ELECTRICAL CONNECTION
Electrical installation must be undertaken by qualified personnel who are in possession of the necessary technical qualifications required
by the country in which the unit is to be installed.
WARNING :
ntenance operations, connections and repairs must be undertaken after the machine has been isolated. For any type of inter-
vention, it is essential to cut off the power supply to the machine.
Verify that the line voltage corresponds to that indicated on the identification plate. The power supply cable must be well extended (avoid
bends or overlaps), in a position not exposed to possible blows or handling by minors, and it should not be in the vicinity of liquids, water
or heat sources. Never damage the power cable (if this happens, have it replaced by qualified personnel).

Connection to the electricity supply
Only use diameters and types of power cables recommended by the manufacturer as indicated in Tab. 1 and Tab. 2. Choose an appropria-
te cable, according to the equipment's power consumption as indicated on the identification plate. The electrical power supply unit must be
equipped with an automatic magnetothermal differential device with an efficient ground connection, as required by the relevant safety
GB
regulations in force. In three-phase models, the power line and any optional control devices must be connected to the main panel Qa
(see attached diagrams to identify the panel), and in the case of single-phase models, to the Qa panel. Pass the cabling through the
appropriate cable holder; following its insertion, tighten the cable holder to ensure that it is correctly secured.

The connection of the unit's power cable must be carried out in accordance to the wiring colour scheme.
Important:The equipment must be grounded.
In the vicinity of the power terminals, the yellow/green cable must be left longer than the other power cables in order to guarantee
that in the case of the power cables being stretched, it will be the last cable to become disconnected from the terminals.
If the equipment is assembled in banks together with other machines, an equipotential system must also be included:
the connection is achieved by means of a terminal indicated by the symbol
The diameter of this cable (yellow/green) must be equal to, or greater than, the maximum diameter of power cable.
Connection of the control devices (optional)
All the units are supplied in a standard configuration, without any specific device for regulating temperature. The following OPTIONALS
are available on request:
- Electronic speed controller 230V~ 10A
- Electronic speed controller 230V~ 16A
- Electronic speed controller 400V~12A
- Electronic speed controller 400V~20A
