Safety Instructions For Use In Switchgear - WIKA GD-20 Betriebsanleitung

3. Safety
Skilled personnel
Skilled personnel, authorised by the operator, are understood to be personnel who,
based on their technical training, knowledge of measurement and control technolo-
gy and on their experience and knowledge of country-specific regulations, current
standards and directives, are capable of carrying out the work described and indepen-
dently recognising potential hazards.
Special operating conditions require further appropriate knowledge, e.g. of aggressive
media.

3.5 Safety instructions for use in switchgear

WARNING!
Residual media on the dismounted gas density sensor can result in
a risk to persons, the environment and equipment.
▶
Take sufficient precautionary measures.
▶
Aggressive media may be present should a failure occur.
The plant operator must ensure that the handling of SF
a qualified company or by qualified persons who have been specially trained in
accordance with IEC 61634, section 4.3.1 or IEC 60480, section 10.3.1.
Installation and plant status which can lead to the formation of atomic hydrogen in the
connection channel of the transmitter must be completely avoided.
The maximum permissible pressures must be complied with.
