1.1 Standards
In addition to the standards in accordance with EN 60079 / VDE 165-1,
separate standards for the corresponding types of protection apply to the
protection of motors in potentially explosive atmospheres.
Motors with type of protection for potentially explosive areas,
“increased safety”
The standard EN 60079-7 requires additional measures in the case of motors
with the type of protection for potentially explosive areas, “increased
safety”.
These measures ensure, with a high degree of certainty, that impermissible
high temperatures, sparks and electric arcs are prevented on motors where
these would not usually occur during normal operation.
The motor protection devices for this, which themselves are not located in a
potentially explosive area, must be certified by an accredited admission
office.
Motors in potentially explosive dust-air mixtures
For motors in potentially explosive dust-air mixtures, the standard
EN 60079-14 specifies additional measures.
Directive 2014/34/EC (ATEX) 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 20.04.2016.
