At least once per year the function of the
temperature controlling and temperature
limiting safety device has to be checked and
the surface and connection line should be
inspected for visible damage.
Warning labels and identification labels should
be clearly visible, intact and able to display the
correct information. Products which show
exposed heating conductors or wires, were
overheated. These products have to be
immediately put out of operation and to be
secured against reuse.

There should never be any open or short
circuits amongst the product. Check to ensure
that the system design documentation reflects
the installation and any changes that have
occurred.
Regarding temperature, the products are
manufactured out of special materials with
high demands to chemical and mechanical
stability, which also applies to the power
supply cables.

Repairs may be made only by authorized staff
by origin manufacturer or by enterprises
expressly authorized by this manufacturer.

specification
... the product is not operating at all (no
visible indication of reason)
... the product has been exposed to excessive
strain
... the admissible product limits are exceeded
(e.g. storage, transportation, operating
temperature)
