1. Introduction
VASCO – VAriable Speed COntroller is a variable frequency drive designed to control and protect pumping systems by varying
the output frequency to the pump. It can be applied to both new and existing pumping systems, and provides:

energy and cost savings

simplified installation and an overall lower pumping system cost

longer life of the pumping system and relevant components

improved reliability
VASCO – VAriable Speed COntroller, when connected to any pump, manages the system operation to maintain a certain
constant physical quantity (pressure, differential pressure, flow, temperature, etc.) regardless of the conditions of use. The
pump is operated only when needed thus avoiding unnecessary energy consumption.
At the same time is able to:

protect the motor from overload and dry running

implement soft start and soft stop to increase the system life and reduce current peaks

provide an indication of current consumption, voltage, and power

maintain a record of run time and display any errors and/or failures reported by the system

control up to two additional pumps at a constant speed (Direct On Line)

connect to other units for combined operation
The use of inductive filters (optional) eliminates dangerous surges that are induced in long cables, making the inverter
suitable for control of submersible pumps.
2. Safety Instructions
The manufacturer strongly suggests carefully reading this operation manual before using and installing its products
Any operation (installation, maintenance and repair) must be carried out by trained, skilled, and qualified personnel.
Failure to observe and follow the instructions in this manual may result in dangerous and potentially lethal electric shock.
Pay attention to all standard safety and accident prevention regulations.
The device must be connected to main power supply via a switch to ensure the
complete disconnection from the network before any operation on the unit itself
(including visual inspection) and/or on the connected load.
Disconnect the device from the main power supply before commencing any
work. Do not remove, for any reason, the cover and the cable plate without
having first disconnected the device from the main power supply and having
waited at least 5 minutes.
The inverter and the pumping system must be grounded properly before
operation. For the entire period the unit is powered, high voltage is present on
the output terminals of the inverter whether or not the pump is running.
Tightening all screws on the cover with washers is recommended before
powering the device. Otherwise, there may be a failure to connect the cover to
ground, creating the risk of electric shock or even death.
Avoid any shock or significant impact during transport. Check the product immediately upon delivery and check for damage
and/or missing parts. If either occurs, immediately notify the supplier. Damages due to transport, incorrect installation, or
improper use of the device will null and void the warranty. Tampering or disassembly of any component will automatically
void the warranty.
The manufacturer cannot be held responsible for any damages to people and/or property due to improper use of its
products.
Devices marked with this symbol cannot be disposed of in household waste but
must be disposed of at appropriate waste drop-off centres. It is recommended
to contact the Waste Electrical and Electronic Equipment drop-off centres
(WEEE) in the area. If not disposed of properly, the product can have potential
harmful effects on the environment and on human health due to certain
substances present within. Illegal or incorrect disposal of the product is subject
to serious administrative and/or criminal penalties.
