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.
