Ignitions of gas-air mixtures
The maximum radiated power of the transmitter used to operate the transponder must not
exceed 2000 mW ERP.
Non-compliance with the permitted radiated power can lead to ignitions of gas-air mixtures.
7.8.3.2 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 190 °C (smoldering temperature). The ignition temperature specified here
according to EN 60079-0 and EN 61241-11 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).

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.
