Safety guidelines
1.1
General Information
This operating manual contains in-
structions fundamental to the installa-
tion, operation and maintenance of
the instrument that must be observed
unconditionally. It must be read by the assembler,
operator and the specialized personnel in charge of
the instrument before it is installed and put into op-
eration. This operating manual must be kept in an
easily accessible place at the installation site.
The subsequent sections on general safety instruc-
tions (1.2 - 1.7) as well as the following special in-
structions about assembly in particular, commis-
sioning and maintenance (2 to 10) contain im-
portant safety instructions, the non-observance of
which can endanger persons, animals and physical
objects.
1.2
Personnel Qualification
Staff assigned to assembly, operating, maintenance
and inspection tasks shall be adequately qualified
for this work and must be sufficiently instructed and
trained to meet the requirements of assembly, op-
erating, maintenance and inspection work.
1.3
Risks due to Non-Observance of
Safety Instructions
Non-observance of these safety instructions, the in-
tended use of the device or the limit values given in
the technical specifications can be hazardous or
cause harm to persons, the environment or the
plant itself. Fischer Mess- und Regeltechnik GmbH
will not be liable for damage claims if this should
happen.
1.4
Safety Instructions for the Operating
Company and the Operator
The safety instructions on correct operation of the
instrument must be observed. The operating com-
pany must make them available to the installation,
maintenance, inspection and operating personnel.
Dangers arising from electrical components, energy
discharged by the medium, escaping medium and
incorrect installation of the instrument must be elim-
inated. The particulars can be found in the respec-
tive regulations such as DIN, EN, accident preven-
tion regulations (UVV) and - for industry-specific in-
dividual applications - also in the industry guidelines
issued by the DVWG, Ex, GL, etc. as well as VDE
and local EVUs.
