Installation notes
Setup interface
!
The choice of cable, the installation and the electrical connec-
tion must conform to the requirements of VDE 0100 “Regula-
tions on the Installation of Power Circuits with nominal voltages
below 1000V”, or the appropriate local regulations.
!
The electrical connection, as well as work inside the instrument,
must only be carried out by properly qualified personnel.
!
Ensure that the instrument is completely isolated from the sup-
ply before carrying out work where live components may be
touched.
!
A current limiting resistor (safety function) interrupts the supply
circuit in the transmitter in the event of a short-circuit. The ex-
ternal fuse of the supply should not be rated above 1A (slow).
!
Avoid magnetic or electric fields, such as caused by transform-
ers, mobile phones or electrostatic discharge, in the neighbor-
hood of the instrument
1
.
!
Do not install inductive loads (relays, solenoid valves etc.) in the
vicinity of the instrument; use RC networks, spark quenchers or
freewheel diodes for interference suppression.
!
Run input, output and supply lines separately, and not parallel
to each other. Route cable pairs close together and twisted, if
possible.

The setup interface and the analog out-
put are not electrically isolated.
