homepage.
Electromagnetic compatibility
Instrumentsinfour-wireorExdiaversionaredesignedforuseinan
industrial environment. Nevertheless, electromagnetic interference
from electrical conductors and radiated emissions must be taken into
account, as is usual with class A instruments according to EN 61326-
1.Iftheinstrumentisusedinadierentenvironment,theelectromag-
netic compatibility to other instruments must be ensured by suitable
measures.
1.6 SIL qualication according to IEC 61508
The Safety Integrity Level (SIL) of an electronic system is used to as-
sess the reliability of integrated safety functions.
Fordetailedspecicationofthesafetyrequirements,multipleSIL
levelsarespeciedaccordingtosafetystandardIEC61508.Youcan
nddetailedinformationinchapter"Functional safety (SIL)" of the
operating instructions.
TheinstrumentmeetsthespecicationsofIEC61508:2010(Edi-
tion2).Itisqualiedforsingle-channeloperationuptoSIL2.The
instrument can be used homogeneously redundant up to SIL3 in
multi-channel architecture with HFT 1.
1.7 NAMUR recommendations
NAMUR is the automation technology user association in the process
industry in Germany. The published NAMUR recommendations are
acceptedasthestandardineldinstrumentation.
ThedevicefullstherequirementsofthefollowingNAMURrecom-
mendations:
• NE 21 – Electromagnetic compatibility of equipment
