1) GENERAL INFORMATION.
The Speedrive inverters have been designed to adjust the speed of three
threethree
three----phase motors
phase motorsphase motors
phase motors used with water pumps.
The inverter receives a signal from the pressure transducer that is proportional to the installation's pressure. This signal
is processed and it regulates the speed of the motor to keep the pressure constant, even though the consumption of
water varies.
It can be used with 50Hz or 60Hz motors. Selecting the output frequency with the menu option.
The units have a constant pressure control system. The PI system used provides two numerical constants that are
processed by the unit to achieve a stable regulation.
This type of regulation can greatly reduce the consumption of energy when compared to unregulated systems,
since the consumption of electricity will be proportional to the consumption of water. Another of the advantages
of regulated units is the decrease in voltage surges, softening current peaks and, therefore, increasing the
working life of the pump.
WARNING: Correct compliance with the installation and operating instructions and the electrical
connection diagrams will guarantee the correct operation of the unit.
DANGER: The failure to follow the instructions in this Manual can lead to motor overloads,
diminishment in technical characteristics, reduction of the unit's working life and all types of
subsequent results, for which we decline any responsibility.

Its sole function is to compensate minor water losses in the installation, preventing
continuous pump start-ups and stops. The accumulator's volume must be at least 10% of the
nominal flow of the pump(s) installed, calculated in litres per minute. (For ex.: Multi35 5,

≥
10l) The preload pressure must be 1 bar below to
the rated pressure.

DANGER. Risk of electrocution.
Connection and grounding are compulsory.
All electrical connections will be in accordance with the IEC-60364 Regulations (electrical installation
in buildings) or the regulations in force in the destination country and local regulations.
The power supply line of equipment must be adequately protected. These protection elements will
prevent damage to persons during an electrical leakage. An exclusive power supply line is
recommended.
The system protection will be based on an earth leakage switch (I∆n = 30 mA).
The recommended earth leakage switch is "class A"
"class A""class A"
"class A" for pulsed and continuous currents, marked with the
following symbols:
The earth leakage value will depend on the number of units connected to the line and their power.

7.- Micro-switches used to configure the inverter's operation.
WARNING: All external cabling connections must use terminal tips on the ends of each cable. External
cables must comply with the corresponding electrical safety and insulation regulations. Installation
should be made by qualified service personnel.
Avoid any cable pieces from falling inside the circuit, which could lead to its destruction.
DANGER. Risk of electrocution.
If the unit has to be uncovered due to any circumstance, first disconnect the power supply and wait 5
minutes before starting work with the circuit. The circuit's capacitors store energy. There is enough
energy inside the circuit to cause a strong electric discharge, even when the unit is not powered.
