4 Connecting to power supply

VEGABAR 82 • Slave sensor for electronic differential pressure

46332-EN-160212

4  Connecting to power supply

4.1 Connecting

The connection to the Master sensor is carried out through spring-

loaded terminals in the respective housing. For this, use the supplied, 

confectioned cable. Solid cores as well as flexible cores with cable 

end sleeves are inserted directly into the terminal openings.
In case of flexible cores without end sleeves, press the terminal from 

above with a small screwdriver, the terminal opening is then free. 

When the screwdriver is released, the terminal closes again.

Information:

The terminal block is pluggable and can be removed from the 

electronics. To do this, lift the terminal block with a small screwdriver 

and pull it out. When reinserting the terminal block, you should hear it 

snap in.
You can find further information on the max. wire cross-section under

"

Proceed as follows:
1.  Unscrew the housing lid
2.  Loosen compression nut of the cable gland and remove blind 

plug

3.  Remove approx. 10 cm (4 in) of the cable mantle, strip approx. 

1 cm (0.4 in) insulation from the individual wires or use supplied 

connection cable

4.  Insert the cable into the sensor through the cable entry

5.  Insert the wire ends into the terminals according to the wiring plan
6.  Check the hold of the wires in the terminals by lightly pulling on 

them
