Safety notes for Zone 0:
8) Potentially explosive vapour/air mixtures may arise under atmospheric conditions only:
If no potentially explosive mixtures are present, or if additional protective measures have been taken, e.g. EN 1127-1,
the transmitters may be operated under other than atmospheric conditions in accordance with the manufacturer's
specifications.
9) The antenna may be only employed in those media, for which the wetted parts are known to be suitable.
10) The construction of the transmitter renders unnecessary any additional overvoltage protection for plants that must be
protected against risk of ignition through lightning in accordance with German National Guidelines TRbF 100 No. 8.
11) Associated apparatus with galvanic isolation between the intriniscally safe and non-intrinisically safe circuits are to be
preferred.
