Special conditions for ATEX, operation as intrinsically safe equipment
• Prior to final installation, the owner must decide how the device is to be used, either
A) as a device featuring the intrinsically safe "Ex i" type of ignition protection, or
B) as a device with the "Ex d" type of ignition protection,
and he/she must mark the selected type of use on the name plate in a permanent manner.
Specific ambient conditions such as chemical corrosion should be taken into account when
affixing the permanent mark. Only the manufacturer may change the selected type of use
following a review.
• Variants with special certification confirming that they meet the requirements for the
"flameproof enclosure" type of ignition protection may not be used as "intrinsically safe", if
they have been previously used as a flameproof type of ignition protection.
