Protection by enclosure "tc" Some of the information in this instruction manual is more specific than the information provided in the datasheet.
GeneralThe 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, commissioningLaws 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!
MaintenanceNo changes can be made to apparatus, which are operated in hazardous areas.
Repairs to these apparatus are not possible.
Special conditions
Maximum operating current ILThe maximum permissible load current must be restricted to the values given in the following list.
High load currents and load short-circuits are not permitted.
Maximum operating voltage UBmaxThe maximum permissible operating voltage UBmax must be restricted to the values given in the following list. Tolerances are not permitted.
Maximum permissible ambient temperature TUmaxdependant of the load current IL and the max. operating voltage UBmax
Information can be taken from the following list.
at UBmax=30 V, IL=150 mA47 °C (116.6 °F)
at UBmax=30 V, IL=100 mA51 °C (123.8 °F)
at UBmax=30 V, IL=50 mA53 °C (127.4 °F)
Protection from mechanical dangerThe sensor must not be exposed to ANY FORM of mechanical danger.
Protection from UV lightThe 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 chargeElectrostatic 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 connectorThe 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)
