WARNING!
Physical injuries and damage to property and the
environment caused by components blowing out in
the event of a failure
In the event of a failure, either the plug of the blow-out
device or, in case of instruments with safety version "S3",
the entire case back is ejected.
Due to the high energy of the components blown out in
the event of a failure and the media that can subsequent-
ly escape, the possibility of physical injuries and damage
to property exists.
▶
It must be ensured, e.g. by suitable protective devices
or sufficient distance, that in the event of a failure
neither personal injury nor damage to property or the
environment can occur.
5.1 Requirements for the installation location
If the line to the measuring instrument is not adequately stable, an
„
instrument mounting bracket should be used for fastening.
If vibrations cannot be avoided by means of suitable installation,
„
instruments with case filling should be used.
For outdoor applications, the selected installation location has to
„
be suitable for the specified ingress protection, so that the instru-
ment is not exposed to impermissible weather conditions.
In order to avoid any additional heating, the instruments must not
„
be exposed to direct solar irradiation while in operation!
To ensure that the pressure can be safely vented in the case of a
„
failure, a minimum distance of 20 mm [7,9"] from any object must
be maintained.
5.2 Mounting
After unpacking the instrument, a visual inspection for damage
„
(e.g. pointer, threads, sealing face, pressure port) must be carried
out.
