5.3 Installation, Cable connections
All cable connections should be done as shown in the
connection diagrams (see section 9). Break the seal in the
control unit cable access hole as seen in illustration a, insert
the cable as shown in b, and connect to the properly connec-
tion terminal as shown in c. When the connection is comple-
te be sure to properly secure the plastic nut by hand – see il-
lustration d.
If a potential free contact is to be installed, please follow the
technical information supplied with that part.
The cable access ports at the base of the control unit
which are not used should remain as they are and the
protective seal should not be pierced.
The pre-installed motor and level sensor cables have a stan-
dard length of 5 meter. The motor cable can be extended to
a maximum length of 20 meters only with the use of a VDE
approved extension connection.
The transparent air hose on the level sensor transfers air

important points concerning this follow:
- This air hose must be laid with a continuous slope to the
control unit. The hose should not be kinked, coiled, loo-

- Not following the above requirements can lead to
improper pressure readings resulting in improper
pump operations!
Caution!
Pressure switch cable must be layed with a constant
downward slop to the lifting station. The cable should
