INSTALLATION AND USE
DG FIT is an inverter-based electronic control device designed for single-
phase surface or submersible pumps. It is utilized for water supply in
residential, commercial, and irrigation applications, and is compatible with
all types of pressurization systems, including existing ones.
DG FIT ensures maximum comfort, extends the system’s service life, and
facilitates significant energy savings.
DG FIT protects the pump from:
※ Dry running
※ Overcurrent
※ Overvoltage
※ Undervoltage
※ Overheating
※ Short circuit
PRODUCT DESCRIPTION
DG FIT is a wall-mounted frequency converter which, equipped with a pressure sensor, allows the rotation speed of the motor to adjust dynamically according to the amount of water required, thus ensuring constant pressure in the system.
DG FIT is characterised by:
※ A display and keypad for easy, step-by-step setup of operating parameters with two levels of adjustment:
– BASIC, for setting pressure and current;
– ADVANCED , for customizing the inverter for specific system needs.
※ Electronic components are cooled by an integrated fan to ensure heat dissipation.
※ Integrated expansion board, which allows:
– RS 485 communication for up to three DG FIT to talk to each other
– configuration of a dry input contact (e.g. float, double set point)
– configuration of a dry output contact (e.g. alarm)
※ Input signal: pressure sensor
※ Arrangement for wall connection
ADVANTAGES IN USE
※ Easy installation, adjustment and setting.
※ Energy saving due to lower absorption of the pump.
※ Control of hydraulic and electrical operating parameters and protection
against faults.
※ Reduced noise operation.
※ Longer pump life.
※ Possibility to connect up to three devices to create pressurization units

TYPICAL INSTALLATION
N.B.: it’s neceadvisable to install a membrane EXPANSION TANK downstream of
the inverter to:
※ decrease pump start frequency
※ absorb excess pressure from the system, like water hammer
