Danger
When using the WAGO-I/O SYSTEM 750 (electrical operation) with Ex ap-
proval, the following points are mandatory:
The fieldbus independent I/O System Modules Type 750-xxx are to be instal-
led in enclosures that provide for the degree of ingress protection of at le-
ast IP54.
For use in the presence of combustible dust, the above mentioned modules
are to be installed in enclosures that provide for the degree of ingress pro-
tection of at least IP64.
The fieldbus independent I/O system may only be installed in hazardous areas
(Europe: Group II, Zone 2 or America: Class I, Division 2, Group A, B, C,
D) or in non-hazardous areas!
Installation, connection, addition, removal or replacement of modules, field-
bus connectors or fuses may only take place when the system supply and
the field supply are switched off, or when the area is known to be
non-hazardous.
Ensure that only approved modules of the electrical operating type will be
used. The Substitution or Replacement of modules can jeopardize the sui-
tability of the system in hazardous environments!
Operation of intrinsically safe EEx i modules with direct connection to sen-
sors/actuators in hazardous areas of Zone 0 + 1 and Division 1 type requi-
res the use of a 24 V DC Power Supply EEx i module!
DIP switches and potentiometers are only to be adjusted when the area is
know to be non-hazardous.
Further Information
Proof of certification is available on request. Also take note of the informa-
tion given on the module technical information sheet.
