2.7 Special conditions for safe use (X conditions)

Pressure surges must be avoided at all costs. Open the shut-off valves slowly.
„
Temperature increases due to compression warming absolutely must be taken into
„
account. In these cases it may be necessary to throttle the rate of change of pressure or
reduce the permissible medium temperature.
The end user must ensure that the instrument is connected to the equipotential bonding
„
of the end-use application via the process connection. The sealings used at the process
connection must be electrically conductive. Alternatively, take other measures for
grounding.
Avoid handling substances that might react dangerously with the materials of the instru-
„
ment.
Avoid handling substances that are liable to spontaneous combustion.
„
Avoid any kind of external impact. External impacts may generate sparks due to friction
„
processes of different materials.
For instruments with marking pointer, ensure that there are no electrostatic charging
„
mechanisms at the marking pointer.
All accessories (e.g. valves or attachment components) must be assessed in combi-
„
nation with the delivered instruments by the end user. Particularly the requirements of
grounding and prevention of electrostatic charges must be considered.
