Effective internal inductivity Ci ≤ 120 nF ; a cable length of 10 m is considered. Effective internal inductance Li ≤ 50 µ H ; a cable length of 10 m is considered. General The apparatus has to be operated according to the appropriate data in the data sheet and in this instruction manual. The EC-Type Examination Certificate has to be observed. The special conditions must be adhered to! Directive 94/9/EG and hence also EC-Type Examination Certificates apply in general only to the use of electrical apparatus under atmospheric conditions. The use in ambient temperatures of > 60 °C was tested with regard to hot surfaces by the mentioned certification authority. If the equipment is not used under atmospheric conditions, a reduction of the permissible minimum ignition energies may have to be taken into consideration. Ambient temperature Details of the correlation between the type of circuit connected, the maximum permissible 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 11271 has already been applied to the temperature table for category 1. Installation, commissioning Laws and/or regulations and standards governing the use or intended usage goal must be observed. The intrinsic safety is only assured in connection with an appropriate related apparatus and according to the proof of intrinsic safety. The associated apparatus must satisfy the requirements of category ia. Due to the possible danger of ignition, which can arise due to faults and/or transient currents in the equipotential bonding system, galvanic isolation of the power supply and signal circuit is preferable. Associated apparatus without electrical isolation must only be used if the appropriate requirements of IEC 60079-14 are met. If the Exrelated 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. Maintenance No changes can be made to apparatus, which are operated in hazardous areas. Repairs to these apparatus are not possible. **Special conditions** The connecting parts of the sensor must be set up in such a way that degree of protection IP20, in accordance with lEC 60529, is achieved as a minimum. Protection from mechanical danger When using the device in a temperature range of -60 °C to -20 °C, protect the sensor against the effects of impact by installing an additional enclosure. The information regarding the minimum ambient temperature for the sensor as provided in the datasheet must also be observed. Electrostatic charge Electrostatic charges must be avoided on the mechanical housing components. Dangerous electrostatic charges on the mechanical housing components can be avoided by incorporating these in the equipotential bonding.

**Equipment protection level Dc (tc)** Instruction **Manual electrical apparatus for hazardous areas Device category 3D** for use in hazardous areas with combustible dust Certificate of Compliance PF 15CERT3774 X CE marking ATEX marking ¬ II 3D Ex tc IIIC T80°C Dc The Ex-related marking can also be printed on the enclosed label. Directive conformity 94/9/EG Standards EN 60079-0:2012+A11:2013, EN 60079-31:2014 Protection by enclosure "tc" Some of the information in this instruction manual is more specific than the information provided in the datasheet. General The corresponding datasheets, declarations of conformity, EC-type examination certificates, certifications, and control drawings, where applicable (see datasheets), form an integral part of this document. These documents can be found at www.pepperlfuchs.com. The maximum surface temperature of the device was determined without a layer of dust on the apparatus. Some of the information in this instruction manual is more specific than the information provided in the datasheet. Installation, commissioning Laws and/or regulations and standards governing the use or intended usage goal must be observed. 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! Maintenance No changes can be made to apparatus, which are operated in hazardous areas. Repairs to these apparatus are not possible. **Special conditions** Minimum series resistance RV A minimum series resistance RV is to be provided between the power supply voltage and the proximity switch in accordance with the following list. This can also be assured by using a switch amplifier. Maximum operating voltage UBmax The maximum permissible operating voltage UBmax must be restricted to the values given in the following list. Tolerances are not permitted. Maximum permissible ambient temperature TUmax Values can be obtained from the following list, depending on the max. operating voltage Ub max and the minimum series resistance Rv. at UBmax=9 V, RV=562 Ω 58 °C (136.4 °F) using an amplifier in accordance with EN 60947-5-6 58 °C (136.4 °F) Protection from mechanical danger The sensor must not be exposed to **ANY FORM** of mechanical danger. Protection from UV light The sensor and the connection cable must be protected from damaging UV-radiation. This can be achieved when the sensor is used in internal areas. Electrostatic charge Electrostatic charges must be avoided on the mechanical housing components. Dangerous electrostatic charges on the mechanical housing components can be avoided by incorporating these in the equipotential bonding. Do not attach the nameplate provided in areas where electrostatic charge can build up. Plug connector The plug connector must not be withdrawn under voltage. The proximity switch is identified as follows: "WARNING - DO NOT SEPARATE WHEN ENERGIZED".  With the plug connector disconnected, soiling of the internal area must be prevented.(i.e. the area that is inaccessible when the connector is inserted)
