Notices on use in hazardous areas according to ATEX / IECEx

To comply with EC Directive 2014/34/EU (ATEX 114) or the conditions of IECEx, this
enclosure or cabinet must meet the requirements of at least IP54 in compliance with EN
60529.
If the cable or conduit entry point exceeds 70 °C or the branching point of conductors
exceeds 80 °C, special precautions must be taken. If the equipment is operated in an air
ambient in excess of 50 °C, only use cables with admitted maximum operating temperature
of at least 80 °C.
Take measures to prevent transient voltage surges of more than 40% of the rated voltage.
This is the case if you only operate devices with SELV (safety extra-low voltage).
