The SIL O2 oxygen analyzer is an associated explosion-proof [Ex ia] IIC or [Ex ib] IIC electrical device
and should always be used outside potentially explosive areas (in a safe area). Only electrical circuits,
certified as intrinsically safe, can be connected to other intrinsically safe circuits in the Ex zone.
Before operation, the intrinsic safety must be verified for the SIL O2 oxygen analyzer circuit connected
to the circuit of other equipment, including the interconnecting cabling.
The data contained in the EC test certificate and the regulations of EN 60079-14: 2011-10 must be
observed.
The Sensors are ATEX rated devices and have certain conditions of use assigned.
Note. Non-Atex (Ex) Sensors variants of the models listed in the manual may also be used with the
SIL O2 Analyser as long as they are installed in a Non-ATEX (Ex) or ‚Safe‘ area or zone.
For Acetal-bodies Sensors, the following instructions apply;
The Sensor should be installed in such a way that it is not subject to impact by other objects and should
not be located close to additional heat sources. Note the ambient temperature range as it appears on the
Sensor labelling.
Care must be taken when installing equipment with plastic enclosures or plastic parts of enclosures to
ensure that the equipment is protected from any situations that could cause a build up of static charge. The
equipment must not be installed into locations in which it could come into contact with, through normal
or abnormal circumstances, fast moving dust laden air/gas or non-conductive fluids. The equipment must
be cleaned only with a damp cloth.
