2.11 Safety information
● Destruction, damage and malfunction of the measuring system!
– Only carry out wiring work or opening and closing of electrical
connections with the system de-energized.
– Do not undertake any welding work if the measuring system is already
wired or switched on.
– Falling below or exceeding the permissible ambient temperature limit
values must be prevented through an appropriate heating/cooling
measure at the place of installation.
– The measuring system must be installed so that no direct moisture
can affect the measuring system.
– Suitable aeration/ventilation and heating/cooling measures must be
provided at the place of installation to prevent the temperature falling
below the dew point (condensation).
– If an overvoltage of >36 V DC is inadvertently applied the measuring
system must be inspected in the factory, with specification of the
reasons or circumstances.
– Potential hazards resulting from interactions with other systems and
equipment which are or will be installed in the vicinity must be
checked. The user is responsible for taking appropriate measures.
– The power supply must be
protected with a fuse suitable for the supply
lead cross-section.
– Electromagnetic interference sources can to put out of operation the
safety function of the measuring system. Appropriate measures see
chapter “EMC requirements” on page 84.
– Cables used must be suitable for the temperature range.
– A defective measuring system must not be operated.
– Make sure that the installation environment is protected from
aggressive media (acids etc.).
– Avoid shocks (e.g. hammer blows) to the shaft during installation.
– Opening the measuring system is forbidden.
– The type plate specifies the technical characteristics of the measuring
system. If the type plate is no longer legible or if the type plate is
completely missing, the measuring system must not be operated.
