Safety information
WARNING! NOTICE! NOTES!
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 operating 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 > 7 V DC is accidentally applied to the incremental analog
output signals SIN+, SIN-, COS+, COS-, Ref+ or Ref-, the measuring system
must be checked at the factory, stating the reasons or circumstances. The
measuring system must be taken out of operation 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 re-
sponsible 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.
The use of the devices as a step, etc. is not intended use.
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.
In case of storage as well as in the operation of the measuring system unused
connecting plugs have to be provided either with a mating connector or with a
protective cap. The IP protection class is to be selected according to the re-
quirements.
