Options for ATEX zone 22, category 3D
In order to ensure that the device is ATEX-compliant, its optional modules must also be approved for
potentially explosive areas. Optional modules that are not in the following list may
not
be used in an
ATEX zone 22 3D. This also includes connectors and switches that may also not be used in such an
environment.
Control and parameterization units
are basically
not
approved for
operation in
ATEX - zone 22 3D
. They may therefore only be used for commissioning or maintenance purposes
and if it has been ensured that there is no explosive dust atmosphere.
