2.2 Operator’s responsibility
Safety instructions for proper operation of the device must be respected. They are to be provided by the operator for
use by the respective personnel for installation, servicing, inspection and operation. Risks from electrical energy and
from the released energy of the medium, from escaping media and from improper connection of the device must be
eliminated. The details for this are to be found in the corresponding applicable set of regulations, such as DIN EN,
UVV (accident prevention regulations) and in sector-specific instances of use (DVWG, Ex-. GL, etc.) the VDE
guidelines and the regulations supplied by local utilities companies.
The device must be taken out of service and secured against inadvertently being restarted, if the presumption is that
risk-free operation is no longer possible (see Chapter 10: Faults).
Conversion works or other technical alterations to the device by the customer are not permitted. This also applies to
installation of spare parts. Possible conversations or alterations may only be carried out by the manufacturer.
The operational safety of the device is only guaranteed where it is used for its intended purpose. The specification of
the device must be adapted to the medium used in the plant. The limit values indicated in the technical data must not
