2. Safety
8. Permissible vibration load
The instruments should always be installed in locations free from vibration. If the
line to the instrument is not adequately stable, an instrument holder should be
used for fastening.
If necessary, it is possible to isolate the instrument from the mounting point, e.g. by
installing a flexible connection line between the measuring point and the pressure
gauge and mounting the instrument on a suitable bracket.
At the installation site
The following limit values must not be exceeded:
Frequency range: < 150 Hz
Acceleration: < 0.5 g (approx. 5 m/s
9. Cleaning
Clean the equipment with a moist cloth. Do not use other cleaning processes than
manual rubbing to prevent electrostatic charging.
10. Assessment of all accessory components
All accessories (e.g. valves or attachment components) must be assessed in
combination with the delivered instruments by the end user. Particularly the requi-
rements of grounding and prevention of electrostatic charges must be considered.
11. Suitable protective measures
The operator must recognise ignition hazards and take suitable protective measu-
res. See chapter 2.2 "Responsibility of the operator".
12. Description of the protection level
The operator must understand the Ex marking based on the description in chapter
2.6 "Labelling / safety marks" and observe it for their application.
13. Checking of the instrument labelling
The legibility of the marking must be observed during time in use but at least
during inspection periods of three years. See chapter 2.2 "Responsibility of the
operator".
14. Instruments with mark pointer
For instruments with marking pointer, ensure that there are no electrostatic
charging mechanisms at the marking pointer.
