Notices regarding use in hazardous areas according to ATEX
Requirements for the cabinet/enclosure
To comply with EU Directive 94/9 (ATEX95), this enclosure 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).
