5 APPENDIX A - 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
5 .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) This apparatus also meets the requirements of protection ‘n’ in accordance with IEC/EN 60079-15.
5 .1 .1
9121-IS and 9122-IS only
a) This apparatus has been designed to meet the requirements of associated electrical apparatus in
accordance with IEC/EN 60079-0 and IEC/EN 60079-11.
b) This apparatus also meets the requirements of protection ‘n’ in accordance with IEC/EN 60079-15.
5 .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 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. If necessary the product
must be protected by an enclosure to prevent mechanical damage.
c) The apparatus must not be installed in a position where it may be attacked by aggressive substances
and must be protected from excessive dust, moisture and other contaniments by an enclosure.
5 .2 .1
9121-IS and 9122-IS only
a) This apparatus is an associated electrical apparatus and is normally mounted in a non-hazardous
[safe] area. It meets the requirements of Category 3 apparatus and 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.
WARNING !
If the equipment is mounted in Zone 2, the Host Power and Terminator switches
shall only be operated if the equipment is de-energised or the area is known to be
gas free.
5 .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.
b) Access to the internal circuitry must not be made during operation.
c) If the outer enclosure of the apparatus needs to be cleaned, this should be done with a cloth lightly
moistened by a dilute mixture of detergent in water.
5 .4 Repair
a) The products cannot be repaired by the user and must be replaced with an equivalent certified
product. Repairs should only be carried out by the manufacturer or his authorised agent.
