Use of the MDS D124 in hazardous area

The mobile data memory 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 requirements of the directive 94/9/EC are met by the use of the following standards:
EN 60079-0:2009, EN 60079-11:2007, EN 61241-11:2006 and EN 60079-26:2007
When used in hazardous areas, the MDS D124 must not be operated with field strengths > 5
A / m to avoid impermissible heating. This is not the case with readers from the SIMATIC RF
range (MOBY D, RF200 and RF300).
