5. PLUGGING THE MACHINE TO THE ELECTRICITY
The extension cable used to feed the machine needs to have a minimum section of 4x2.5 mm
meters long. For a superior distance 4x4 mm2 can be used. In one of its ends, it is needed to connect a base
normalised aerial of 3P+T or 3P+N+T compatible with the machine switch and in the other end, one normalised aerial
pin of 3P+T ó 3P+N+T compatible with switchboard exit.
Machines with electrical motor should always be connected to a normalised switchboard that
disposes of a magneto-thermal switch and a differential in accordance with the characteristics of the
motor:
3Kw /4 HP, three phase at 400V, 15A magneto-thermal and 15A/300mA differential.
3Kw / 4 HP, three phase at 230V, 20A magneto-thermal and 20A/300mA differential.
4Kw /5,5 HP, three phase at 400V, 15A magneto-thermal and 15A/300mA differential.
4Kw / 5,5 HP, three phase at 230V, 20A magneto-thermal and 20A/300mA differential.
The machine electrical tension is visible on the voltage indication next to the top of engine terminals and on the
machine characteristics plate.
WARNING: Do not plug the machine to the electricity if you are not sure of the available electrical
tension. If the tension is not correct, the engine will undergo irreparable harm or out of service.
WARNING: Never manipulate the power cables or any electrical equipment of the machine, if you
have not totally unplugged the machine from the electricity.
IMPORTANT: It is appropriate to change the position of the bridge plates in the engine terminals. It is also
important to change the adhesive labels indicating the voltage, to reflect the change made.
