7. INSTALLATION AND ASSEMBLY
Before installing the frequency inverter, carefully read the whole of this manual and consult the
safety regulations in force in the country in which it will be used.
The installation must be carried out by a qualified technician.
a) Installation of the frequency converter:
- It must be installed in a well ventilated area, protected from damp and direct exposure to the sun and rain.
- Before making the electrical connections, ensure the cable used to provide power to the frequency converter is
not live.
- Carefully verify the electrical data indicated in the specifications plate of the frequency converter before connecting
the electric current.
- The electric power cables to the frequency converter, and from the frequency converter to the pump, must be of the
correct size for the nominal consumption of the motor and the length of cable required, according to the regulations
in force in the country in question. A table with the maximum recommended lengths according to the cross-section
of the electrical cable can be found below.
- Each interface cable lenght should be shorter tan 3 meters.
- Use the appropriate cable glands to attach the cable.
- Also ensure that the grid has electrical protection; a high-sensitivity differential switch (30 mA, class A for
domestic applications, Class B for industrial applications) is particularly recommended.
The type B should be installed for all the residual current-operated protective or monitoring from an
inverter up to the supply voltage.
- In addition to the differential switch, it is advisable to install magnetothermal protection and a voltage disconnect
switch to control the power supply to each frequency converter individually.
Ground must be connected properly. If the ground is not connected, the electric shock or fire might be
happened.
b) Installation of pressure units with a frequency converter:
- The multiple pump unit must always consist of pumps that are the same and that, therefore, have the same power
and hydraulic performance. Failure to comply with this point can cause the pump system to malfunction.
- For the frequency converter to work, it is essential to use a pressure transducer (4-20 mA).

7
EN
EN
- The location of the pressure transducer must always be as close as possible to the pump unit, as close as possible
to the membrane expander, and always after the general retention valve of the pump unit It is essential to install
a general cut-off valve for the pump unit, after the physical location of the pressure transducer.
- If there is more than one pressure transducer in a multiple pump unit (more than one frequency converter with
a pressure transducer connected), the network of interconnected frequency converters will decide automatically,
and with prior reliability tests of the readings of the existing transducers, which is the transducer that will be used
as the general pressure sensor for the whole group.
- If the designated transducer functions erroneously, the set of frequency converters will decide to automatically
change the principal transducer for another that provides more precise readings. The rest of the transducers will
remain on standby ready to be used when required.
c) Installation on a motor:
- Replace the cover of the motor terminal box with the motor support adapter (parts 5 and 11a) provided.
- Break the 3 holes of the metal radiator of the power circuit (part 4) with a screwdriver. The 3 holes are visible
on the inside of the radiator (add the image).
- Screw the metal radiator to the motor support adapter with the help of the 2 screws provided for this purpose
(parts 9 and 11b).
-Tighten the appropriate cable glands to guarantee the declared protection rating (part 10).
- Carry out the electrical connections between the power circuit and the motor using the electric cables supplied
(item 6).
- Connect the power circuit to the cover + control circuit (part 1) using the flat cable.
- Screw the assembly together (part 13).
d) Installation on a wall bracket:
WARNING: For installation on the wall, point 2 of the previous section regarding installation on a motor should
not be carried out, since the 3 holes in the metal radiator would not ensure the adequate protection rating.
- Fix the wall bracket to the wall through the 3 rear holes of the wall bracket (part 7).
- Place the fan at the base of the wall bracket, ensuring upwards airflow (part 8).
- Place the inverter assembly inside the wall bracket, ensuring that the 2 ends of the metal radiator are inside
the wall bracket.
- Fix the inverter to the wall bracket using the 2 side screws drilled into the metal radiator (part 14).

12. START-UP WIZARD
The first time you connect the voltage to your unit, a start-up wizard will run in which you can configure the basic
parameters to be able to start up the pump unit. This wizard only runs on one of the units regardless of the total
that are connected.
While using this wizard the red LED will blink indicating that this process is under way.

11. OPERATION MODE
The operation mode of the frequency converter will continuously seek to minimise the electricity demand, at the
same time guaranteeing minimum wear to the pumps.
a) Single pump unit:
By the direct reading of the pressure transducer, the variable speed drive is responsible for managing the rotation
speed of the electric motor of the pump, guaranteeing the mains pressure remains fixed and unaltered, regardless
of the instantaneous demand for flow required. When the demand for flow is at its greatest, the pressure of
the water network decreases. In this point the pressure transducer, which continuously informs the frequency
converter of the current pressure, causes the frequency converter to make the electric motor rotate more quickly,
guaranteeing the established working pressure. In contrast, when the demand for flow decreases, the frequency
converter makes the electric motor rotate more slowly so the pressure of the water network remains unaffected.
b) Unit with several pumps (Multi frequency converter):
When there is a network of two or more frequency converters connected together, the system decides in an alternate
and orderly manner which pump must start up first, when there is demand for flow. Once this pump starts to rotate,
if it stops because there is no more demand for flow, the system will start up a different pump the next time it starts
up, rotating all the pumps that comprise the network of frequency converters so that all the pumps in the frequency
converter network are started up the same number of times.
If a pump is running and reaches maximum rotational speed and the network pressure does not reach the
established working pressure, the system will decide whether to start up one more pump, to support the first one
or however many are running at that time. At that time the network of frequency converters will calculate the
rotational speed of the motors that guarantee the minimum electricity demand at the same time as maintaining
the working pressure.
Similarly, and with this same premise of maximum energy savings, the system will continually calculate when it
can disconnect each pump that is running at any time.

The system automatically indicates the number of frequency converters
(x) that are connected to your network. It is an indicative parameter
and cannot be modified.
With F1 you can repeat the automatic search if the value shown “x” is
different from the real value.
If you perform various searches and the value still does not coincide,
there is probably a connection error in the network of frequency
converters.
Before carrying out this point, you must use the graphic sign on the
pump motor to check its rotation direction, as it may be clockwise or
anti-clockwise depending on the pump model.
In this point you can see how the motor makes a sequence of slow
turns so you can easily see whether the rotation direction is correct. It
performs 6 rotation tests and stops the motor.
F1 restarts the rotation test.
If the rotation direction is not correct, select NO with the arrows and
restart the test by pressing F1 to verify that the rotation direction has
been changed successfully.
Once you have verified that the rotation direction is correct, select YES
and then accept it with F2.
Use the arrow keys to increase or decrease the value that is blinking
and use F2 to change to the next value. The sequence of values is:
DAY →MONTH →YEAR →HOUR →MINUTES
The lower left part of the display indicates the day of the week
calculated automatically according to the date entered.
When you modify the last value (minutes) you can accept the changes
by pressing F2.
NOTE: At any point of the date you can go back to the previous value
by pressing F1.

We must follow the instructions indicated on the screen exactly.
• Open propulsion: You must open the general propulsion of the
system to cause consumption of flow.
• Click on OK: Once the propulsion is fully open, accept it using F2.
Once you have pressed F2, the pump will start up
In this point you must enter the nominal consumption of the motor,
increasing or decrease the value using the arrow keys and validating
with F2.
NOTE: The nominal consumption is indicated on the specifications
plate of the motor. You must choose the correct value, for example if
you connect a frequency converter MT 2200 select the value 230 V and
for TT 4000 400 V.
F2
Use the arrow keys to enter the maximum range for the pressure of
the transducer connected.
This value is indicated on the specifications plate of the pressure
transducer, and must always be between 4 and 20 mA.
Validate this with F2.
F2
Use the arrow keys to enter the pressure at which you want the unit
to work.
You must take great care that this value is always within the working
curve of the pump, and always try to avoid the extremes of the curve,
in other words with flows near 0 or very low pressures.
Validate this with F2.
F2
Once you have reached this point, the frequency converter will
program itself to know when it no longer has any demand for flow and
should stop. To do this it will ask for help to understand the features
of the installation to which it is connected.

START-UP WIZARD IN SYSTEMS WITH TWO OR MORE PUMPS
In systems with two or more pumps, the start-up wizard will run in the unit that has the transducer connected,
and only that unit will indicate the first screen of the wizard. if there is more than one pump with a transducer
connected, the system will decide automatically which unit of those that have a transducer will be used to run the
wizard.
Once the wizard has finished in the unit selected, the other units on the network will be fully programmed with
the same data. It will only remain to run the rotation test of its wizard and the slave pumps will have the red
warning light on and an indication on the screen of the rotation direction test. Once their rotation tests have been
performed, it will go directly to the main screen and the assembly will be fully programmed.
F2
F2F1
At this point you must close the propulsion gradually (using a
minimum of 5-7 sec) until the flow consumption is zero. At this
moment the pressure of the installation must be pressure entered
previously in the wizard.
Once the propulsion has been closed and the working pressure
established, press F2 to accept.
The option “Accept” will only appear if we reach the work pressure
that we have indicated. In the case of not reaching the set pressure
without water consumption, the “Accept” option will not be displayed.
The stop frequency calculated is indicated, this is: for the working
pressure indicated, when the pump drops below this frequency it does
not generate any flow so the motor then stops. Press F1 to return to
the initial stop frequency search screen. Accept by pressing F2.
It shows a text for a few seconds indicating that the wizard has finished
successfully before showing the main screen.
NOTE: All the data entered or calculated in the wizard can be modified later through the unit menu.
• Wait 10 seconds: It displays a ten-second countdown after which the
next step to take will be indicated.
This countdown will not start if the indicated pressure is above what
we have set in the set pressure. If once the countdown starts the
pressure increases too much, the counter will show the 10 seconds
again until the pressure does not decrease.

Alarm (NC): The relay opens before an alarm.
Running: The relay is energised when the unit is
running.
External stop: The relay is energised when there
is an external stop. (For this condition we must have
programmed a digital input as “·Start/Stop”).
Dry running: The relay is energised if the converter
detects dry running.
Clock (NO): The relay closes depending on the time
data programmed in parameters 5.16 to 5.21.

We can use the digital input as a system start-stop by
closing the input circuit, or by opening it if we select
the INV option.
It can also be used as a second set pressure in the same
way. Closing the circuit of the programmed input, the
system will ignore the second set pressure (parameter
5.05). The operation described is the reverse if we choo-
se the INV option.
“Flow Sensor NC” can be selected when a flow sensor
is available, which will stop the pump when the contact
is opened.
Selecting “Unused” will not affect the system.

The RUN LED blinks. The frequency converter is in the process
of stopping the pump.
WARNING REASON EXPLANATION / SOLUTION
14. WARNING MANAGEMENT
One of the main principles of the frequency converter is to try to avoid the failure of the hydraulic supply. To do
this, the frequency converter has systems that, in the event any reading for the pressure/consumption of the motor
is outside of the established limits, it may partially lose its ability to try to avoid the frequency converter locking
and, therefore, avoid the failure of the hydraulic supply.
A clear example is an excessive consumption of the electric motor. In this specific scenario, the frequency converter
will limit the rotational speed of the motor to avoid its deterioration, maintaining the consumption of the motor
equal to the nominal consumption, thus the hydraulic installation will continue to receive flow from the pump, not
at the working pressure established, but at a somewhat lower pressure.
A table specifying the current state of the system operation, according to visual warnings that are shown using both
the LEDS and the main screen can be found below:
