1. GENERAL INFORMATION

Inverter for three-phase pump designed for the pressurisation of hydraulic systems and also optionally for flow measurement .
The inverter maintains the pressure value in a hydraulic circuit constant by varying the rpm of the electric pump; the inverter is
switched on and off by sesnors according to hydraulic requirements.
There are a wide range of operating modes and optional accessories. By means of the various possible settings and availability of
configurable inputs and outputs, operation of the inverter can be adapted to meet the requirements of all systems. 6 SIGNIFICATO
DEI SINGOLI PARAMETRI specifies the various settable values: pressure, protection cut-out trip, frequency of rotation, etc.
In this manual the pump will also be referred to in the abbreviated form "inverter", when dealing with common characteristics.
