LEVEL TRANSMITTER 8185 - 4 ... 20 mA/HART
Take note of the corresponding installation regulations for Ex
applications. In particular, make sure that no potential equal-
isation currents flow over the cable screen. In case of
grounding on both sides this can be achieved by the use of a
capacitor or a separate potential equalisation.

5.2 Connection procedure

Proceed as follows:
1 Unscrew the housing cover
2 If an indicating and adjustment module is installed, remove
it by turning it slightly to the left.
3 Loosen compression nut of the cable entry
4 Remove approx. 10 cm (4 in) of the cable mantle, strip
approx. 1 cm (0.4 in) insulation from the ends of the
individual wires
5 Insert the cable into the sensor through the cable entry
6 Lift the opening levers of the terminals with a screwdriver
(see following illustration)
7 Insert the wire ends into the open terminals according to
the wiring plan
8 Press down the opening levers of the terminals, you will
hear the terminal spring closing
9 Check the hold of the wires in the terminals by lightly
pulling on them
10 Connect the screen to the internal ground terminal and the
external ground terminal to potential equalisation
11 Tighten the compression nut of the cable entry. The seal
ring must completely encircle the cable
12 Screw the housing cover back on
The electrical connection is finished.
