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 compliments 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.
8.1
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.
8.2
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 ≤ T a ≤ +70°C) and
are designed for installation in Zone 1 or 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.
Read also the Special Conditions for Safe Use (below) for any additional or more
specific information.
Special Conditions for Safe Use
1. The equipment shall only be powered from supplies conforming to IEC 61158
2. When a Trunk Surge Module is fitted, due to the presence of transient
protection components the power input circuit will not withstand a 500V a.c.
isolation test to earth without breakdown occurring.
3. When one or more Spur Surge Modules are fitted, due to the presence of
transient protection components the spur outputs will not withstand a 500V
a.c. isolation test to earth without breakdown occurring.
8.3
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.
