5.2 ELECTRICAL CONNECTIONS
Basic interconnection diagram
Power connection: Mains-Drive.
The drive power supply must be three-phase. A transformer MUST BE used. It must be used to
filter the start-up current to the maximum value allowed by the unit.
See characteristics on page 10.
(*) 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.
Cartridges 5SE0 016-OY and 5SE0 020-OY from Siemens are good for this application.
A thermal switch may optionally replace the fuses.
Important: The secondary windings must have a star connection with its middle point connected
to ground.
