For the main formats used in the installation, refer to Fig. 6 and 7.
Applications
Warning
The motor pump must operate without exceeding the pressure limits as shown on the identification

Power connection
Warning
Follow the connection instructions shown in the "Specifications and technical data" paragraph.
• The motor pump power supply must comply with the data indicated on the plate (4): in particular, the power
voltage must not deviate by ± 10 % and the power source must be of a suitable power.
• If the power cable is too short, an extension cable may be used provided it is not longer than 5 m/16 ft and
that the cable section is at least 2.5 mm
• Ensure polarity in the connections (see also Figure 5):
red cable . positive (+);
black cable . negative (-).
• When connecting the motor pump to a battery, proceed as follows:
- if present, disconnect the earth cable;
- connect the red cable to the positive pole (+) of the battery;
- connect the black cable to the negative pole (-) of the battery;
- if present, reconnect the earth cable.
• When disconnecting the motor pump from a battery, proceed as follows:
