ceramic capacitor (e.g. 1 nF, 1500 V). Low-frequency potential equali-
sation currents are thus suppressed, but the protective effect against
high frequency interference signals remains.
5.2 Connecting
The voltage supply and signal output are connected via the spring-
loaded terminals in the housing.
The connection to the indicating and adjustment module or to the
interface adapter is carried out via contact pins in the housing.
Information:
The terminal block is pluggable and can be removed from the elec-
tronics. To do this, lift the terminal block with a small screwdriver and
pull it out. When inserting the terminal block again, you should hear it
snap in.
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) of insulation from the ends of the individual wires
5. Insert the cable into the sensor through the cable entry

6. Insert the wire ends into the terminals according to the wiring plan
Information:
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 head with a small screwdriver;
the terminal opening is freed. When the screwdriver is released, the
terminal closes again.
