VEGAPULS 67 • 4 … 20 mA/HART - four-wire
36532-EN-160224
7. Connect the screen to the internal ground terminal, connect the
outer ground terminal to potential equalisation in case of power
supply via low voltage
8. Connect the lead cable for power supply in the same way accord-
ing to the wiring plan, in addition connect the ground conductor to
the inner ground terminal when powered with mains voltage.
9. Tighten the compression nut of the cable glands. The seal ring
must completely encircle the cables
10. Screw the housing lid back on
The electrical connection is finished.
Information:
The terminal blocks are pluggable and can be removed from the
housing insert. To do this, lift the terminal block with a small screwdriv-
er and pull it out. When inserting the terminal block again, you should
hear it snap in.
