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.
