Safety notices
When used in hazardous environments corresponding to Class I, Division 2 or Class I,
Zone 2, the device must be installed in a cabinet or a suitable enclosure.
To comply with EC 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 device is operated at an ambient
temperature of 0 °C - 60 °C, make sure that you use cables with a permitted ambient
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).
Do not use any parts that show evidence of damage.
DO NOT CONNECT OR DISCONNECT EQUIPMENT WHEN A FLAMMABLE OR
COMBUSTIBLE ATMOSPHERE IS PRESENT.
