1.2 PRODUCT DESCRIPTION
The RAPIDA 2.0 inverter motor is an assembly of a three-phase asynchronous electric motor and an inverter
board, designed to allow the speed of the motor to be varied.
It is specifically fitted to the entire range of Doseuro "SR" series pumps.
Mechanical and electrical installation and commissioning of the inverter must only be carried out by
professional assemblers and installers who must have the general technical knowledge to install the product
correctly.
This documentation is a specific guide for:
−Assemblers or Installers who must electrically install the inverter motor in an installation or incorporate the
inverter motor into equipment or systems;
−Installers or technicians who must perform functional commissioning and calibration of the motor-inverter
already installed in the system.
This manual is also made available to the assembler to enable him to achieve the protection requirements of
Directive 2014/30/EC on ELECTROMAGNETIC COMPATIBILITY (EMC Directive) and to perform an installation
in accordance with CEI EN 60204-1:2018.
However, the manufacturer of the equipment, system or installation is responsible for the overall result of
electromagnetic compatibility according to the harmonised standards applicable to his product.
This information applies only to RAPIDA 2.0 inverter motors with single-phase voltage supply.
1.3 GENERAL CHARACTERISTICS
Inverter power supply:
from single-phase mains 230V/50-60 Hz. (on request from 110V/50-60 Hz. with appropriate power derating).

XMPI0MTIRPD2ST021 5/24 Ed. 2021
Power input:
on PG11 cable gland (PG11 cable gland is designed for cables with an outer diameter of 7 to 10 mm).
In order to comply with the IP degree of protection declared for the inverter, it is essential that the
cables passing through the cable glands have a circular cross-section.

power derating).
Inverter output frequency:
6 to 60 Hz in standard Rapida 2.0 configuration(
2
)
0 to 160 Hz(

The lower voltage limit ensures that the electronics do not switch off in the event of a low supply voltage. However,
under conditions of reduced supply voltage, the motor-inverter supplies less torque to its axis than the rated torque, so
the power output at rated speed may be reduced compared to the motor's rated speed. Under certain conditions of high
mechanical load and low supply voltage, the overcurrent protection may trip.
2
For severe and continuous use (more than 30 minutes) of the inverter at frequencies <=20 Hz, the use of servo-assisted
ventilation motors is absolutely recommended
3
The minimum operating frequency at which the motor reaches its rated torque depends on the characteristics of the
motor used in combination.

2. ELECTRICAL INSTALLATION OF THE INVERTER MOTOR IN THE SYSTEM
It is essential to read this chapter before proceeding with the electrical installation of the new or
replacement inverter or with re-installation following maintenance in the existing system.
Installation of the motor-inverter in the system may only be carried out by electrical installers,
manufacturers and professional operators in possession of the technical and professional
qualifications required by the laws in force. Installation is not permitted for private individuals or end
users.
With the exception of action with appropriate tools (3 mm blade screwdriver) on the connection
terminals (when the inverter is powered down), no operation is required or permitted on any part
of the inverter. In particular, it is not permitted to separate the electronic board from the base and
it is not permitted to tamper with, modify, replace or eliminate any of the electronic components
mounted on the inverter, failure to do so will invalidate the warranty.
After completing the wiring operations described in this chapter and before switching on the power
supply, it is essential to close the cover of the inverter to ensure the electrical safety of the
installation.

technical specification.

2.2. INVERTER MOTOR POWER SUPPLY
The power cable must be fed into the inverter through the PG11 cable gland on the side of the inverter box.
Use 2-pole sheathed cable plus earth, of suitable cross-section.
Shielding of the power cable is not required. However, for reasons of electrical safety and EMC protection,
correct earthing is absolutely essential. For this purpose, the PE terminal must be connected to the protective
conductor in the power supply cabinet.
For the power supply, the inverter is equipped with a spring-loaded terminal block (1) which guarantees
maximum mechanical tightness of the connection. The cable must have a circular cross-section and a diameter
suitable for the cable gland.
Press the orange terminals perpendicularly to the surface of the printed circuit board with a screwdriver with
a 2.5÷3 mm blade and insert the stripped wire for about 5 mm until resistance is encountered, then release
the terminal and check, with a slight pull on the wire, the tightness of the connection.
The protection fuse (2) is type 5x20 mm / 250 V - T10A (0.75 kW).

3. PROTECTION
The inverter is equipped as standard with a passive filtering stage, which allows it to be installed in accordance
with the requirements of EN61000-6-3 (Class A, industrial environment).
ATTENTION: The presence of the EMC filter on the inverter board may however cause the tripping
of incorrectly sized differential electrical protections when the inverter is powered up.
It is recommended to use earth leakage circuit breakers suitable for supplying loads equipped with
EMC filters.
Under no circumstances must the possible problem of tripping of the system's differential protection
be circumvented by removing the earth conductor connected to the PE terminal on the inverter
board, otherwise the installation will not be compliant from the point of view of electrical safety and
EMC protection.

4. UNINSTALLATION AND OPEN ENCLOSURE OPERATIONS
After switching off the motor-inverter, the upper cover of the inverter can be opened by unscrewing the four
screws. After that, the necessary uninstallation or maintenance operations are possible.
WARNING - RISK OF ELECTRIC SHOCK: Do not perform any type of direct operation on internal parts
or open the cover of the inverter unless it is powered down. If in doubt, disconnect the power supply
to the motor-inverter using the control devices in the electrical panel and wait at least 60 seconds
before opening the cover.
All installation, de-installation or maintenance operations must be carried out in strict compliance
with the current laws on "safety at work": the indications given here are of a general nature and
cannot take into account the specific nature of each installation.
It is therefore recommended that the safety requirements applicable to the context in which
operations take place are strictly observed. If there is a conflict between the possibility of carrying
out any of the operations described herein and the work safety requirements (laid down by law or
by the person in charge of the premises where the operations take place), compliance with the safety
requirements must undoubtedly prevail.
5. COMMISSIONING AND CALIBRATION
Powering up is only permitted after closing the inverter cover and tightening the four fastening
screws.
Pay particular attention to the correct positioning of the gasket between the cover and the base of
the box before tightening the screws.
Commissioning operations may only be carried out by adequately trained personnel or personnel
with the necessary professional skills and/or qualifications to work on live systems and mechanical
moving parts.
The instructions in this paragraph lead to the rotation of the motor shaft and the corresponding
operation of the pump. It is therefore essential to check that the motor-inverter is connected to the
mechanical transmission (lantern pump connection) and is able to turn without causing damage to
the transmission components or creating situations of danger to people or animals.
