ATEX information
The Essential Health and Safety Requirements (Annex II) of the EU Directive 2014/34/
EU [the ATEX Directive - safety of apparatus] requires that the installation manual of
all equipment used in hazardous areas shall contain certain information. This annex
is included to ensure that this requirement is met. It complements the information
presented in this document and does not conflict with that information. It is only
relevant to those locations where the ATEX directives are applicable.
7 .1
General
a) In common with all other electrical apparatus installed in hazardous areas, this
apparatus 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) The apparatus has been designed and manufactured so as 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.
c) This apparatus has been designed to meet the requirements of electrical
apparatus in accordance with EN 60079-0, EN 60079-1, EN 60079-7,
EN 60079-11, EN 60079-18 and EN 60079-31.
7 .2
Installation
a)The installation should comply with the appropriate European,
national and local regulations, which may include 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) The enclosures are certified:
II 2(1) GD
Ex d e ib mb [ia Ga] IIC T4 Gb
Ex tb IIIC T80°C Db
(–40°C
≤
Ta
≤
+70°C)
and are designed for installation in Zone 1 and Zone 2 hazardous areas.
c) The apparatus must not be subjected to mechanical and thermal stresses in
excess of those permitted in the certification documentation, this manual and
the product specification.
d) All cables and their glands must be chosen to withstand the temperatures at
which the apparatus is designed to operate. See product specification for
details.
e) The apparatus must not be installed in a position where it may be attacked by
aggressive substances.
g) All empty enclosure holes must be fitted with:
1. ≥IP66 Ex eb tb Equipment certified blanking plugs or ≥IP66 Ex eb tb
Equipment certified cable glands. All blanking plugs and glands must have a
minimum temperature range (-40°C to +75°C).
2. ≥IP66 Ex eb tb breather IECEx & ATEX equipment certified with a
minimum temperature range of -40°C to +75°C and IP rating (IP66) at least
equal to that of the enclosure.
