For the wiring of the level sensor, you need a two - core unshielded cable, which is termi-
nated inside the sensor head of the level sensor.
It is essential that the correct cross section be selected: the supply voltage at the level se n-
sor must not fall below 8 V in the event of maximum current consumption (21.5 mA).
To connect the level sensor (see Figure 4):
(1) Unscrew cap (1) using an open - ended spanner (SW 19)
(2) Loosen union nut (2) of screwed cable gland (3)
