  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.pepperl-fuchs.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 : 61 °C (141.8 °F)
• using an amplifier in accordance with EN 60947-5-6 : 61 °C (141.8 °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.
• Protection of the connection cable : The connection cable must be prevented from being subjected to tension and torsional loading.
• 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.
