2.1.1 Single pump installation
Figure 1 shows a schematic layout of the hydraulic installation of a pump with inverter.
2.1.2 Multipump installation
Our systems allow the possibility of creating multipump booster sets with coordinated control of all the inverters. The
maximum number of elements that can be connected to create a multipump system is 8. To make use of the
coordinated control function (multi-inverter) it is also necessary to make the required electrical connections to put the
inverters in communication with one another see par. 2.3.6.
A multipump system is used mainly for:
• Increasing hydraulic performance in comparison with a single device.
• Ensuring continuity of operation in the event of a device developing a fault.
• Sharing out the maximum power.
The system is created in a similar way to the single pump system: each pump has its own delivery to its own inverter
and the hydraulic outputs of the inverter all flow into a single manifold.
The manifold must be correctly sized to support the flow created by the pumps that you want to use.
The hydraulic plant must be created as symmetrically as possible to obtain a hydraulic load uniformly distributed over
all the pumps.
The pumps must all be the same and the inverters must all be of the same identical model, connected to each other in
a multi-inverter configuration.

2.2 Electrical connections

The inverter is equipped with cables for the power supply and for the pump, indicated respectively with the labels LINE
and PUMP.
The internal electrical connections are accessible by removing the 4 screws on the cover. The internal terminal boards
have the same words LINE and PUMP applied on the cables.
Before performing any installation or maintenance operation, disconnect the inverter from the electrical
mains and wait for at least 15 minutes before touching internal parts Ensure that the voltage and
frequency values on the inverter data plate correspond to those of the power mains.
