2.6 Information on explosion protection
WARNING
Machines that are designed without explosion protection must not be used
in workshops that come under the explosion protection ordinance.
Explosion-protected devices are labelled as such by means of an
EC declaration of conformity in accordance with ATEX 94 /9 /EC and
the Ex marking on the type plate.
Explosion-protected machines meet the explosion protection requirements
of Directive 94/9/EC for the explosion group, unit category and temperature
classspeciedonthetypeplateorinthedeclarationofconformity.
The operator is responsible for determining the zone allocation according
to the Directive of EC 94/9/EC, Appendix II, no. 2.1-2.3 when observing the
measures of the responsible inspecting authority. The operator is responsible
for checking and ensuring that all technical data and markings according to
ATEX correspond with the necessary requirements.
Please note that several components have their own type plate with separate
marking according to ATEX. In this case the lowest explosion protection of
all attached markings applies for the entire machine. Applications where the
malfunction of the unit can lead to danger to personnel must be provided
with respective safety measures by the operator.
However, if agitators, heaters or other electrically accessories are
additionally mounted, one must check the explosion protection. Plugs for
heaters, agitators, etc. that do not have explosion protection, may only
be plugged in outside of areas that fall under the explosion protection
ordinance, even if the accessory equipment as such is explosion protected.
