8.2.1 Special Conditions for Safe Operation of the ATEX and IEC
Ex (acc. DEMKO 08 ATEX 142851X and IECEx PTB 07.0064)
The fieldbus-independent I/O modules of the WAGO-I/O-SYSTEM 750-.../...-...
must be installed in an environment with degree of pollution 2 or better. In the
final application, the I/O modules must be mounted in an enclosure with IP 54
degree of protection at a minimum with the following exceptions:
- I/O modules 750-440, 750-609 and 750-611 must be installed in an IP 64
minimum enclosure.
- I/O module 750-540 must be installed in an IP 64 minimum enclosure for
230 V AC applications.
- I/O module 750-440 may be used up to max. 120 V AC.
When used in the presence of combustible dust, all devices and the enclosure shall
be fully tested and assessed in compliance with the requirements of IEC 61241-
0:2004 and IEC 61241-1:2004.
When used in mining applications the equipment shall be installed in a suitable
enclosure according to EN 60079-0:2006 and EN 60079-1:2007.
I/O modules fieldbus plugs or fuses may only be installed, added, removed or
replaced when the system and field supply is switched off or the area exhibits no
explosive atmosphere.
DIP switches, coding switches and potentiometers that are connected to the I/O
module may only be operated if an explosive atmosphere can be ruled out.
I/O module 750-642 may only be used in conjunction with antenna 758-910 with
a max. cable length of 2.5 m.
To exceed the rated voltage no more than 40%, the supply connections must have
transient protection.
The permissible ambient temperature range is 0 °C to +55 °C.
