5.3 Connecting the controller
First of all leave open the wire inputs for the power supply
connection and the connecting wires of the sensors and the pump
in the casing box. For this purpose there are material draws to be
cut out (Illustration 4, Pos.
c
). Each wire input needs two vertical
cuts into the wall of the plastic case. For the cutting you can use
cable stripping knife or an electronic side cutter. The cutting d
should be 2 mm min. from the plastic case ground. Afterwa
the plastic clip can be taken out by moving it back and forth.

controller is open. For this purpose clear the power supply net. Stick to all valid regulations for working
cleared power supply net. Only connect to the power supply net when controller case is closed. Moreover
the user has to take care of the fact that the IP protection is not damaged.

). Each draw can only be
furnished with one connecting wire (up to 2.5 mm2). For
fine-strand wires please use end sleeves for strands. Outsid
the controller the wires must be strain-relieved.
Storing and collector sensor are to be connected
e
to the
prescribed draws (illustration 6, Pos

). In this
context the polarity does not play a role. Outside the
controller the wires must be strain-relieved.
Attention:
Only use original sensors specified for this
