7. Wiring details
Electrical connection of this pressure transmitter is made via an L-plug connec-
EN
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:
U + Plus terminal for supply voltage
B
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 2 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 3 to 6 or 4 to 6 (for the 3-wire version), must remain
free and must not be used as connection points (also see Chapter 10 "Technical
data").

(display/recorder)
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 12 V, or below 14 V for the Ex-version.
