4.1 Wall Inverter fixing in vertical position
Install the product in place away from frost and weather conditions,
mounting the unit on a wall in a vertical position only, leaving at least
200mm of space above and below the same so as to ensure sufficient
cooling of the heat sink on the back of the inverter. The wall may also
be of metal type as long as it is not a heat source and be not directly
exposed to the sun.
For wall mounting the inverter using the N° 4 holes 7mm diameter
arranged in the pattern of holes in Figure 2.
4.2 Electric and hydraulic connections
Connect the
input voltage supply plug (schuko standard) on the line (N°1,
fig.3)
For the feedback pressure control you need to connect to the
pump outlet, the pressure transducer supplied (No. 2 fig 3), ¼
"M, coming from the central of the inverter.
Connect the motor supply cable (N°3 of fig.3) to the
asynchronous motor of the pump.

4.2.1 Connecting the pressure transducer to New waterworks system
•Connect the pressure transducer in the hole of the filling cap ¼ "F
of the pump provided to the output pressure (depending on the type
of pump);
•On the delivery of a multistage pump, assembled with a T-fitting is possible to
mount the pressure transducer in place of the pressure gauge.
Be aware that: in multi-stage pumps with the hole filling near aspiration it is not
possible to mount the pressure transducer at that hole because it will not do the
correct output pressure.
•Use ¼” F hole for the pressure gauge, which can be – in case – removed
for connecting the pressure transducer;
•Use any other ¼ "F hole on the pump hydraulics connections, possibly
removing the cap (such as a hole for venting air);

4.2.2 Connecting the pressure transducer to Old waterworks system
•Pump comes with PRESSURE-SWITCH with tank or with galvanized steel
tank: mount the pressure transducer in place at the pressure switch, using
reduction to ¼ "M. In case you need to maintain the switch for maximum
pressure additional security, connect the N.C. output of the switch to
ENABLE and 0V contacts (poles 2 and 5 of J5 electronic board, fig. 14 and
15)
•Pump comes with flow switch device: replace the flow switch with a T-fitting
flow and in the central hole screwing the pressure transducer. This allows you
to eliminate the problem of any blocking of the valve flow and to eliminate
pressure drop, does mean eliminate all the problems inherent the flow switch
systems.
•It is possible to use a valve or other type of output provided at the delivery of the pump.
In case of installation of the check valve on the outlet of the pump, place the pressure transducer after the valve.
4.2.3 Membrane Tank
For an optimal pressure control is recommended to mount a small diaphragm tank
(12L are usually good for a pump up to 2Hp).
For a perfect operation of the control of pressure, make sure that the tank is capable
of withstanding the pressure and set the correct pressure to pre-load before
connecting it to (normally 0.5-1 Bar less than the working pressure) .
4.3 Inverter – Pump connection
Do connect the cable of the Inverter (No. 3 of fig. 3nd) to the power plug of the pump, if the pump incorporates the
capacitor.
To connect a single phase pump
without capacitor incorporates to
IMMP1.1W, IMMP1.5W, IMMP1.5W-

The single-phase input / three-phase output inverter
IMTP1.5W, IMTP1.5W-BC must be installed on
asynchronous three-phase motor with 230Vac 50/60 Hz
voltage supply. Phases must be configured to delta mode if
the motor is 230V ∆/ 400V λ(most common case, as in
Figure 12).
Figure 12 – Delta motor phases connection
The three-phase input / three-phase output inverter
ITTP1.5W-BC must be installed on asynchronous three-
phase motor with 400 Vac 50/60 Hz voltage supply. The
phases must be connected in star mode if the motor is 230V
∆/ 400 V λ(most common case, as in Fig 13).
Figure 13 – Star motor phases connection
The unit is equipped with output over-current protection; it is not necessary to install any additional safety device
between the inverter and the pump in order to protect the motor in case of failure.
Make sure the pump is in accordance with the operating conditions listed in Chapter 2 of this handbook.
In case of submersed motor pump with a cable length more than 20 meters be sure that the motor-pump is designed
to works with inverter (may have a good phase-phase electrical insulation and not conductive rolling bearings)
otherwise you need to use the specific output filter (optional – ask our sales service) connecting it between the inverter
output and the motor pump voltage supply cable.
WARNING: : it is not possible to use an additional starting capacitor with circuit breaker; if the motor already
has this type of capacitor wired, it must be disconnected, and the pump will start normally through the
inverter and only the capacitor operating in permanent mode.
4.4 Inverter electric connection to line
The line voltage supply must match with the Inverter limits, described on chapter 3 – WORKING
CONDITIONS. Do ensure proper protection from general electrical short circuit on the line.
The plant to which the inverter is connected must be conforms to safety regulations in use:
•Differential automatic switch with I∆n = 30mA: the correct switch is the type A or B, able to recognize leakage
currents with pulse components and direct components, immune to the electromagnetic interferences typical
of the inverters and cut-wave electronic rectifiers.
• Ground connection with total resistance less than 100 Ω
• If required by local electrical regulations in force, the installation of a differential circuit breaker, make sure it
is of a type suitable for installation (see table below).

Before reopening of the inverter box to possible change cable or other components, after
functioning, remove voltage and wait at least two minutes, then you can open the box (danger:
contact with electric high voltage parts).
The unit is equipped with all those technical arrangements required to ensure a good functioning
under normal situations installation.
The control system has a entry-filter, also have a current overload protection which guarantees absolute protection
when the Inverter is combined with motors that not exceed the maximum power.
For EMC is good that the power wires of control panel and motor power wires (when the motor are separated
from the inverter) are shielded type (or armoured) with individual conductors of appropriate section (current density
<= 5 A/mm2). These cables must be the minimum length necessary. The screen conductor must be connected
to the ground by both sides. On motor use the metal case for connection to the ground of the screen.
To avoid loops that can create mass disturbances radiated (antenna effect), the motor operated by the frequency
converter must be connected on the ground individually, always with a low-impedance using the metallic box of
the machine.
The wires from power supply to frequency converter and wires from frequency converter – motor (if the motor is
separated to the Inverter) must be spaced as much as possible, not to create loops, not make them run parallel
less than 50 cm.
Don’t observe these conditions could cancel completely or partially the effect of the filter integrated.
4.5 Access to the electronic board
In case is necessary to change damaged cables, pressure transducer or to add the float switch contact, you need
to open the Inverter case.
The operations of a component for the inverter must be performed only by experienced personnel
qualified by the manufacturer, using only original spare parts supplied by the manufacturer.
Any action with open box of the Inverter must be made after at least 2 minutes after open line
with appropriate switch or the physical separation from the power supply cable;
In case of failure to one of the cables or the pressure transducer, for the replacement of that
should be opened by unscrewing the inverter cover the N° 12 screws in the back on the heat
sink. For the extraction of a cable, unscrew the three screws that close the cable triangular plate. Remember to
always replace the O-ring seal on the cable under the plate. To connect the cables in the appropriate terminals
follow the pattern of connections in the electronic board below (fig. 14-15):
•Single-phase Inverter power supply cable for IMMP1.1W, IMMP1.5W, IMMP1.5W-BC, IMTP1.5W,
IMTP1.5W-BC: contact 220Vac + GND (J4, fig.14);
•Three-phase Inverter power supply cable for ITTP1.5W-BC: contact L1, L2, L3 + GND (J7, fig. 15);
•Single-phase Motor power supply cable on IMMP1.1W-1.5W-1.5W-BC: contact S, T (J3, fig.14);
•Three-phase Motor power supply cable on IMTP1.5W – 1.5W-BC: contact R, S,T (J3, fig.14);
•Three-phase Motor power supply cable on ITTP1.5W-BC: contact U, V,W (J9, fig.15);
•Pressure transducer with 4-20 mA output: contact +15V, S (J5, fig.14 and 15);
•Float switch: contact ENABLE, 0V (J5, fig.14 and 15);
•Motor ON output signal: Contact MOTOR ON, 0V (J5, fig.14 and 15 - closed when the motor is ON, max.
30V, 3mA)
4.6 Connecting the float contact or other NC contact
To connect an enable Normally Closed contact use the poles 2 (Enable) and 5 (common) of J5 (fig. 14, 15). When
the contact open, the Inverter stop the pump; when the contact close, the pump may re-start at previous working
condition.
For the connection of the float switch contact, you need to change the three poles cable of the sensor with a four
poles cable, passing on the same central exit of the transducer cable.
The new connections of pressure transducer and float switch contact must be done out of the
Inverter box, protecting them to humidity, water and dust. Do not practice others holes to the
Inverter case to avoid damages or decrease of the protection and insulation grade and
interruption in anticipation of the guarantee.

Table 4: Led description
NOTE: after connecting the Inverter plug on voltage supply, the panel show on the circular led bar a sequence of three
consecutive flash followed by the number of the software version.
5.1 Programming
A) Make sure the pump is charged (full of water); in case the pump is not charged provide it a direct voltage
supply (without Inverter) until the complete filling of water, then re-connect the pump to the Inverter;
B) In case the pressure of the system is more than 3 BAR open the delivery to reduce it under this value, then
completely close the delivery or all of the valves on the output of the pump (very important condition);
C) Press START to start the self-regulation check. Wait roughly one minute for a completed cycle, and once
the flashing Led bar is completed indicate the data saving and the pump stop for null flow condition
(Minimum flow);
D) At this point the Inverter is running; It is now possible to open the delivery of the pump and work; the
reference default pressure, modifiable, is 3 BAR;
E) If necessary, adjust the working pressure acting on keys and on panel; during the reference
pressure setting the led bar is flashing up to one second of data saving; the measured pressure is indicated
by fixed led bar;
F) For a correct over-current motor-pump protection set the maximum current with F2 on advanced functions
(chap. 5.2) reading the nominal motor data value.
The inverters generally comes to the user with the constructor data (default); if for any reason i.e. (such as
inverters had been previously tested and configured for another pump) the inverter is pre-regulated, in order to
RESET before self-regulation test, is necessary to perform this following:

11 IMMP1.1W – IMMP1.5W – IMMP1.5W-BC – IMTP1.5W – IMTP1.5W-BC – ITTP1.5W-BC - ENG ELECTROIL
Command Procedure
RESET (to restore constructor data) & press them simultaneously for 5 seconds
Starting SELF-REGOLATION CHECK After RESET, press
Table 5: Reset and Self-Regulation Check starting
During self-regulation check the velocity and pressure of the pump arrive to maximum values;
if is necessary, limit the maximum pressure before, modifying F7.
We suggest to repeat the self-regulation check after any variation of parameters, in particular
for variation of Maximum Velocity (F4) or Maximum pressure (F7), or in case of variations of the
electrical/mechanical pump conditions, that may appear after long time of working.
5.1.1 Checking the pump stop for minimum flow
At the end of the self-regulation check, done with the delivery of the pump completely closed (all of the output
valves closed) the pump shall be automatically stopping and the Inverter could show the message "MINIMUM
FLOW" by the corresponding Yellow LED. The stop is preceded by a phase of flashing LED “MINIMUM FLOW”.
Verify that the pump stopped and after that the pump re-start working when opening any valve on pump delivery.
5.1.2 Checking the stop of the pump for a dry run situation
After installing, if is possible, close the suction/intake line in order to simulate a dry run situation of the pump and
check that, after approximately 40 seconds, the pump stop and show the message “DRY WORKING” with
corresponding Red Led.
5.1.3 Group Functioning of a group of N°2 Archimede Blue Connect
The Blue Connect version of Archimede Pump Inverter is designed for a totally automatic and very simple
installation in a group of two pump inverters on the same room (maximum distance 20 meters between each
others).
The default setting (with F17=2) is good for N° 2 pumps connected in group and also for a single pump, without
any parameter change, if there isn’t any other BC inverter in the same room.
To connect in group N° 2 pump-inverters Blue Connect:
1. Supply voltage to every Inverter of the group;
2. From the Reset condition, press START and close the delivery, making the Check of the pump for every
Inverter, and wait two minutes;
3. When all check are finished, both inverters are connected, working in group, alternating every hour.
The two inverters connected in group define automatically the Master inverter and the slave inverter, without any
functioning difference, they will have the same pressure reference (possible to adjust in every inverter of the group
using + and – buttons) reading the pressure value on the same pressure transducer of the master and, in case
of failure on it, they will read the pressure on the second pressure transducer of the slave. Alternating time for the
pump priority is 1 hour.
If you need a single mode functioning of two or more Archimede BC inverters located in the same room, you have
to change the parameter F17 setting it on 1 (Single inverter mode) to each inverter.
If you have two or more groups of Archimede BC inverters on the same room set different values of frequency
on parameter F20 (example of N°2 groups in the same room: leave F20=800 MHz – default value – for the
inverters of the first group and modify F20=810 MHz for the inverters of the second group).

WARNING: setting an high Maximum Velocity (function F4) increase the performance of the
pump but can also reduce the endurance of the same for the stress of electrical and mechanical
parts.
NOTES: Check suspension function (F18-0) eliminate the Self regulation check and regulate the
pump working using a theoretical approximated curve (minimum flow stop is modifiable with F1);
If the high value of the starting current cause problems on the magneto-thermal switch protection try reduce this
current with F6 and verify that the torque remains enough.

6. PROTECTIONS AND ALARMS
N°
Alarm
type
with
ALARM led ON
Protection
Description
A1
Peak Current
The logic switches off the power instantaneously if this
value exceeds a peak that can damage the power
electronic components. Possible high starting current or
short-circuit on motor.
A2
Over-voltage
The logic switches off the current if the voltage exceeds
a maximum instantaneous limit (+15%Vn) beyond that
can damage some electronic components of the
inverter.
A3
Minimum-voltage
If the voltage goes below the minimum value (-15%Vn)
the power supply may provide a under-voltage to some
electronic components; for this the logic switches off the
current.
A4
Over-temperature
IGBT
If the temperature of the power electronic components
(IGBT) exceeds 85°C the inverter provide a thermal
protection and stops the current.
Before this stop protection the Inverter limit the current
to 90% of the value imposed (F2)
A5
Motor Over-
Current Thermal
protection
To over-current beyond a certain time defined by an I
2
t
algorithm, the inverter limit the current to protect the
motor from damage to the insulation. For the correct
functioning of this protection regulate the nominal motor
current (F2).
A6
Pressure
transducer
problem
In case of a problem or failure of the pressure
transducer, the Inverter switches off the motor current.
Re-start must be manually, pressing STOP followed by
START.
A7
Minimum flow
This protection stop the pump when all output are closed
and the flow of water is null. Do not switch on “Alarm” led.
A8
Dry working
This protection stop the pump in absence of input flow of
water. After five consecutive re-start, the stop is
permanent and switch on also the “Alarm” ledl
A9
Voltage Supply
/Motor out inversion
(ITTP1.5W-BC only)
Probably the input supply phases are inverted with the
output. Please verify the correct cable connections (fig.
14-15).
A10
Phase T Peak
Current (U6-U5)
(only IMTP-ITTP)
The logic switches off the power instantaneously if this
value exceeds a peak that can damage the power
electronic components. Possible high starting current or
short-circuit on motor.
A11
Phase S Peak
Current (U4-U3)
(solo per IMTP-ITTP)
The logic switches off the power instantaneously if this
value exceeds a peak that can damage the power
electronic components. Possible high starting current or
short-circuit on motor.
A12
Phase R Peak
Current (U2-U1)
(solo per IMTP-ITTP)
The logic switches off the power instantaneously if this
value exceeds a peak that can damage the power
electronic components. Possible high starting current or
short-circuit on motor.
Table 7: Protections and Alarms
All Alarms from A1 to A6 (table 7) are showed with the corresponding Led on the circular Led bar and the red
Alarm Led, that is flashing if the protection have automatic re-start otherwise is fixed if the protection need a
manually re-start doing STOP then START.

15 IMMP1.1W – IMMP1.5W – IMMP1.5W-BC – IMTP1.5W – IMTP1.5W-BC – ITTP1.5W-BC - ENG ELECTROIL
Protections and Alarm details:
CURRENT PICK PROTECTION (A1): The Inverter stop immediately the current in case this value exceed a
maximum value limit for the electronic components
MINIMUM FLOW WORKING PROTECTION (A7): to prevent a closed delivery working, the control logic read the
motor’s working point condition; if this point is under a setting value, the system switches off the pump, and
appears on the display “Minimum Flow”. At the end of this condition, the system restarts its normal operation. The
pump curve is detected by the initial self-regulation check.
DRY WORKING PROTECTION (A8): To avoid that the pump can continue to operate after a problem in absence
of suction/intake water, the system read some information of the electric motor, in a time of 30 seconds, and when
they go below a minimum, turn off the pump and show the relative signal of alarm “Dry Working”. The inverter
tries N°5 consecutive re-start in this condition, one spaced 15 minutes of each other. After the fifth consecutive
fault, switch on the led Alarm and the re-start must be manually do, pressing STOP followed by START.
ENABLE OFF: the enable contact (float contact) is open and the led MOTOR ON is flashing.
7. SOLUTION ON THE MOST COMMON INSTALLATION AND WORKING PROBLEMS
N° Possible Problem Possible solution
1
Pressing start button the
motor don’t start or start
and stop after few
seconds and the inverter
show Over-Current alarm
or Current Pick alarm
Check if the input/output of the inverter are respectly connected between line and motor, without
inversion (Warning: input/output inversion can damage the electronic board of the inverter).
Check the correct connection of the pump (star/delta): possible mistake.
Check if all the phase-wires to the motor are connected good and the three current are balanced.
Check if the motor power size is not so high on respect to the inverter size.
Check if the inverter is not on Master-Slave condition (F17)set to slave, without the Master inverter
connected and switched on: in this situation waiting 30s after pressing start button, the inverter will start
automatically alone.
2
Pressing start button the
motor don’t start or start
and stop immediately and
the inverter show Under
Voltage alarm
Check that all the input voltage supply wires are connected good on the entrance of the inverter: if the
inverter input is three-phases but on the connection there are only two, the inverter switch on and can
start the motor, but after haven’t enough power to supply it.
Check that before the inverter the supply line wires size are good to have a limited voltage drop, then a
sufficient voltage value on the inverter.
3
During working at the
maximum power the
inverter reduce
continuously the output
power to the motor then
stop the motor and the
inverter show Over
Temperature IGBT alarm
/Inverter Temperature
alarm
Temperature of the electronic board of the inverter is too high and the inverter must remain stop for few
minutes to reduce the internal temperature before the automatic restart.
Be sure that the inverter stand on a wall, in vertical position, protected from directly sunlight, and the air
flow is totally free;
the inverter cannot work continuously at the maximum power with a ambient temperature higher than
40°C and with high temperature can reduce automatically the output power (-10%, -20% then stop for
few minutes).
4
Pressure Transducer
don’t measure the correct
pressure value (error > 1
Bar)
Check if the pressure transducer is connected on the delivery of the pump on a correct position, not so
close to the impellers and before the valve to close the flow.
5
Pressure Transducer
measure a pressure too
high when the motor is
running then the Inverter
reduce the motor velocity
at the minimum value
(low frequency)
Check that the pressure cable is separated from the motor cable, that is a source of noise; specially
when the cable of the pressure transducer is too long (long distance between inverter and motor) it’s
very important to use a shielded type two wire cable, as far as possible to the motor supply cable.
Connect the shield to ground only on one terminal, if possible connect it directly on a metal screw to
ground near the motor.
6
The Inverter cannot work
because remain in
Pressure Transducer
Problem alarm condition
Check If the wires of the pressure transducer are correctly connected brown on +, white on S contact on
the board.
Check wiring connection on the cable of the pressure transducer.
Warning: In case you need to cut the pressure transducer cable to add a longer cable be sure to switch
off the inverter at least 1 minute before to cut this cable, otherwise you can cause a short circuit on the
transducer input of the electronic board (damage) if the internal capacitors are not totally discharged.
7
The distance between
Pressure transducer and
Pump is high (long pipe)
and the pressure
continuously go up and
down
You must reduce the velocity of the feedback control reducing the Proportional factor (F13) and the
Integral factor (F14). Try to set these values to half and test the system, then, if not enough, reduce
more and test again until the pressure control remain stable.
8
The Inverter stop the
motor for Minimum Flow
with a high flow condition
and then re-start and stop
again, continuously
A small water membrane Tank charged with 1.5-2 Bar air pressure is required for a correct working;
check it.
The condition may also caused by a not correct pump curve saving during the automatic check: possibly
the delivery was not totally closed and the Inverter checked a higher curve of the pump; reset the
inverter (STOP and – button during 5 seconds) and repeat the automatic check closing totally the outlet
and try again the functioning.
Verify if there is a no-return inlet valve on the pump and if it’s working good without loses.

16 IMMP1.1W – IMMP1.5W – IMMP1.5W-BC – IMTP1.5W – IMTP1.5W-BC – ITTP1.5W-BC - ENG ELECTROIL
It’s possible to reduce the flow before stopping reducing the parameter Minimum Flow Power stop (F1).
9
The inverter don’t switch
off the pump when the
valve on delivery is totally
closed
Probably check was done with pump not perfectly filled up; remake the check procedure after a
complete filling of the pump and try again if pump switch off correctly in minimum flow condition. If the
problem remain, try to grow up the function F1, 2 point every time and testing pump, till find the correct
working.
10
The hydraulic system
have a big tank (>40 l)
and, after check did
correctly with closed
delivery, the pump stop
for minimum flow with a
high flow, and then re-
start and stop again,
continuously
Probably during the automatic check there was a flow of water to full up the big tank, for that the pump
curve saved by the inverter is not the correct curve (with null flow and maximum pressure).
Maintain full of water the tank (pressure near maximum value); reset the inverter (STOP an – during 5
seconds) then repeat the automatic check pressing start. When the check finish try to work again testing
the minimum flow stop condition of the motor that must be with a small flow.
11
The Inverter stop the
motor for Dry Working
condition
Sometimes the problem is caused by the same Automatic Check error that previous point (see possible
solution like above).
In other cases possibly there is air mixed with the water on the inlet of the pump (verify pipes and
junctions).
Warning: this problem can be more often on some types of small pumps where the Power absorbing Vs
Flow curve is close to the horizontal (ex: Jet pumps).
12
The pump don’t switch off
for dry working when the
inlet pipe and the pump
are empty
In normal working condition, with pump and pipes filled up, make a Reset (Stop and – buttons
maintaining pressed at the same time during 5 seconds) and remake a check procedure (Start,
maintaining closed delivery). If the problem remain verify that pump haven’t any defect (fault seal,
impellers, etc) that can cause a big power absorbing also without water, in dry condition.
13
A group of two or more
inverters cannot
communicate between
each other in Master-
Slave mode
Check the correct radio connection between the inverters (F17 must be =1).
Check also the radio frequency on F20: must be the same for all the inverters on the same group of
pumps.
The distance between the inverters on a group on the same room cannot be more than 15 meters
without shielding iron wall between the inverters.
14
The Inverter conduct on
the input voltage supply
line electromagnetic
noises that disturb other
electronic devices
Check Ground cable connections (Ground system must be radial type, with resistance less than 10
Ohm).
All the Inverters have an internal Input EMC filtering stadium, but is available also an additional EMC
Input filter (various types, contact the service) for bigger noise suppression with sensitive devices
connected on the line.
15
With a long cable
between Inverter and
Motor sometimes the
inverter stop the motor in
Pick Current alarm
The motor can have high pick voltage value caused by the high frequency of the PWM combined with
the high capacitance to ground of the long cable: we suggest to use an additional inverter output filter for
cable longer than 40 meters, connecting it directly on the Inverter output. Available various types of
output filters, contact the service to receive informations.
16
The Differential Circuit
Breaker on the line
sometimes switch off the
inverter
Check the Ground system resistance (must be less than 10 Ohm).
Use only differential circuit breaker type A (specific for Inverters).
17
The Magneto-Thermal
Circuit Breaker on the line
switch off the inverter
when the pump run at the
maximum power
All the inverters may have a high pick value of the sinusoidal caused by the harmonics (5
th
, 7
th
, 11
th,
etc.) and depending by the resistance of the line, but this condition don’t increase the energy absorbing
value depending by the area under this current curve. Only you need to use a Magneto-Thermal Circuit
Breaker with a higher Current value than the value that you can use for the direct pump controlled.
Usually it’s enough a switch one step higher than the switch useful for the simple motor (see table of the
Magneto-Thermal protection suggested on the handbook).
