7.2.3
Special Conditions for Safe Use
(IEC-Ex Certificate TUN 14.0035X)
1.
The modules of the WAGO-I/O-SYSTEM 750-*** have to been erected in
such a way, that corresponding to IEC 60079-15 a degree of protection of at
least IP 54 according to IEC 60529 is achieved.
2.
Measures have to been taken, external to the modules, to provide a transient
protection that ensures that the rated voltage, connected to the power supply
terminals, is not exceeded by more than 40 %.
3.
The connecting and disconnecting of the non-intrinsically safe circuits is
only permitted if no explosive atmosphere exists. This although applies for
the all switches, interfaces (Fieldbus, Ethernet, Serial) and the SD-card.
