EARTHING

It is essential to earth the unit.
To this purpose, it is necessary to connect to an efficient earthing system the terminals marked with the symbols (
on the line-receiving terminal box. The earthing system should comply with the law in force.
SPECIFIC WARNINGS
The electrical safety of this unit is assured only when it is correctly connected to an efficient earthing system as stated
in the electrical safety regulations in force; the Manufacturer declines any responsibility for the non-compliance with
these safety regulations.
It is necessary to verify this fundamental safety requisite and, in case of doubt, ask for an accurate testing of the system by

POWER SUPPLY CABLE

The unit is supplied fitted for the following voltages: 3N AC 380...415V; 3 AC 220...240V; 1N AC 220...240V 50Hz.
The flexible cable for power supply connection should not have characteristics lower than the rubber insulation type H07RN-F.
The cable should be inserted through the cable clasp and firmly fastened. Furthermore, the supply voltage with the unit
functioning should not go outside the value of the nominal tension ±10%.
3.3

EQUIPOTENTIAL

The unit should be included within an equipotential system whose efficiency must be tested according to the law in force.
The screw marked with the label "Equipotential" is located near the terminal box on the base.
3.4
