2.9 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 overvoltages of >7 V DC are inadvertently applied at the incremental
analog output signals SIN+, SIN–, COS+, COS–, Ref+ or Ref–, the
measuring system must be inspected at the factory, with specification
of the reasons or circumstances. The measuring system must be shut
down immediately.
– 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.
– 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.
– When storing and operating the measuring system unused connection
plugs must either be provided with a mating plug or a protective cap.
The appropriate IP protection class must be selected to meet the
relevant requirements.
– 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.
