product.
Specialized personnel are persons who can assess
the work they have been assigned and recognize
potential dangers by virtue of their specialized train-
ing, their skills and experience and their knowledge
of the pertinent standards.
1.3
Risks due to Non-Observance of
Safety Instructions
Non-observance of these safety instructions, the in-

Dangers arising from electrical components, energy
discharged by the medium, escaping medium and
incorrect installation of the instrument must be elim-
inated. For more information, please see the appli-
cable national and international regulations.
In Germany these are the DIN EN, UVV regula-
tions, specific industrial guidelines such as DVGW,
Ex, GL, etc., the VDE- regulations and the regula-
tions of the local energy supply companies.
