1.1 Foreword

1.2 Notes and Standards

In addition to the regulations in accordance with EN 60079-14 and VDE 0165
Part 1, separate regulations for the corresponding degrees of protection
apply to the protection of motors in potentially explosive atmospheres. The
standard EN 60079-7 requires additional measures for motors with ignition
protection type "e", "Increased Safety". These measures provide an
increased level of safety and thus prevent the possibility of impermissibly
high temperatures and the occurrence of sparks and arcing in motors in
which this does not occur in normal operation. The motor-protective devices
for this that are themselves not located in the Ex area must be certified by an
accredited certification body.
For motors in potentially explosive dust-air mixtures, standard norm
EN 60079-14 specifies additional measures.
Directive 94/9/EG resp. 2014/34/EU on the approximation of the laws of the
Member States concerning devices and protective systems intended for use
in potentially explosive areas.
Due to the heightened risk in potentially explosive areas, the following notes
and standards have to be observed carefully:
• EN 60079-14 / VDE 0165-1:
Electrical apparatus for explosive gas atmospheres.
• EN 60079-17:
Inspection and maintenance of electrical installations in hazardous areas.
• EN 50495:
Safety devices required for the safe functioning of equipment with
respect to explosion risks.
