6.1 Safety instructions for electrical connections
NOTICE
Destruction of the motor if it is directly connected to the three-phase line supply
The motor will be destroyed if it is directly connected to the three-phase line supply.
• Only operate the motors with the appropriately congured converters.
WARNING
Risk of electric shock due to incorrect connection
If you incorrectly connect the motor this can result in death, serious injury, or extensive
material damage. The motors require an impressed sinusoidal current.
• Connect the motor in accordance with the circuit diagram provided in this documentation.
• Refer also to the documentation for the drive system used.
WARNING
Risk of electric shock
Voltage is induced at the power connections of the primary section each time a primary section
moves with respect to a secondary section - and vice versa.
When the motor is switched on, the power connections of the primary section are also live.
If you touch the power connections you may suer an electric shock.
• Only mount and remove electrical components if you have been qualied to do so.
• Only work on the motor when the system is in a no-voltage condition.
• Do not touch the power connections. Correctly connect the power connections of the
primary section or properly insulate the cable connections.
• Do not disconnect the power connection if the primary section is under voltage (live).
• When connecting up, only use power cables intended for the purpose.
• First connect the protective conductor (PE).
• First connect the power cable to the primary section before you connect the power cable to
the converter.
• First disconnect the connection to the converter before you disconnect the power
connection to the primary section.
• In the nal step, disconnect the protective conductor (PE).
