Store the instrument in its original packaging in a location that fulfils the conditions listed above. If
the original packaging is not available, pack and store the instrument as described below:
1. Wrap the instrument in an antistatic plastic film.
2. Place the instrument, along with shock-absorbent material, in the packaging.
3. If stored for a prolonged period of time (more than 30 days), place a bag, containing a
desiccant, inside the packaging.
WARNING!
Before storing the instrument (following operation), remove any residual media. This
is of particular importance if the medium is hazardous to health, e.g. caustic, toxic,
carcinogenic, radioactive, etc.
6. Commissioning, operation
WARNING!
When the thermometer is mounted, the temperature must not drop below the allowed
operating temperature (environment, medium) or exceed it, even when taking
convection and heat radiation into account!
WARNING!
Thermometers must be earthed if dangerous voltages could be expected at the
connection wires (caused, for example, by mechanical damage, electrostatic
discharge or induction)!
6.1 Electrical connection
CAUTION!
■ Damage to cables and wires, and to connection points, must be avoided
■ Provide finely stranded conductor ends with end splices (cable assembly)
■ Both the internal capacitance and inductance must be considered
For the electrical connections of thermometers (e.g. connection circuit diagrams, tolerance values,
etc.), please refer to the appropriate data sheets. If head transmitters or digital displays have been
built into the connection housing, these data sheets must also be given proper consideration.
