2. Non-return valve. Not required others non-return valves in the delivery pipe.
3. Pressure transducer. The 4-20 mA, 10 bar type,
EMC according EN 61000-6-2.
4. Accumulator.
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.

The motor must be connected to a 230 V power supply source.
The cable (1) supplied with the inverter must be connected to the motor.
If you wish to activate the 60Hz motor output, select the corresponding parameter in the menu.
Make sure that electrical consumption shown on the motor's data plate does not exceed that supplied by the
inverter.
DANGER. Risk of electrocution. Always connect the supplied grounding cable (2) between the motor
and inverter set.
