Use of the transponder in hazardous areas for dusts
The equipment is suitable for dusts whose ignition temperatures for a dust layer of 5 mm are
higher than 210 °C (smoldering temperature). The ignition temperature specified here
according to EN 60079-0: 2012 + A11: 2013 for ignition protection type ic in this case
references the smoldering temperature of a layer of combustible flyings (ic IIIA) or
alternatively non-conductive dusts (ic IIIB).
Temperature class grading for dusts with up to 2000 mW ERP
If the radiated power of an antenna radiating into the hazardous area or located in the
hazardous area and operating in the 865 - 868 MHz frequency band cannot exceed the
value 2000 mW, the temperature class grading is as follows:
Table 7- 23 Temperature class grading for dusts
Ambient temperature range

WARNING
Ignitions of dust-air mixtures
When using the RF610T transponder, make sure that the temperature values are adhered
to in keeping with the requirements of the area of application.
Non-compliance with the permitted temperature ranges while using the transponder can
lead to ignitions of dust-air mixtures.
