5.3 Connection to the electrical system
The fan is supplied without a command and control circuit, but with all the internal electrical connections already made.
At the fitting stage, the installer must set up a control panel in compliance with the requirements of standard IEC EN 60439-
1, and arrange the wiring of the fan in accordance with the instructions in standards IEC EN 60204-1 and IEC 60364.
The electrical panel of the fan must generally be equipped with the following devices (bearing EC marking as per directive
2006/95/EC):
fig.13
Lockable isolating switch.
fig.14
Magnetothermic switch (chosen to suit the power of the motor).
The need to fit a switch of differential type depends on the configuration of the electrical
system supplying the fan: it is the installer’s responsibility to make this assessment in
accordance with the instructions in standard IEC 60364.
fig.15
Red emergency stop button, mushroom type, provided with mechanical locking and
release by turning (in compliance with UNI EN ISO 13850). Operating the button must
bring about the electromechanical isolation of the power supply to the electric motor
(category 0/1 according to IEC EN 60204-1).
fig. 16
Start/stop selector switch (with characteristics compatible with the nominal current of the
motor), or main panel for managing the equipment, with control devices which act on the
electrical supply to the fan.
WARNING
Do not supply power to the fan during installation stage.
Installer must issue a declaration of correct installation in accordance with applicable legislation in the country of
use.
