Preparing the connection

Safety instructions
Always keep in mind the following safety inst-
ructions:
Warning:
Connect only in the complete absence
of line voltage.
•
The electrical connection must only be
carried out by trained personnel authorised
by the plant operator.
•
If overvoltage surges are expected, overvol-
tage arresters should be installed.
Voltage supply
Power supply and current signal are carried on
the same two-wire cable. The operating voltage
can differ depending on the instrument version.
The data for power supply are specified in chap-
ter "Technical data".
Keep in mind the following additional factors
that influence the operating voltage:
•
Lower output voltage of the power supply
unit under nominal load (e.g. with a sensor
current of 20.5 mA or 22 mA in case of fault)
•
Influence of additional instruments in the
circuit (see load values in chapter "Technical
data")
Connection cable
The instrument is connected with standard
two-wire cable without screen. If electromagne-
tic interference is expected which is above the
test values of EN 61326-1 for industrial areas,
screened cable should be used.

Make sure that the cable used has the required
temperature resistance and fire safety for max.
