For use as Gc- or Dc-apparatus (in zone 2 or 22) the Field bus IndependentI/O Modules WAGO-I/O-SYSTEM 750-*** shall be erected in anenclosure that fulfils the requirements of the applicable standards (see themarking) EN 60079-0, EN 60079-11, EN 60079-15 and EN 60079-31.For use as group I electrical apparatus M2 the apparatus shall be erected inan enclosure that ensures a sufficient protection according to EN 60079-0and EN 60079-1 and the degree of protection IP64.The compliance of these requirements and the correct installation into anenclosure or a control cabinet of the devices shall be certified by an ExNB.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 the interfaces “Memory-Card”,“USB”, “Fieldbus connection”, “Configuration and programming interface”,“antenna socket”, “D-Sub”, “DVI-port” and the “Ethernet interface”. Theseinterfaces are not energy limited or intrinsically safe circuits. An operatingof 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 and750-633 the following shall be considered: The Interface circuits shall belimited to overvoltage category I/II/III (non mains/mains circuits) as definedin EN 60664-1.6. For replaceable fuses the following shall be considered: Do not remove orreplace the fuse when the apparatus is energized.7. The following warnings shall be placed nearby the unit:WARNING – DO NOT REMOVE OR REPLACE FUSE WHENENERGIZEDWARNING – DO NOT SEPARATE WHEN ENERGIZEDWARNING – SEPARATE ONLY IN A NON-HAZARDOUS AREAPos : 78.17 /D okumentati on allgemei n/Gli ederungsel emente/---Seitenwec hs el--- @ 3\mod_1221108045078_0.doc x @ 21810 @ @ 1
