Operating Instructions
Intended use
This device fulfills the directive 2014/34/EC and can be applied in explosion hazardous areas according to EN60079-0,
EN60079-11 and EN61241-11 as associated equipment for connection to intrinsically safe flow sensors.In order to en-
sure 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 gas-atmospheres and category (1) D, electrical equip-
ment for dust atmospheres)
Marking (see device or technical data sheet)
ÉII (1) G [Ex ia Ga] IIC T4 acc. to EN60079-11 and EN60079-0/61241-11 and ÉII (1) D [Ex ia Da] IIIC
ÉII 1 G and EEx ia IIC T4 acc.to EN50020 and EN50284 and ÉII 1 D IP67 T 115°C acc.to EN50281-1-1
Local admissible ambient temperature
-25…+70 °C
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 ex-
plosion hazardous areas.Please verify that the classification and the marking on the device comply with the actual
application conditions.
This device is accessory equipment which features intrinsically safe circuits as well as non-intrinsically safe circuits.
It may only be installed outside the explosion hazardous area in dry, clean and well monitored areas. If a declaration
of conformity or declaration of the manufacturer as a category 3 device exists, the device may be installed in zone 2.
Special conditions for safe operation must be observed. Intrinsically-safe electrical equipment can be connected to
the intrinsically-safe connections. All equipment must comply with the demands for operation in the existing zone of
the explosion hazardous area. If the intrinsically safe circuits lead to the dust explosion hazardous zones 20 or 21, it
is important to ensure that the devices connected to this circuit fulfil the demands for category 1D or 2D and are cer-
tified accordingly. If the equipment is interconnected, it is necessary to perform the "Proof of intrinsic safety" (EN
60079-14). Equipment which has been used once to connect intrinsically safe circuits to non-intrinsically safe circuits
is no longer suitable for subsequent use with intrinsically safe circuits. Relevant regulations exist for the establish-
ment of intrinsically-safe circuits, mounting of external connection parts as well as the characteristics and laying of
cables. Cables and terminals with intrinsically-safe circuits must be marked. They should be separated from non-in-
trinsically safe circuits or must feature appropriate insulation (EN 60079-14). Observe the prescribed clearances to
earthed components and connections of other devices to the intrinsically-safe connections of this device. Unless ex-
pressed specifically in the device-specific operating instructions, the approval becomes void if the device is opened,
repaired or actions are performed on the device by someone other than approved experts or the manufacturer. Visi-
ble changes to the device housing, such as brown-black discolourations caused by heat, as well as holes or bulges
also indicate a serious danger. Switch off the device immediately. With the associated electrical equipment the in-
terconnected intrinsically-safe equipment must also be checked. Inspection of a device with regard to the explosion
protection can only be performed by an expert or the manufacturer. The operation of the devices is only permitted in
conjunction with the permitted data printed on the side of the housing. Before any commissioning or modification of
the device interconnections, ensure that the respective regulations, directives and conditions have been complied
with and also ensure that use is only for the intended purpose and the safety requirements have been fulfilled.After
connection to other circuits the sensor may no longer be used in Exi installations. When interconnected to (associat-
ed) electrical equipment, it is required to perform the "Proof of intrinsic safety" (EN60079-14).
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-mag-
netic fields.The pin configuration and the electrical specifications can be taken from the device marking or the tech-
nical 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.
Special conditions for safe operation
The device must be protected against any kind of mechanical damage.
