WARNING
Danger of severe injuries caused by unexpected movements of the motor
Unexpected movements of the motor may cause death, serious injury (crushing) and/or
property damage.
• Never work in the vicinity of rotating parts for a switched-on machine.
• Keep persons away from rotating parts and areas where there is a danger of crushing.
• Ensure that the axis transversing angle is free of any obstruction.
• Check before switching on the commutation! Also observe the instructions of the drive
system being used.
• Set the motor current limiting too low values.
• Set the speed limitation to small values.
• Monitor the end positions of the motor.
WARNING
Electrical shock hazard
Every movement of the rotor compared with the stator and vice versa induces a voltage at the
stator power connections.
When the motor is switched on, the stator power connections are also at a specic voltage.
If you use defective cable ports, you could suer an electric shock.
• Only mount and remove the electrical components if you are qualied to do so.
• Any work carried out at the motor must always be done with the system in a no-voltage
condition.
• Do not touch the cable ports. Correctly connect the stator power connections, or insulate
them properly.
• Do not disconnect the power connections when the stator is under voltage (live).
• Only use the specic power cables intended for the purpose.
• First connect the protective conductor (PE).
• Connect the cable shield through a wide area.
• First connect the power cable to the stator before you connect the power cable to the
inverter.
• First disconnect the connection to the inverter before you disconnect the power connection
to the stator.
• Disconnect the protective conductor PE last.
