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.
6.1
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 in
accordance with EN 60079-0 and EN60079-11. The
MTL831B transmitter is certified ‘ia’ and is normally mounted in
a Zone 1 hazardous area. The MTL3052 meets the
requirements of Associated Apparatus for category ‘ia’ and is
always mounted in the safe area.
c)
This 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.

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 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 contaminants.
