Operating Instructions
Intended use
This device fulfills the directive 2014/34/EC and is suited for use in explosion hazardous areas according to EN
60079-0:2012 + A11 and EN 60079-11:2012.Further it is suited for use in safety-related systems, including SIL2 as per IEC
61508.In order to ensure correct operation to the intended purpose it is required to observe the national regulations and
directives.
For use in explosion hazardous areas conform to classification
II 1 G and II 1 D (Group II, Category 1 G, electrical equipment for gaseous atmospheres and category 1 D, electrical equipment for
dust atmospheres).
Marking (see device or technical data sheet)
É II 1 G and Ex ia IIC T6 Ga and É II 1 D Ex ia IIIC T95 °C Da acc. to EN 60079-0, -11
Local admissible ambient temperature

Installation/Commissioning
These devices may only be installed, connected and operated by trained and qualified staff. Qualified staff must have
knowledge of protection classes, directives and regulations concerning electrical equipment designed for use in
explosion hazardous areas.Please verify that the classification and the marking on the device comply with the actual
application conditions.
This device is only suited for connection to approved Exi circuits according to EN 60079-0 and EN 60079-11. Please
observe the maximum admissible electrical values.After connection to other circuits the sensor may no longer be
used in Exi installations. When interconnected to (associated) electrical equipment, it is required to perform the "Proof
of intrinsic safety" (EN60079-14).Attention! When used in safety systems, all content of the security manual must be
observed.
Installation and mounting instructions
Avoid static charging of cables and plastic devices. Please only clean the device with a damp cloth. Do not install the
device in a dust flow and avoid build-up of dust deposits on the device.If the devices and the cable could be subject to
mechanical damage, they must be protected accordingly. They must also be shielded against strong electro-magnetic
fields.The pin configuration and the electrical specifications can be taken from the device marking or the technical
data sheet.In order to avoid contamination of the device, please remove possible blanking plugs of the cable glands or
connectors only shortly before inserting the cable or opening the cable socket.
Service/Maintenance
Repairs are not possible. The approval expires if the device is repaired or modified by a person other than the
manufacturer. The most important data from the approval are listed.
