OPERATING INSTRUCTIONS

1. Introduction
We strongly suggest that the operator carefully
reads and follows the information contained in
this instruction manual for the frequency
converter.
Symbol used:
This symbol indicates high voltage
hazard. It draws attention to components
or procedures that could represent a
potential danger to the health and welfare
of the operator.
This symbol is used to draw the operator's
attention to situations of potential danger
for people or for operations that could
cause damage to the product.
2. Special warnings regarding
the frequency converter
We strongly suggest that the operator
carefully reads and follows the information
contained in this instruction manual for the
frequency converter.
The FREQUENCY CONVERTER should
NEVER be opened or tampered with
and guards that come with it should
never be removed.
The frequency converter must be
installed, adjusted and maintained by
qualified personnel who understand the
risks involved.
The frequency converter must be fitted
with voltage surge and overload
protection devices, in accordance with the
prevailing safety standards.
The connection of the alarms can
distribute power even when the frequency
converter is turned off. Ensure that there
is no residual voltage on the terminals of
the alarms.
All the power terminals and other
terminals must be inaccessible after
installation is completed.
The maximum output frequency must not
exceed the design frequency of the pump
being controlled. Operating at a frequency
higher than the allowable frequency can
cause higher current absorption and
damage to the device.
If it is necessary to remove the frequency
converter, remove only the covers
required in order to disconnect the
electrical cables. Take care not to damage
the electronic cards.
Failure to comply with the safety
regulations not only causes risk to
personal safety and damage to the
equipment, but also invalidates every right
to assistance under warranty.
Electro-magnetic compatibility.
The frequency converter is constructed in
compliance with European standard 2004/108CE.
Responsibility:
The manufacturer is not liable for malfunctioning if
the product has not correctly been installed,
damaged, modified, and/or run outside the
recommended work range or not in accordance
with other indications given in this manual.
The Manufacturer declines all responsibility for
possible errors in this instructions manual, if due to
misprint or error in copying.
The Manufacturer reserves the right to make any
modifications to products that it may consider
necessary or useful, without affecting the essential
characteristics.
The responsibility of the manufacturer is limited to
the product and excludes costs or greater damage
caused by incorrect installation.

5.3.1. System icons
AUTO MODE
The system is operating in auto mode.
MANUAL MODE
The system is operating in manual mode.
SET-UP MODE ACTIVATED
It shows that the set-up menu is activated.
When a icon is blinking you are modifying
a parameter. You can confirm with
enter.
ALARM
It indicates that there is a fault on the
system, the error number appears on the
display area. When you are on the set-up
mode the alarm icon will not appear
SENSOR STATE

with the pressure transducer; if it is blinking
there is a fault on the pressure transducer.
PUMP STATE
It indicates if the pump is running or in
stand-by state.
CASCADE MODE
It indicates that the cascade control mode
is working. The 2 upper symbols show if
the pump is running or if the pump is in
stand-by. The lower symbol informs if the
pump is the master (lighted icon) or slave
(blinking icon).

5.3.3. Operating icons
Constant pressure mode
The system keeps the pressure constant
when the quantity of water requested by
the user changes.
Fixed speed mode
The system works at a fixed speed that
user can choose according to need.
5.4. Submersible pumps
applications or long cables
To operate a submerged pump (or surface
pump),where the distance from the inverter is
more than 10 m, see paragraph 18.
Submersible motor must operate with a
frequency between 30 Hz (minimum
operating frequency) and 50 Hz
(maximum frequency) for 50 Hz motors,
and between 30 and 60 Hz for 60 Hz
motors.
The running up time from 0 to 30 Hz and
the running down time from 30 Hz and 0,
must be as short as possible, according to
the motor power to operate.
6. Installation
For easy assembling and disassembling of the
frequency converter we recommend to respect the
minimum distances as show in figure herebelow.
In case of reduced distances connect the
frequency converter with the proper unions (see
paragraph 16.3.).
Do not install the control panel in places exposed
to direct sunlight or near sources of heat.
Fasten the heatsink (a) to the pipe by means of the
pipe housings (b1-b2) and the screws (c) in
equipment.

The pressure transducer (d) must be installed on the
system. We always advise the installation of a small
accumulator (e) (8 ltrs minimum) on the pump delivery
side.
7. Electrical connection
Electrical connection must be carried out
by a qualified electrician in accordance
with local regulations.
Follow all safety standards.
The unit must be properly earthed
(grounded).
Follow the instructions in the wiring
diagram attached.
Once the electrical connection has been
completed, remove any pieces of wire,
sheath, washers or any other foreign bodies
that may be found inside the frequency
converter.
For the electrical connections on both the
terminal board and the motor use cable with
a maximum section of 2,5mm
2
. We also
advise the use of insulated pin terminals.
Bad connections may damage the electronic
circuit.
7.1. Power supply line
Power supply line must comply with the provisions
under paragraph 4.
If a differential protection is necessary,
install a type A differential switch,
protected against untimely activation and
with threshold of intervention of 30 mA.
Electrical connection
7.2. Motor connection
The power supply line of the electrical motor must
be connected directly to the output terminal of the
inverter.
To comply with the standards of
electromagnetic compatibility, use a
shielded three-pole cable (for MM models)
or a shielded four-pole cable (for MT
models) with external protection sheath.
The power supply line of the motor must never run
parallel to the power line of the electrical panel.

The EASYMAT frequency converters are
prearranged for use in pressure boosting sets with
up to 3 pumps in the following versions:
- Pressure boosting sets with 2 variable speed
pumps
- Pressure boosting sets with 3 variable speed
pumps
- Pressure boosting sets with 1 variable speed
pump and 1 fixed speed pump (single-phase)
7.4.1.
Cascade mode
installation
Connect the frequency converters on the delivery
pipes of the pumps, the installation must comply
with the provisions under paragraph 6.
Connect the pressure transducer to the delivery
manifold of the pressure boosting sets.
It is advised to install the pressure
transducers on the same point of the
delivery manifold and complete the
installation with a pressure gauge.
7.4.2.
Cascade mode
electrical
connection
Connect the supply cables to the motors and to the
power supply following the instructions under
paragraph 7. The power supply must comply the
provisions of the paragraph 4-5.
The connection with the power supply
must be made with interpositions of
magnetothermal bipolar switches (one for
each frequency converter).
For these frequency converters an earth leakage
circuit breaker or ground fault circuit interrupter,
type B.
This circuit breaker or interrupter must be marked
with the following symbols:
7.4.3. Cascade connection with
variable speed pumps
Electrical connection with 2 pumps
By means a proper cable make the connection of the
clamps number 4-5-6 of both frequency converters.
Electrical connection with 3 pumps
By means a proper cable make the connection of the
clamps number 4-5-6 of each frequency converters.
User must provide a jumper connection
into 1 frequency converter as shown in the
picture.
Check the correct connection sequence and
check that terminals of each cable are
connected on the clamp with same number.
To comply with the standards of
electromagnetic compatibility, for cable
length greater than 1 meter, it is
recommend the use of a shielded cable
with protection sheath connected on the
ground of both frequency converters.
7.4.4. Cascade connection with
1 variable speed pump
and 1 fixed speed pump
Connect the clamps 10-11 with a contactor with
