ELECTRIC CONNECTION

WARNING
Ensure tension and frequency of pump (read plate) and power supply are same.
DANGER - ELECTRIC SHOCK RISK
Installer must make sure that electric current network has ground wire conforming to current laws.
DANGER - ELECTRIC SHOCK RISK
Make sure that electric current network is provided with a high-sensitivity circuit breaker D =30
mA (DIN VDE 0100T739)
WARNING
Before connecting the power supply cord to the clamps on the command panel, make sure that the cord is
able to withstand the nominal current of the unit.
DANGER
The power cable must be replaced by qualified personnel only.
Electric connections must be carried out by skilled staff only, in accordance with the manufacturer' s instructions
enclosed to the electric equipment and the motor. It is advisable to install a protection device upstream, of ade-
quate dimensions (in accordance with the current values indicated on the nameplate) to prevent voltage peaks and
overloads.
Cables should be selected in function of the absorption in Ampere, indicated on the nameplate. Cables should be
dimensioned in accordance to the power to transmit, of the distance from the control page and the starting system
of the submersed motor. Cables should guarantee a submersed operation, have waterproof joints and show no signs
of abrasions or holes.
The control board should be equipped with all the protection devices and equipment to manage and drive the
hydraulic unit. More specifically, it is necessary to guarantee a protection against overcurrent and short circuits.
Protections against the loss of phases, the lowering of voltage and the lack of water in the well are recommended
but not compulsory.
