Commissioning (installation and configuration) Nivotester FTL325P
18 Endress+Hauser
3.4 Basic conditions for use in safety-related applications
The measuring system must be used correctly for the specific application, taking into account
the medium properties and ambient conditions. Carefully follow instructions pertaining to
critical process situations and installation conditions from the Operating Instructions. The
application-specific limits must be observed. The specifications in the Operating Instructions
and the Technical Information must not be exceeded.
3.4.1 EMC compatibility
The Nivotester is certified in accordance with IEC 61326-3-2 and is thus suitable for safety-
related, industrial applications in a specified electromagnetic environment. If the specified
electromagnetic ambient conditions are exceeded, the switch status might not be reliably
detected. An unshielded cable up to 1 000 m (3 281 ft) long can be used between the devices
in these environmental conditions. Electromagnetic interference immunity can be further
improved by using shielded cables.
3.5 Useful lifetime of electric components
The established failure rates of electrical components apply within the useful lifetime as per
IEC 61508-2:2010 section 7.4.9.5 note 3.
According to DIN EN 61508-2:2011 section 7.4.9.5 (national footnote N3) appropriate
