ELECTRICAL CONNECTION

DANGER - ELECTRIC SHOCK RISK
The panel must be powered by a differential device with on/off power under 30 mA.
DANGER - ELECTRIC SHOCK RISK
Check that the power supply is provided with an efficient ground installation in accordance with the current
regulations.
ATTENTION
The single-phase panel does not have a master switch.
ATTENTION
Check that the voltage and frequency indicated on the nameplate correspond to those of the available power grid.
ATTENTION
The power supply is equipped with differential circuit breaker with the sensitivity required by the regulations in
force for this type of equipment.
ATTENTION
Before connecting the power supply cable to the control board, check that it has sufficient dimensions to
support the maximum voltage required by group pumps.
ATTENTION
The connection of the distribution boards to the power grid must be done according to indications reported on
the electric connection scheme situated in the control board.
Our units are delivered with "LIV" jump terminals (L1-L2 for the single-phase, Fig.2; 5-6 for the three-phases,
Fig.3).
ATTENTION
In this case the unit is not protected against dry operation. It is therefore necessary to remove the electric
bridges and connect them to the control device selected.
FLOAT SWITCH
The float must be installed in the tank and connected thanks to two wires to the special terminals on the control board.
INVERTED MINIMAL PRESSURE SENSOR
In the case where the group is fed by a water duct under pressure (for example municipal water system), it is necessary to install a
minimal pressure sensor which prevents from the working of the group if the pressure in the duct descends below the preset value.
