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 mainte-
nance of the product, with special regard 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 consequences.
NOTE
Store the manual in a protected and easily accessible place next to the installation location for
possible consultation. A digital copy of this manual can be downloaded from the manufacturer's
website or via the QR code shown on the product itself.
The complete installation, use and maintenance manual of the product, constantly updated in its contents, can be
downloaded by scanning the QR code shown in the product with the smartphone camera and following the relative
link.
1.2. Product overview
MIDAis a device for the control and protection of pumping systems based on the variation of the pump power
supply frequency. It can be applied to both new and old systems ensuring:
• energy and economic savings
• simplified installation and lower system costs
• extended life of the system
• improved reliability
MIDA, when connected to any pump on the market, it manages its operation in order to keep a certain physical
quantity constant (pressure, differential pressure, flow rate, temperature, etc.) as the conditions of use change.
In this manner, the pump, or the pump system, is operated only when, and to the extent that, it is needed, thus
avoiding unnecessary energy waste and extending its life. At the same time the device can:
• protect the motor from overloads and dry runs
• 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 obtain combined operation
Appropriate output filters, available upon request, allow reducing the dangerous overvoltages that are generated in
very long cables and, therefore, make the device ideal also for controlling submerged pumps.

WARNING
The unsuitable use of the product, non-original spare parts or tampering with the hardware 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 improper 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 characteristics of the
load, the ambient temperature and local regulations.
WARNING
Any insulation tests may only be performed in accordance with the manufacturer's instructions.
Failure to do so may result in damage to the unit.
CAUTION
Electronic boards and components may be damaged by electrostatic discharge. We therefore, rec-
ommend 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 operated 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 electrical 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 intervening on it or on the load applied to it.
DANGER
If the motor is of the permanent magnet type, the device may be energized by the passive rotation of
the motor. In this case, both the power supply and the load should be disconnected 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 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. Interruption 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 an acoustic emission:
<65 dB at a distance of 1 meter with cooling fans at maximum speed.
2.5. Certifications
The product has the following certifications:
• CE
3. Maintenance
