Important:
If the measurement data transmitter is installed in Ex-zone 1 the version
SECU-DATA 710M has to be used in combination with the barrier SECU-
DATA 125 (for supplying the SECU-DATA 710M) and the additional diode-
barrier SECU-DATA 710B (for supplying the TRbF-probe in Ex-zone 0) to
achieve the required ignition protection level.
