Safety Manual SIL KCD2-STC-(Ex)1.HC(.SP), HiC2025HC
Safety Recommendation
Our experience has shown that the useful life time of a Pepperl+Fuchs product
can be higher
if there are no components with reduced life time in the safety path (like

electrolytic capacitors, relays, flash memory, opto coupler) which can produce
dangerous undetected failures and
if the ambient temperature is significantly below 60 °C.

Please note that the useful life time refers to the (constant) failure rate of the
device. The effective life time can be higher.

Installation and Commissioning

installation or replacement of the device the loop has to shut down. Devices have
