- 8 -
close to 230 volt or 400-volt cables (minimum separation of 100mm)
If external inductive effects are existed, e.g. from heavy current cables, overhead train
cables, transformer substations, radio and television devices, amateur radio stations,
microwave devices etc, then the cables to the sensors must be adequately shielded.
Sensor cables may be extended to a maximum length of ca. 100 meter, when cable’s
length is up to 50m, and then 0.75mm
2
cable should be used. When cable’s length is up
to 100m, and then 1.5mm
2
cable should be used.

3. Commissioning
Connect the sensors, pumps or switching valves to the controller before you
connect the power supply!
After switching on power to the controller, firstly it will ask for to set the time, password
and parameters of system.
