In addition to the degree of protection specified in the standards
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 60079-7 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 motors in explosive dust-air mixtures, standard EN 60079-14 specifies
additional measures.
The guidelines on the application of Directive 94/9/EG (ATEX 95) resp.
2014/34/EU (ATEX) 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 June 30, 2003.
The motor-protective PKZM0-.../XTPR...BC1NL, PKZM0-...-T/XTPT...BC1NL
system is approved according the 94/9/EG (ATEX 95) resp. 2014/34/EU
(ATEX) Directives.
