Special Warnings; Responsibility; General Information - DAB PWM II 230 D 4.7 Instructions Pour L'installation Et La Maintenance

Safety
Use is allowed only if the electric system is in possession of safety precautions in accordance with the regulations
in force in the country where the product is installed (for Italy CEI 64/2).
Pumped liquids
The machine has been designed and made for pumping water, free from explosive substances and solid
particles or fibres, with a density of 1000 Kg/m³, a kinematic viscosity of 1mm²/s and non chemically
aggressive liquids.
The power supply cable must never be used to carry or shift the pump.
Never pull on the cable to detach the plug from the socket.
If the power cable is damaged, it must be replaced by the manufacturer or by their authorised technical
assistance service, so as to avoid any risk.
Failure to observe the warnings may create situations of risk for persons or property and will void the product
guarantee.

Special warnings

Before working on the electrical or mechanical part of the system, always turn off the mains
voltage. Wait at least five minutes after the power supply to the machine has been switched
off before opening the appliance. The capacitor of the continuous intermediate circuit
remains charged with dangerously high voltage even after the mains voltage has been
switched off
536 class 1, NEC and other relevant standards).
Mains and motor terminals may carry dangerous voltage even when the motor is stopped.
In specific calibration conditions, after a power failure the converter may start automatically.
Do not operate the appliance when exposed to direct sunlight.
This appliance may not be used as an "EMERGENCY STOP mechanism" (see EN 60204, 9.2.5.4).
The Manufacturer does not vouch for correct operation of the electropumps or answer for any damage that
they may cause if they have been tampered with, modified and/or run outside the recommended work range
or in contrast with other indications given in this manual.
The Manufacturer declines all responsibility for possible errors in this instructions manual, if due to misprints or errors
in copying. The Manufacturer reserves the right to make any modifications to products that it may consider necessary
or useful, without affecting their essential

1 GENERAL INFORMATION

Inverter for electropumps designed for pressure boosting in hydraulic plants by measuring the pressure and the flow.
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.
. Only firmly wired mains connections are admissible. The appliance must be earthed (IEC
