Please note:
– Wiring work should only be carried out when the supply voltage is
switched off; the same applies when opening and closing electrical
connections.
– Do not undertake any welding operations if the measuring system is
already wired / switched on.
– An appropriate heating/cooling measure should be used at the
installation site to prevent the ambient temperature exceeding or falling
below the permitted limit values.
– The measuring system must be installed so that direct moisture cannot
affect the measuring system.
– Appropriate ventilation/venting or heating/cooling measures at the
installation site must prevent values falling below the dew point
(condensation).
– If an overvoltage of >36 VDC is applied inadvertently, the measuring system
must be inspected on site and the reasons/circumstances stated.
– Checks must examine the potential hazards arising from interaction
with other systems and devices which are or will be installed in the
vicinity. It is the user's responsibility to take appropriate measures.
– The supply voltage must be protected with a fuse appropriate for the
cable cross section.
– Cables must be suitable for the relevant temperature range.
– The measuring system should not be operated if it is defective.
– Ensure that the installation environment is protected from aggressive
media (acids etc.).
– Shocks to the shaft (e.g. hammer blows) should be avoided during
installation.
– The measuring system must not be opened.
– The nameplate specifies the technical properties of the measuring
system. If the nameplate is no longer legible or is missing altogether,
the measuring system must no longer be put into service.
