VEGA VEGAVIB 55 - double relay (DPDT) - Manual (Page 14)

5 Connecting to voltage supply
5.1 Preparing the connection
Generally note the following safety instructions:
l
Connect only in the complete absence of line voltage
Connect the power supply according to the following diagrams.
Oscillator VB60R is designed in protection class 1. To maintain
this protection class, it is absolutely necessary that the ground
conductor is connected to the internal ground terminal. Take
note of the general installation regulations. As a rule, connect
VEGAVIB 55 to vessel ground (PA), or in case of plastic
vessels, to the next ground potential. On the side of the
housing there is a ground terminal between the cable entries.
This connection serves to drain off electrostatic charges.
The data for power supply are stated in chapter "Technical
data" in the "Supplement".
VEGAVIB 55 is connected with standard cable with round
cross section. An outer cable diameter of 5 ... 9 mm (0.2 ...
0.35 in) ensures the seal effect of the cable gland.
If cable with a different diameter or wire cross section is used,
exchange the seal or use an appropriate cable connection.
5.2 Connection procedure
Proceed as follows:
1 Unscrew the housing cover
2 Loosen compression nut of the cable entry
3 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
4 Insert the cable into the sensor through the cable entry
5 Lift the opening levers of the terminals with a screwdriver
(see following illustration)
6 Insert the wire ends into the open terminals according to
the wiring plan
7 Press down the opening levers of the terminals, you will
hear the terminal spring closing
8 Check the hold of the wires in the terminals by lightly
pulling on them
