Special Conditions For Safe Use (Atex Certificate Tüv 07 Atex 554086 X) - WAGO I/O-SYSTEM 750 Manual

3.2.2 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
