ELECTRICAL CONNECTIONS
Power connection: Mains-Drive.
The drive power supply must be three-phase. The use of a transformer is not a must.
(*) Recommended values. They are slow general purpose fuses. If they are installed on the Mains
input lines, their maximum currents will depend on the value of the Mains voltage.
A thermal switch may optionally replace the fuses.
Important: The secondary windings must have a star connection with its middle point connected
to ground.
