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
provide a higher degree of safety and prevent impermissible high
temperature and development of sparking and arcing on the motors, which
usually does not occur under normal operating 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 60079-14 specifies
additional measures.
The guidelines on the application of Directive 94/9/EC (ATEX 95) resp.
2014/34/EU 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 ZB65-.../XTOB...DC1 and ZB150-.../XTOB...GC1 overload relays are
certified according to the 94/9/EC (ATEX 95) resp. 2014/34/EU Directives.
