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.

Installation
a) The installation must 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) This apparatus is an associated electrical apparatus and is normally mounted in a non-
hazardous [safe] area. Specific apparatus described as Category 3 compliant may be
installed in a Zone 2 location providing that the relevant installation conditions are met. 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.
c) 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.
Read also the Special Conditions for Safe Use (below) for any additional or more specific
information.
Special Conditions of Safe Use for Zone 2 applications
a) When used in Zone 2, the equipment must be installed in an enclosure or an

the relevant material and environmental requirements of EN 60079-0:2012
and EN 60079-15:2010.
b) The equipment must not be inserted or removed unless either:
i) the area in which the equipment is installed is known to be non-hazardous
or
ii) the circuit to which it is connected has been de-energised.
c) The 24V supply for this equipment must be derived from a regulated power
supply complying with the requirements of European Community Directives.
d) For 5511, 5514, 5514D, 5516C, 5517, 5526 & 5532 only: Relay contacts may
