WARNING
Risk of electric shock due to incorrect connection
There is a risk of electric shock if direct drives are incorrectly connected. This can result in death,
serious injury, or material damage.
• Motors must always be precisely connected up as described in these instructions.
• Direct connection of the motors to the three-phase supply is not permissible.
• Consult the documentation of the drive system being 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).
WARNING
Risk of electric shock as a result of residual voltages
There is a risk of electric shock if hazardous residual voltages are present at the motor
connections. Even after switching o the power supply, active motor parts can have a charge
exceeding 60 μC. In addition, even after withdrawing the connector 1 s after switching o the
voltage, more than 60V can be present at the free cable ends.
• Wait for the discharge time to elapse.
