Before final installation, the operator needs to decide on the
use of the device, either
A) as a device with 'Ex i' intrinsically safe type of protection
or
B) as a device with 'Ex d' type of protection
and permanently mark the selected type of use on the name
plate. Specific conditions of the surrounding environment,
such as chemical corrosion, must be taken into account when
affixing the permanent mark. Only the manufacturer must
change the selected type of use following a re-examination
Variants that, according to declarations, also meet the
requirements for the 'flameproof enclosure' type of
protection may no longer be used as 'intrinsically safe' if they
have been previously used as a flameproof type of protection
