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 booster set is designed to start automatically. Make hydraulic connections and
to prime the pumps before making any electrical connections.
The connection of the control panels must be performed by a qualified electrician
in accordance with the present electrical standards.
The booster set and control panels must be connected to an efficient earthing
system in accordance with the electrical standards of the country in which it is
installed.
The connection of the earth must be performed first.
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.

weather conditions.
• When handling the set (tank), lift it from the bottom of the tank and make sure area
where the tank will be sited is clean and level.
• Do not lift the set by the delivery manifold: risk of damage to the inverter modules.
• Position the AquaMaxx set in such a way that any maintenance jobs can be carried
out without difficulty.
• Ensure that the system pipes are independently supported and do not weigh down
on the set manifolds so as to avoid deformation or breaking of any of its
components.
It is also advisable to insert vibration-damping couplings on the system manifolds.

200L, 300L & 450L
Make the intake section following all the precautions necessary to keep load losses
to a minimum and to avoid the formation of air pockets, for example:
• Position the set as close as possible to the power supply source
• Consider a suction pipe diameter never smaller than that of the manifold
• Lay the suction pipe horizontally or sloping slightly upwards towards the set
• Avoid using elbows or couplings that cause sudden changes in direction. If
necessary, use bends with a wide radius
Reassembly & Installation of the AquaMaxx set must be performed by skilled and
authorised installers. During installation, apply all safety behaviours issued by the
competent bodies and suggested by common sense. Install the unit in a dry well-
ventilated place. Rest the unit on a flat, regular and solid surface. The unit can only
be installed in the horizontal position.

200L, 300L & 450L
• Power up the AquaMaxx Set and follow the standard set up process
The units are delivered ready for power supply connection, which must be carried out
by a skilled, authorised installer, in compliance with the Standards in force in the
country of installation. During installation, apply all safety behaviours suggested by
law and common sense. Make sure that the electric power supply network is
protected by ground connections in compliance with Standards.
Check the correspondence between the plate data and line nominal values. Before
making the connections, make sure that the ends of the line wires are not live. Make
the connection when you are sure of the existence of an efficient ground circuit. The
ground wire must be longer than the phase wires and must be the first to be
connected during assembly and the last to be disconnected during disassembly. The
installation of a differential switch is recommended, whose nominal functioning
differential current does not exceed 30 mA (use highly sensitive differential circuit
breakers 30 mA, in Class A or AS).
For booster sets with single phase power supply (versions "M/T") connect
power supply directly to the inverter, as follows:
A: connect power supply cable to inverter (see picture).
B: motor output connection (already connected).
Single-phase power supply: the inverter power supply line voltage can vary in a
range between +/-10% of the plate power supply voltage. The power supply cable
must have 3 wires (2 phase + ground), the section of the cable to use, for line length
up to 30 m, must be at least 2.5mm2. The connection to the power supply line will be
performed on the L, N and GND clamps of the inverter (see upper picture).

200L, 300L & 450L
Connection of signal between inverters (RS485 signal): With reference to
the figure shown above, proceed in the following manner:
- Connect terminal 9 of the inverters together
- Connect terminal 8 of the inverters together
The signal wire must have 2 conductors and the minimum wire cross- section is
0.5 mm2. The maximum distance between inverters connected together in parallel
must not be greater than 10 m.
Connection of the Alarm Signal (MASTER inverter): Referring to the figure shown
above, the terminals to be connected with the signal wire (two conductions, minimum
cross section 0.5 mm2) are 2 and 3 for NC operation, and 2 and 1 for NO operation.
Connection of level sensor or other input signal (MASTER inverter): Referring to the
figure shown above, the terminals to be connected with the signal wire (two
conductions, minimum cross-section 0.5 mm2) are 5 and 4.
E-SERIES is a speed regulator powered in single-phase and three-phase for electric
a.c. single- phase and three-phase motors.
• It keeps the system pressure constant at a value defined by the user, adapting
pump performance to instant request, changing the number of motor revs.
• It carries out continuous controls on electric and functioning parameters, saving the
pumping unit from all common anomalies (over-currents, dry running, etc)
• It works in stand-alone configuration or in parallel with other inverter via serial
connection
(optional module).
• It adapts to all type of systems, even existing, while it simplifies design and
complexity of new systems, thus reducing costs, because it prevents the use of
pressure switches, important expansion
vessels, electric control boards and non-return valve.
• It activates the electric pump with starting ramps at a progressive speed, which limit
current peaks, thus lengthening the life of the
motors and allowing a great energy saving.

GENERAL TECHNICAL DATA
- Power supply voltage: single phase 230-115Vac;
- Frequency 50-60 hz
- Maximum working pressure: 10 bar
- Working position: vertical, with intake from the bottom and top exit.
E-SERIES keeps the system pressure constant (at a value defined by the user) on
variation of the flow rate requested, adapting pump performance, via variation of the
number of electric motor revs. The dimensioning of the internal hydraulic passages
and the careful hydraulic design allow the inverter to elaborate flow rates up to 200
l/min with very small pressure drops. In this configuration the system, in addition to
keeping the pressure constant by the frequency modulation of the motors, manages
the alternation of starts, in order to standardize the use of pumps. In Master / Slave
configuration the settings will be executed only on controller defined as Master. The
controller defined Slave will receives automatically settings from the controller defined
Master. If master E-SERIES is turned off, the slave E-SERIES works in a "stand
alone" mode.
For the settings of the E-SERIES please refer to attached document.
Before removing the inverter cover or starting an investigation on
the equipment, the system must be disconnected from the mains
electricity and you must wait 5 mins until the intermediate circuit
condensers, which can reach voltages up to 800V, have the time
to discharge via the built-in discharge resistors.
EMERGENCY STOP
An emergency stop can be performed while the inverter is
running, by pressing the START/STOP key. Installations with
parallel inverters only the MASTER inverter blocks the system.
An emergency stop is performed by pressing the START / STOP
switch on the MASTER inverter. If the START / STOP switch on a
SLAVE inverter is pressed the only effect is that single inverter is
stopped; not the entire system.
