1. Introduction
1.1. Purpose of the manual
The purpose of this manual is to provide users with detailed information on the installation, operation,
and maintenance of the product, paying particular attention to safety regulations.
WARNING
Read the manual carefully before installing and using the product.
WARNING
Failure to follow the instructions may result in damage to the product, the system in which
it is installed and, in the worst cases, damage to property or persons with even fatal con-
sequences.
NOTE
Keep the manual in a protected place near the installation and easily accessible for con-
sultation. A digital copy of this manual may be downloaded from the manufacturer's web-
site or by scanning the QR code on the product itself.
1.2. Product presentation
PSDrive is a device for the control and protection of pumping systems based on the variation of the
pump supply frequency. It may be applied to both new and old systems, thus ensuring:
• energy and economic savings
• simplified installation and lower system costs
• extension of system life
• improved reliability
PSDrive, when connected to any pump on the market, it manages its operation in order to keep a cer-
tain physical quantity constant (pressure, differential pressure, flow rate, temperature, etc.) as the con-
ditions of use change. In this manner, the pump, or the pump system, is operated only when and as
much as it is needed, thus avoiding unnecessary energy waste and extending its life. At the same time
the device is able to:
• protect the motor from overloads and dry running
• implement soft starts and soft stops to increase system life and reduce absorption peaks
• provide an indication of the current consumption and the supply voltage
• record the operating hours and, based on these, the errors and faults reported by the system
•
• connect to other devices to realize combined operation
Appropriate output filters, available upon request, allow for reducing the dangerous overvoltages that
are generated in very long cables and, therefore, make the device optimal also when controlling sub-
merged pumps.

or electrocution.
2.2. Qualified personnel
WARNING
The installation, use and maintenance of the product are strictly for qualified personnel
who have undergone appropriate training. Any use by unqualified personnel must be car-
ried out under the approval, responsibility, and close monitoring of the latter.
WARNING

WARNING
Failure to comply with the instructions may lead to loss of warranty.
WARNING
Keep out of the reach of children.
2.3. Safety warnings
WARNING
During installation and use of the product, comply with the general safety regulations,
working in a clean, dry environment, free of hazardous substances and using the appro-
priate accident prevention tools (gloves, helmet, goggles, shoes, and whatever else is
necessary).
WARNING
The product is suitable for installation in industrial environments. In case of installation in
a residential environment, it is recommended to adopt all the safety precautions required
by local regulations.
WARNING
The unsuitable use of the product, non-original spare parts or tampering with the hard-
ware and/or firmware of the product may lead to serious damage to property or persons
in addition to the loss of warranty. The manufacturer waives all liability due to the improp-
er use of its products.
WARNING
Before commissioning the product, ensure that the installation is safe and in accordance
with local regulations.
WARNING
Comply with the provisions to meet EMC requirements.
WARNING
Use cables of the appropriate type and cross-section according to the electrical charac-
teristics of the load, the ambient temperature and local regulations.

WARNING
Any insulation tests may only be performed in accordance with the manufacturer's in-
structions. Failure to do so may result in damage to the unit.
CAUTION
Electronic boards and components may be damaged by electrostatic discharge. We
therefore, recommend to don't touch the components.
CAUTION
Take care during installation and electrical connection that no foreign bodies enter into the
device.
DANGER
During the entire period in which the device is powered, regardless of whether it is operat-
ed or remains in stand-by (digital shutdown), high voltage is present inside the device and
at the input and output terminals.
DANGER
The device, previously in stand-by condition, may suddenly start up following the reset of
an alarm or changed system conditions. This may result in serious mechanical and elec-
trical danger to the operator who, upon seeing the device stopped, may have intervened
on it, on the load or on the system in which it is installed.
DANGER
Disconnect the device from the power supply, check that the load is completely stopped,
and wait at least 15 minutes before working on it or on the load applied to it.
DANGER
If the motor is of permanent magnet type, the device may be energised by the passive
rotation of the motor. In this case, it is recommended to disconnect both the power supply
and the load before working on the device itself.
DANGER
Ensure that the device is fully closed and all fixing screws are properly tightened before
supplying power. Do not remove the protective parts for any reason while the device is
powered on.

DANGER
It is recommended to install the appropriate protection devices upstream of the device,
such as a circuit breakers, fuses and a residual current device (RCD).
DANGER
Make sure that the device and the loads connected to it are properly grounded with the
appropriate connection terminals before commissioning.
Ensure that the grounding system is compliant and refer to local regulations for grounding
devices.
Each load must be fitted with its own earthing cable, the length of which must be as short
as possible. Do not make interconnected grounding connections.
Leakage currents may exceed 3.5 mA. It is recommended to use the reinforced ground
connection if necessary.
CAUTION
During device operation, some surfaces may reach high temperatures that may cause
burns upon contact with skin. Be very careful when touching the device!
Avoid contact with flammable products.
WARNING
Do not place any interrupting or switching devices between the inverter and the load. In-
terruption or switching during motor operation may cause serious damage to the device.
WARNING
Do not perform insulation tests on the load or power cable without first disconnecting
them from the device.
2.4. Acoustic emission
The device has a noise emission:
< 65 dB at a distance of 1 meter with the cooling fans at maximum speed.
2.5. Certifications
The product has the following certifications:
• CE
