Below you will find important information on the installation of the ET 200S distributed I/O
system in a hazardous area.
Note
Subassemblies/modules with ATEX
II 3 G Ex nA II T3 .. T6 certification can only be used in
SIMATIC systems rated as category
3 equipment.
If repair is necessary, the affected module must be sent to the production location. Repairs
can only be carried out there.
Special conditions for the following are shown below:
● Subassemblies/modules must be installed in an adequate housing. This must comply with
the IP54 degree of protection (according to EN 60529) as a minimum. The environmental
conditions under which the equipment is installed must be taken into account. There must
be a manufacturer’s declaration for zone 2 available for the housing (in accordance with
EN 60079-15).
● If a temperature of > 70° C is reached in the cable or at the cable entry of this housing
under operating conditions, or if a temperature of > 80° C can be reached at the junction
of the conductors under operating conditions, the temperature-related properties of the
cables must correspond to the temperatures actually measured.
● The cable entries used must comply with the required IP degree of protection and the
information in the section on "Commissioning" (in accordance with EN 60079-15).
● Steps must be taken to ensure that the rated voltage through transients cannot be
exceeded by more than 40%.
