Foreword In addition to the degree of protection specified in the stan-
dards EN 60079-14 and VDE 0165 Part 1, further provisions
have been made to ensure safety from ignition for motors
operated in potentially explosive atmospheres. EN 50019
prescribes additional measures to be taken for the operation
motors with “increased safety” type of protection “e”.
These measures improve the degree of safety and prevent
impermissible high temperature and development 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 e area must be certified by an accredited
certification body.
For for motors in explosive dust-air mixtures, standard
EN 61214 specifies additional measures.
The guidelines on the application of Directive 94/9/EC
(ATEX 100a) on the approximation of the laws of the
Member States concerning equipment and protective
systems intended for use in potentially explosive
atmospheres will be enforced as of 06.30.2003.
The motor-protective PKZM0/XTPR…BC1 system is
approved by the PTB according the 94/9/EC (ATEX 100a)
Directives.
