documentation must be used for sizing the power supply cable.
WARNING
In the event of installations that do not comply with the directions given in this chapter, the
manufacturer’s liability ceases, along with the validity of the CE Declaration of Conformity.
The electrical lines must be laid in accordance with requirements of the laws applying in the place of installation, and in
any event:
•
they must be laid with cables of adequate section for the power of the fan and the length of the line itself;
•
they must make an effective earth connection;
•
they must have isolating devices and automatic protection against overload and short circuits.
Before activating the electrical supply to the machine by turning the isolator switch to position On, a series of checks must
be made:
•
check that the voltage and frequency of the power source correspond to those indicated in the equipment technical
data and electrical diagram;
•
check that the supply cables and the conductor providing external protection are correctly connected;
•
check that the connections in the control and power circuits are properly tight;
•
check that the intensity of the short-circuit expected at the connection terminals is compatible with the breaking
power of the protection switch upstream of the electrical panel;
