For use as Dc- or Gc-apparatus (in zone 2 or 22) the fieldbus independentI/O modules WAGO-I/O-SYSTEM 750-*** shall be erected in an enclosurethat fulfils the requirements of the applicable standards (see the marking)IEC 60079-0, IEC 60079-11, IEC 60079-15, IEC 61241-0 and IEC 61241-1.For use as group I, electrical apparatus M2, the apparatus shall be erected inan enclosure that ensures a sufficient protection according to IEC 60079-0and IEC 60079-1 and the degree of protection IP64. The compliance ofthese requirements and the correct installation into an enclosure or a controlcabinet of the devices shall be certified by an ExCB.2. Measures have to be taken outside of the device that the rating voltage is notbeing exceeded of more than 40% because of transient disturbances.3. DIP-switches, binary-switches and potentiometers, connected to the modulemay only be actuated when explosive atmosphere can be excluded.4. The connecting and disconnecting of the non-intrinsically safe circuits isonly permitted during installation, for maintenance or for repair purposes.The temporal coincidence of explosion hazardous atmosphere andinstallation, maintenance resp. repair purposes shall be excluded.This is although and in particular valid for 758-87x for the interface X1“CF-Card” and the interface X10, X11 “USB” and the Ethernet interfacesX8 and X9. These interfaces are not energy limited or intrinsically safecircuits. An operating of those circuits is in the behalf of the operator.5. For the types 750-606, 750-625/000-001, 750-487/003-000, 750-484 thefollowing shall be considered: The interface circuits shall be limited toovervoltage category I/II/III (non mains/mains circuits) as defined in IEC60664-1.6. For the type 750-601 the following shall be considered: Do not remove orreplace the fuse when the apparatus is energized.7. The ambient temperature range is: 0°C ≤ Ta ≤ +55°C (for extended detailsplease note certificate).Pos: 56.28 /Dokumentation allgemein/Gliederungselemente/---Seitenwechsel--- @ 3\mod_1221108045078_0.doc @ 21810 @ @ 1
