1. DrivE-Tech Introduction
DrivE-Tech is a variable frequency drive designed to control and protect pumping systems by varying the output frequency to
the pump.
DrivE-Tech 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
DrivE-Tech, 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.
DrivE-Tech 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 DrivE-Tech units for combined operation
Through the use of inductive filters (optional) DrivE-Tech eliminates dangerous surges that are induced in long cables, making
DrivE-Tech 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 DrivE-Tech
itself (including visual inspection) and/or on the connected load.
Disconnect DrivE-Tech 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.
DrivE-Tech and pumping system must be grounded properly before operation.
For the entire period DrivE-Tech is powered, high voltage is present on the output
terminals of the inverter whether or not the pump is running.
Tightening all 4 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 DrivE-Tech 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.

4.1 Protections
The protections required upstream each DrivE-Techs depends on the type of installation, and local regulations. We
recommend to use overload protection with the characteristic curve of type C and type B circuit breaker, sensitive to both AC
and DC current.
4.2 Electromagnetic compliance
To ensure electromagnetic compatibility (EMC) of the system, it is necessary to apply the following measures:
Always connect the device to ground
Use shielded signal cables by placing the screen at one end.
Use motor cable as short as possible (<1 m / <3 ft). For longer lengths, it is recommended to use shielded cables
connecting the screen at both ends.
Separate signal, motor, and power supply cables.
Note: To enable the restoration of the display screen when there are electromagnetic interference, DrivE-Tech
periodically provides some fast "refresh" of the display.
4.3 Installation with long motor cables
With long motor cables it’s recommended to decrease the
commutation frequency from 10 kHz (default) to 2.5 kHz
(advanced parameters). This reduces the probability of
voltage spikes in the motor windings which may damage the
insulation.
To prevent dangerous overheating of dv / dt and sinusoidal
filters it is recommended to set the correct PWM value in
relation to the cable length.
For motor cable lengths up to 50 meters it’s recommended
to place between DrivE-Tech and motor a dv / dt reactance,
available on request.
For motor cable lengths greater than 50 meters it’s
recommended to place between DrivE-Tech and motor a
sinusoidal filter, available on request.

5. DrivE-Tech installation
DrivE-Tech can be installed directly on the fan cover of the motor or mounted on the wall.
Motor mounting kit
In this application DrivE-Tech is cooled by the motor fan. Motor kit (available upon request) allows a solid coupling of the two
units and it is composed of:
DrivE-Tech 015,030,022,040
DrivE-Tech 055,075,110,150
n.°4 rods
n.°4 M5 nuts
n.° 4 hooks
n.° 1 cooling ring
n.° 4 M5 screws.
n.° 4 clamps
n.° 4 clips to add if necessary
n.°1 centre pin
Use the cooling ring for best cooling of DrivE-Tech during
operation. Warning: when using the cooling ring, the
cooling air of the motor is slightly warmer than without
the DrivE-Tech; if the resulting motor temperature
exceeds the indicated maximum allowable value, remove
the cooling ring, leaving the DrivE-Tech to be cooled by
itself.
