1.1 Foreword
In addition
to
the regulations in
accordance
with
EN 60079-14
and
VDE 0165-1,
separate regulations for the corresponding types of protection apply to the
protection of motors in potentially explosive atmospheres.
The standard EN 60079-7 requires additional measures for motors with igni-
tion protection type “e” “Increased Safety”. These measures improve the
degree of safety and prevent impermissible high temperature and develop-
ment of sparking and arcing, which is usually
not found
when
motors are
operated
under normal conditions.
The motor-protective devices for this that
are themselves not located in the Ex area must be certified by an accredited
certification body.
For for motors in potentially explosive dust-air mixtures, standard norm
EN 60079-14 specifies additional measures. Directive 94/9/EC (ATEX 100a)
on the approximation of the laws of the Member States concerning devices
and protective systems intended for use in potentially explosive areas has
been in force since 06.30.2003.
