6. Electrical Connection
Important!
To be connected by a qualified electrici-
an only. Comply with the relevant, cur-
rently valid regulations, laws and stan-
dards. Also read and follow the "Safety
Instructions" chapter. The seals of the
cable glands which are not used, i.e. no
cable is connected through them, may
not be penetrated. They help to seal the
housing.
The connection lead of the ultrasound sen-
sor must be connected in accordance with
the circuit diagram (see next page). First,
use a screwdriver to push through the cable
gland seal concerned (Figure a), feed
through the cable (Figure b) and connect
(Figure c).
Then tighten the nut of the cable gland by
hand (Figure d).
Note the technical specifications when
connecting the drinking water top-up supp-
ly, outputs 1 and 2, the floating contact and
the leakage probe. Use products approved
by the manufacturer only. Otherwise the
above text applies.
Do not penetrate the seals of the cable
glangs which are not used, i.e. through
which a cable is not connected. They
help to seal the housing
