2.3 Usage in explosive atmospheres
When used in explosive atmospheres, the standard measuring system has to be
installed in an appropriate explosion protective enclosure and subject to requirements.
The products are labeled with an additional
marking on the nameplate:

The “intended use” as well as any information on the safe usage of the ATEX-
compliant measuring system in explosive atmospheres are contained in the
User
Manual.
Standard measuring systems that are installed in the explosion protection enclosure
can therefore be used in explosive atmospheres.
When the measuring system is installed in the explosion protection enclosure, which
means that it meets explosion protection requirements, the properties of the
measuring system will no longer be as they were originally.
Following the specifications in the
User Manual, please check whether the
properties defined in that manual meet the application-specific requirements.
Fail-safe usage requires additional measures and requirements. Such measures and
requirements must be determined prior to initial commissioning and must be taken and
met accordingly.
