• Utilise the instrument within the specified environmental limits of temperatures and
humidity. The instrument is constructed to withstand operation in the following environmental
conditions:
− environmental operating temperature 0°C ÷ +50°C
− storage and transporting temperature -25°C ÷ +65°C

CAUTION
The plant, in which the instrument is introduced, must be constructed according the
operating requirements provided by the current legislation.
The instrument must be perfectly introduced in the plant.
The plant must be operated in full compliance with the provided safety regulations.
Any signals of faults to the power unit should be placed in an area constantly controlled by
operative personnel or plant assistants.
Failure to comply with one of these conditions may cause the unit “logic” to operate in a
potentially dangerous mode for the users of the service.
Therefore, we recommend to the servicing and/or maintenance personnel to operate with
the utmost thoroughness, promptly signalling any variations of the safety parameters, in
order to prevent the development of dangerous conditions or potentially dangerous
conditions.
Because the above explained considerations do not fall under the possibilities of control by
the instrument in the subject, the manufacturer shall not in any way or fashion be held
responsible for any damages that such malfunctions may cause to persons or things.
