The electrode relay (K1) must meet the following requirements:
▪
Sensor circuit 10 to 30V ~
▪
Tripping current 0.5 to 3 mA
(equivalent to a tripping resistance of 3 to 60 k

Fig. 6: a) Wiring of the electrode relay and b) Position of the leakage sensor
The submersible mixers have a leakage chamber between the oil chamber and the
gear unit which can be fitted with a leakage sensor. A leakage sensor detects fluid in
the leakage chamber resulting from a mechanical seal defect. The leakage sensor has
a separate cable for connection to an electrode relay. Tripping of the electrode relay
must result in the submersible mixer cutting out.

5.4.2 Connection to power supply
DANGER
Electrical connection work by unqualified personnel
Danger of death from electric shock!
▷
Always have the electrical connections installed by a trained electrician.
▷
Observe regulations IEC 30364 (DIN VDE 0100) and, for explosion-proof models,
IEC 60079 (DIN VDE 0164).
WARNING
Incorrect connection to the mains
Damage to the mains network, short circuit!
▷
Observe the technical specifications of the local energy supply companies.
CAUTION
Improper routing of power cable
Damage to the power cable!
▷
Never move the power cable at temperatures below - 25 °C.
▷
Never kink or crush the power cable.
▷
Never suspend the submersible mixer by its power cable.
