I.4. Electrical Connection.
The system comes equipped with an electrical motor for the low-pressure pump 12/24V
DC at 2000 rpm. It must be connected using the moisture shielded cable with a cross-
section appropriate for the distance between the batteries and the motor. The
recommended cables are the following ones:
Model / Power nominal motor
60 Litters/550watios
90 Litters/750watios
Batteries / Power Box Dist.
12 v DC
24 v DC

These sections are appropriate to prevent voltage losses greater than 1.6% of the rated
voltage (0.2 V in 12 V DC).
A distance of more than 3 meters between the power box and the electric motor in the
low pressure pump must never be exceeded. For longer distances than the ones provided
in this table, please contact the manufacturer.
•
Connect the two wires from the breaker with the corresponding power box
terminals marked as power supply (20) as indicated in scheme of (Chapter I Page
6).
•
Connect the motor-pump terminals (4) with the ones marked as “Pump” in the
power box.
•
Also a 4-wire 3 meter long cable is supplied with the motor, it comes connected to
the electro-valve and the pressure switch by one of its ends, this end of the cable
must be passed through the seals of the box and connected to their respective
terminals.
•
Connect the control panel (21) and the head (20), using the supplied 6 meter cable
with red connectors RJ-45 (Ethernet) at both ends, taking care to connect one of
them to the plug marked as POWER STAGE. The remote control panel (23)
OPTIONAL must be connected to the plug marked as REMOTE using the 10
meter cable
•
Make sure the pump’s direction of rotation is the correct one, marked by the water
inlet and the outlet, if it isn’t, reverse the polarity on the motor
connection.(Chapter I Page 6 )
As a general rule, the electric grid circuit should be properly protected, taking care
to oversize the connection cables to avoid voltage drops and unnecessary power
consumption.
