Electricity supply, Preliminary operations

6.1.2. Electricity supply

The machine is supplied ready for connection according to the required electrical specifications. Before connecting the machine ensure that the plate details (fig. 1) comply with those of the electric distribution network.

The electrical connection cable must be directly connected to the connection provided according to current legislation. Ensure that the earthing system is efficient and in compliance with current legal re- quirements.

The earthing system and the lightening protection system must be realized in accordance with the provisions of current legislation.

For the supply network use a cable in compliance with standards with protective conductor (earthing wire).

For three-phase power use a cable with 5 conduc- tors ( 3 phases + neutral + earth).

For single phase power supply use a cable with 3 conductors (phase + neutral + earth).

In both cases it is necessary to provide an auto- matic differential switch (Fig. 6) at the start of the power cable, complete with magnetic release ele- ments in accordance with the identification plate details (Fig. 1). The contact opening must be equivalent or over 3 mm.

Remember that each machine must be fitted with its own safety elements.

WARNING:

Should the power supply cable be dam- aged it is to be replaced by the manufac- turer or by its technical assistance serv- ice or by person with equivalent qualifica- tion, in order to prevent any risks.
