6.1.2. Electric supply

The machine is supplied ready for connection
according to the required electrical specifications.
Before connecting the machine ensure that the plate
details comply with those of the electrical main sup-
ply.
The electrical connection cable must be directly
connected to the connection provided according to
current legislation.
The earthing and the lightening protection system
must be realized in accordance with the provisions
of current legislation.
For the main power supply be sure to use cable that is
compliant with all local, state and federal regulations
and be sure that it is properly earthed.
For three-phase power use a cable with 5 conductors

For single phase power supply use a cable with 3
conductors (phase + neutral + earth).
In both cases it is necessary to provide an automatic
differential switch (Fig.5) at the start of the power cable,
complete with magnetic release elements in accord-
ance with the identification plate details (Fig. 1). The
contacts must have a 3mm or greater opening with a
dispersed current protection of 30mA.
Remember that each machine must be fitted with its
own safety elements.
WARNING:
Should the machine's power cable become
damaged it is to be replaced by the manu-
facturer or by a factory trained and certified
technician, in order to prevent any risks.
