2.3.2 Special conditions for safe use (ATEX Certificate TÜV 07 ATEX

554086 X)

For use as Gc- or Dc-apparatus (in zone 2 or 22) the fieldbus independent

I/O modules WAGO-I/O-SYSTEM 750-*** shall be erected in an enclosure

that fulfils the requirements of the applicable standards (see the marking) EN

60079-0, EN 60079-11, EN 60079-15, EN 61241-0 and EN 61241-1.

For use as group I, electrical apparatus M2, the apparatus shall be erected in an

enclosure that ensures a sufficient protection according to EN 60079-0 and EN

60079-1 and the degree of protection IP64. The compliance of these

requirements and the correct installation into an enclosure or a control cabinet

of the devices shall be certified by an ExNB.

If the interface circuits are operated without the fieldbus coupler station type

750-3../...-... (DEMKO 08 ATEX 142851 X) measures must be taken outside

of the device so that the rating voltage is not being exceeded of more than 40%

because of transient disturbances.

DIP-switches, binary-switches and potentiometers, connected to the module

may only be actuated when explosive atmosphere can be excluded.

The connecting and disconnecting of the non-intrinsically safe circuits is only

permitted during installation, for maintenance or for repair purposes.

The temporal coincidence of explosion hazardous atmosphere and installation,

maintenance resp. repair purposes shall be excluded.

For types 750-606, 750-625/000-001, 750-487/003-000, 750-484, the following

must be taken into account: The interface circuits must be limited to

overvoltage category I/II/III (electrical circuits without power supply/electrical

circuits with power supply) as defined in EN 60664-1.

For the type 750-601 the following shall be considered: Do not remove or

replace the fuse when the apparatus is energized.

The ambient temperature range is: 0°C ≤ Ta ≤ +55°C (for extended details

please note certificate).
