7. Wiring details
Electrical connection of this pressure transmitter is made via an L-plug connec-
tor. Precise wiring diagrams can be found in the following drawings. In addition
to the wiring details, output signal and required power supply are given on the
rating plate.
Description of terminal designations used:

B
+ Plus terminal for supply voltage
0 V Minus terminal for supply voltage
Sig+ Plus terminal for output signal
Sig- Minus terminal for output signal
The instruments must be included within the plant’s equipotential bonding
Terminal assignment
Terminals 1 and are the terminals for the signal output and for the power
supply. The terminal marked with PE (protective earth) is connected internally
to the housing. The connections to 6 or 4 to 6 (for the -wire version), must
remain free and must not be used as connection points (also see Chapter 10
"Technical data").
2-wire design 3-wire design
i.e. 4 ... 20 mA i.e. 0 ... 20 mA / 0 ... 10 V

An unstabilised DC voltage, with a residual ripple of max. 10 % peak-to-peak in
the range of the indicated supply voltage limits, is sufficient as a power supply.
Make sure that the supply voltage applied exceeds the maximum required
voltage by at least the value of the voltage drop across the external display
or evaluation devices; i.e. the transmitter can operate using a non-stabilised
supply voltage within the given limits, so long as the voltage available to the
transmitter does not fall below 1 V, or below 14 V for the Ex-version.
