7.4.5 Using the MDS D124 in hazardous areas
The transponder MDS D124, device group II, category 1G or 1D may be installed and
operated in zones 0, 1 and 2 or in the zones 20, 21 and 22.
The following requirements of the 2014/34/EU directive are met:
EN 60079-0:2012 + A11:2013
EN 60079-11:2012
When used in hazardous areas, the MDS D124 must not be operated with transmit power
greater than 2 W or magnetic field strengths > 5 A/m to avoid impermissible heating.
Therefore, the MDS D124 can be operated with the readers RF210R, RF220R, RF240R,
RF250R (incl. all released antennas), RF260R, RF310R, RF340R, RF350R and RF380R.
The MDS D124 transponder is not released for operation with the RF290R reader.
Labeling and warning information
Since neither the Ex marking nor the safety marking can be applied to the MDS D124 for
space reasons, these are supplied on a label. This must be affixed immediately next to the
MDS D124 so that the label clearly relates to the device. The identification of the electrical
equipment as an enclosed unit is:
