Intended usage
This device fulfils the directive 94/9/EC and is suited for use in explosion hazardous areas according to EN50014 and EN50020. In order to ensure cor-
rect 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)
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
-20…+60 °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 explosion 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 con-
nected 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 cir-
cuit fulfil the demands for category 1D or 2D and are certified 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 establishment of intrinsically-safe circuits, mounting of exter-
nal 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-intrinsically 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 expressed 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. Visible 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 interconnected 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 manufactu-
rer. 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.
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 mar-
king or the technical data sheet. In order to avoid contamination of the device, please remove possible blanking plugs of the cable glands or connec-
tors 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.
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.
