9.2.2 Special conditions for safe use (ATEX Certificate TÜV 07
ATEX 554086 X)
1. For use as Gc- or Dc-apparatus (in zone 2 or 22) the field bus 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.
2. If the interface circuits are operated without the field bus 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.
3. DIP-switches, binary-switches and potentiometers, connected to the module
may only be actuated when explosive atmosphere can be excluded.
4. 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. This is
although and in particular valid for the interfaces "CF-Card", "USB",
"Fieldbus connection", "Configuration and programming interface",
"antenna socket", "D-Sub" and the "Ethernet interface". These interfaces
are not energy limited or intrinsically safe circuits. 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 and
750-633 the following shall be considered: The interface circuits shall be
limited to overvoltage category I/II/III (non mains/mains circuits) as defined
in EN 60664-1.
6. For the type 750-601 the following shall be considered: Do not remove or
replace the fuse when the apparatus is energized.
7. The ambient temperature range is: 0°C ≤ T
please note certificate).
