!
The instrument is not suitable for installation in areas with an
explosion hazard.
!
Any electrical connection which deviates from the connection
diagram may result in the destruction of the instrument.
!
In supply networks that are subject to interference (e.g. thyristor
control units), the instrument should be supplied from an isolat-
ing transformer.
!
Supply fluctuations are only permissible within the specified

tolerances

Setup interface
A
The setup interface and the analog output are not electrical-
ly isolated. This means that under adverse conditions, with
a built-in transmitter, equalizing currents may flow when
connecting the PC interface. These equalizing currents may
result in damage to the instruments connected.
No danger arises if the output circuit of the transmitter is
isolated from ground. If it has not been assured that the out-
put circuit on a built-in transmitter is electrically isolated,
one of the following safety measures must be taken:
Use a PC without galvanic coupling to ground (e.g. a note-
book in battery operation), or disconnect the output of the
transmitter before connecting the PC interface.
