Note
The standard version includes explosion protection for gases and dust.
• If the installation location for the device is classified as a potentially explosive area for gases and dust, the temperature data
in the "Gas & dust" columns in the table must be taken into consideration.
• If the installation location for the device is classified as a potentially explosive area for gases only, the temperature data in
the "Gas" columns in the table must be taken into consideration.
