WARNINGS
• Please read all parts of this manual carefully before installing and using the product.
• Check that the rating plate data is as required and matches the facilities.
• Only qualied personnel capable of making electrical connections in accordance with national regulations may carry out
installation and maintenance.
• TheVSP must only be used for the purpose and operation for which it was designed. Any other application and use should
be considered misuse and hazardous.
• In the event of a re at or near the installation site, do not use water jets, but use suitable extinguishers (powder, foam,
carbon dioxide).
• Install the equipment away from heat sources in a dry, covered place in accordance with the specied degree of protection
(IP).
• Only qualied technicians who are aware of the safety regulations in force may carry out any installation and/or mainte-
nance work.
• Use of non-original spare parts, tampering or improper use will void the product warranty.
• The manufacturer cannot be held liable for damage deriving from misuse of the product and is not responsible for damage
caused by maintenance or repairs carried out by unqualied people and/or using non-original spare parts.
DURING THE FIRST INSTALLATION PHASE AND IN THE EVENT OF MAINTENANCE, ensure that:
• THERE IS NO LIVEVOLTAGE on the electricity mains.
• The system IS NOT PRESSURISED
• The electrical power mains is equipped with safety devices and, in particular, a high sensitivity dierential switch (30
mA in class F and B) suitable to protect against fault currents, alternating type, unipolar button, continuous with high
frequency. Also check that the earthing complies with the regulations.
• Before removing the cover of the inverter or starting interventions on it, disconnect the system from the electrical mains
at least 5 minutes so that the capacitors have the time to discharge using the built-in discharge capacitors;
• Having carried out the electrical connection on the system, check the settings of the inverter.
• Do not remove the cover and/or disconnect theVSP power if the inverter is running.
ATTENTION: If out of services (display on in OFF with white background) VSP remains live; before any
intervention, it is compulsory to disconnect power from the unit.
EMERGENCY STOP
WhileVSP is running, you can make an emergency stop by disconnecting the power supply to the unit.
Ensure there is no VOLTAGE on the electricity mains. Make sure that the system is NOT PRESSURISED.

USE LIMITATIONS
• Maximum working pressure: 9 bar (130 p.s.i). (check with other models)
• Fluids permitted: clean and chemically non-aggressive liquid water; if impurities are found in the liquid, install a lter
upstream.
• Maximum ambient temperature: 40°C, with the possibility of changing the air.
• Minimum ambient temperature: -5°C
• Maximum temperature of the liquid: 55°C
• Minimum temperature of the liquid: 0°C
• Variation in voltage supply permitted ±10% compared to plate data.
• VSP is not suitable for pumping ammable liquids or working in environments with danger of explosion.
AUTO-LIMITATION FOR OVERLOAD
If the current detected by the inverter or the temperature of the inverter components exceeds the safety limits,VSP proceeds
with a progressive reduction in operating frequency until the values exceeding the limits have returned within them.

The VSP must be installed in compliance with the following conditions.
• In a ventilated room, protected from the weather and not exposed to sunlight.
• On a solid horizontal base with screws.

POSITIONING OF THE PRODUCT
• Fasten the unit to a horizontal surface with screws.
• If the pump must be installed outside where frost can occur, protect it to avoid freezing.
For correct operation of the VSP, installation is indispensable of an adequate expansion tank
.
• The expansion tank:
– Accumulates pressurised water to reduce pump start-up to a minimum.
– It is indispensable in the presence of small system leaks.
– It absorbs any excess pressure from the system.
–The minimum volume necessary, in litres (for membrane models) is approximately equal to 10% of the maximum ow
rate of the individual pump, expressed in l/min.
Example of standard application: Qmax = 80 l/min àV = 80 x 10% = 8 litres (rounded in excess to commercial size).
– Pre-load pressure (with system empty): 70% approx. of working pressure:
Example: Pset = 4 bar àPreload pressure = 4 x 70% = 2.8 bar.
• Correctly connect the pressure sensor supplied to the system (see next chapter).
PRESSURE SENSOR
A pressure sensor is a transducer that measures the pressure of a liquid or a gas, using an electric signal sent to a receiver in
analogue format. The pressure sensors are then also called pressure transducers.
The working principle is based on the physical deformation of the strain gauge in the transducer membrane: the electrical
resistance is proportional to the pressure applied, which is converted to an electric signal, the output is transmitted in cur-
rent that varies from 4 to 20 milliampere.
The pressure sensor should be positioned on the system as indicated in the gures on the previous page.

ELECTRICAL CONNECTION
Make sure that there is no voltage at the terminals of the line conductors before making the connec-
tions. Also ensure the electrical power supply mains is equipped with safety devices and in particular a
high sensitivity dierential switch (30 mA, in class F or B) and a ground compliant with standards.
• Check the electricity mains power supply voltage corresponds to the voltage indicated in the VSP inverter plate
and the motor, therefore connect the ground before every other connection.
• The voltage of the VSP power line can vary in a range between +/-10% of the plate power voltage.
• Check the rated current absorbed by theVSP unit is compatible with the plate data.
• The power line must be protected by a dierential circuit breaker switch, with the characteristics listed above.
• Secure the electrical cables in the corresponding terminals using a tool of suitable size to avoid damaging the clamping
screws. Take extra care when using an electric screwdriver.
• Do not use multicore cables containing both conductors connected to inductive power loads and signal conductors such
as sensors and digital inputs.
• Make connection cables as short as possible, and avoid forming them into a spiral shape as inductive eects could damage
the electronics.
• All wiring conductors must be suitably dimensioned to withstand the loads they supply.
• The electrical wiring between the electric pump and the inverter is carried out in the factory and therefore for operation
no operation is necessary.
CONNECTIONS DIAGRAM
To access the terminals of the connections board, remove the cover of the inverter.
Inside the inverter there is a POWER terminal board (1) and the INPUTS/OUTPUTS terminal board (2)
