5. Commissioning, operation
It must be ensured, e.g. by suitable safety 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 point
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 instrument 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 from any object must be
maintained.
5.2 Installation
After unpacking the instrument, a visual inspection for damage (e. g.
„
pointer, threads, sealing face, pressure port) must be carried out.
Depending on the application, the instrument should be filled with the
„
medium before screwing in, in order to ensure it functions properly.
Mounting is only permitted in the depressurised state. Reliably
„
depressurise the instrument using the available valves and protective
devices (e.g. shut-off valve, monoflange).
Nominal position per EN 837-3 / 9.6.6 image 7: 90°±5° ( ⊥ ), if not
„
stated otherwise in the order documentation.
