Installation in connection with intrinsically safe circuits

Installation of the intrinsically safe power circuits of the devices is permitted in potentially
explosive zones, whereby, in particular, safe separation from all non-intrinsically safe power
circuits must be guaranteed.
The intrinsically safe current circuits must be installed according to valid setup regulations.
For the interconnection of the intrinsically safe field devices and the intrinsically safe power
circuits of the associated devices, the respective maximum values of the field device and the
associated device with regard to explosion protection must be observed (proof of intrinsic
safety). EN 60079-14/IEC 60079-14 must be observed.
