essential health and safety requirements relating to the design and construction of
equipment and protective systems intended for use in hazardous areas as per Annex II of
the Directive.
The essential health and safety requirements are satisfied in accordance with standards
EN 60079-0: 2012 + A11: 2013 and EN 60079-11: 2012.
This allows the RF640T transponder to be used in hazardous areas for gases, for the device
category 2G and gas group IIB, or alternatively in hazardous areas for dusts, for the device
category 2D and group IIIB.
Note
Readability of the serial number on the type plate
When using the transponder, make sure that the serial number can be read. The serial
number is lasered and can be hidden by paint or other materials making it illegible.
The customer is responsible for making sure that the serial number of a transponder for the
hazardous area can be read at all times.
