Circuit diagram for 12 / 24 volt systems, standard version
The electrical connection has to be done by a professional installer.
Attention: Connection feed pump: red = positive (+), black = negative (-). Wrong
polarity destroys the pump and is not covered by warranty.

S1 Switch feed pump (LP)
S2 Switch relay high-pressure pump (HP)
F1 Fuse for control and feed pump 5 A
F2 Fuse for high-pressure pump 50 A
Supply line for the switches feed pump and relay
control 1,5 to 2,5 mm²
The required cross section in mm² refers to the
cable total length which results from the addition
of the plus and minus cable lengths.
Connecting cables and fuses are not included in scope of delivery.
Switches in the control panel and the high current relay are included.
As the output power of the plant depends on the tension of the driving motor, in the
calculation of the wire cross sections a voltage drop of only appr. 2% should be
estimated to provide for the maximum continuous output.
