2 ATEX 1G Device category 1G II 1G Ex ia IIC T6 T1 Ga Ignition protection "Intrinsic safety" µh ; a cable length of 10 m is considered. and in this instruction manual. The has to be observed. The special conditions must be adhered to! Directive 94/9/EC and therefore the EC-type-examination certificates generally apply only to the use of electrical apparatus under atmospheric conditions. Ambient temperature ambient temperature, the temperature class, and the effective internal reactance values can be found on the EC-type examination certificate. Note: Use the temperature table for category 1!!! The 20 % reduction in accordance with EN has already been applied to the temperature table for category 1. related apparatus and according to the proof of intrinsic safety. The associated apparatus must satisfy the requirements of category ia. Because of the risk of ignition, which can occur due to faults and/or transient currents in the equipotential bonding system, galvanic isolation is preferable in the supply and signal circuits. Associated apparatus without electrical isolation can only be used if the corresponding requirements of IEC are satisfied. Install the device in such a way that the resin surface is not exposed to mechanical hazards. If the Ex-related marking is printed only on the supplied label, then this must be attached in the immediate vicinity of the sensor. The sticking surface for the label must be clean and free from grease. The attached label must be legible and indelible, including in the event of possible chemical corrosion. 2

Install the device in such a way that the resin surface is not exposed to mechanical hazards. If the Ex-related marking is printed only on the supplied label, then this must be attached in the immediate vicinity of the sensor. The sticking surface for the label must be clean and free from grease. The attached label must be legible and indelible, including in the event of possible chemical corrosion. 3

The data stated in the data sheet are restricted by this operating instruction! The special conditions must be observed! must be observed. The sensor must only be operated with energy-limited circuits, which satisfy the requirements of IEC The explosion group complies with the connected, supplying, power limiting circuit. Install the device in such a way that the resin surface is not exposed to mechanical hazards. If the Ex-relevant identification is printed exclusively on the adhesive label provided, this label must be affixed in the immediate vicinity of the sensor! The background surface to which the adhesivelabel is to be applied must be clean and free from grease! The applied label must be durable and remain legible, with due consideration of the possibility of chemical corrosion! 70 C (158 F) 85 C (185 F) 100 C (212 F) 66 C (150.8 F) 81 C (177.8 F) 100 C (212 F) 45 C (113 F) 60 C (140 F) 89 C (192.2 F) 30 C (86 F) 45 C (113 F) 74 C (165.2 F) The sensor must not be mechanically damaged. When used in the temperature range below -20 C the sensor should be protected from knocks by the provision of an additional housing. The connection parts are to be installed, such that a minimum protection class of IP20 is achieved, in accordance with IEC

Directive 94/9/EC and therefore the EC-type-examination certificates generally apply only to the use of electrical apparatus under atmospheric conditions. ambient temperature, the surface temperature, and the effective internal reactance values can be found on the EC-type-examination certificate. The maximum permissible ambient temperature of the data sheet must be noted, in addition, the lower of the two values must be maintained. related apparatus and according to the proof of intrinsic safety. If the Ex-related marking is printed only on the supplied label, then this must be attached in the immediate vicinity of the sensor. The sticking surface for the label must be clean and free from grease. The attached label must be legible and indelible, including in the event of possible chemical corrosion. Electrostatic charge Avoid electrostatic charges that can cause electrostatic discharge when installing or operating the device. Information on electrostatic hazards can be found in the technical specification IEC/TS Do not attach the nameplate provided in areas where electrostatic charge can build up. 5
