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.
c) This equipment has been designed to meet the requirements of intrinsically safe electrical
apparatus in accordance with EN 60079-0, EN 60079-11 and EN 60079-26.
Installation
a) reference to the IEC code of practice IEC 60079-14. In addition, particular industries or end

Group II gases, and each module shall be provided with an enclosure that is commensurate
with the environment into which it is installed.
3. The supply to the modules must be derived from a suitably certified, intrinsically safe supply.
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.
