Information
Potential damage
Devices in series SK 1x0E and the permitted options are only designed for a degree of mechanical stress that
corresponds to a low impact energy of 7J.
Higher loads will lead to damage to or in the device.
The necessary components for making adaptations are contained in the ATEX kits.

2.5.1.2 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. Option 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 parametrisation 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 no explosive dust atmosphere exists.
