specific requirements which should
also be met.
b)
Access to the internal circuitry must not be made during operation.
Repair
This product cannot be repaired by the user and must be replaced with an equivalent
certified product.
