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 specific voltage.
If you use defective cable ports, you could suffer an electric shock.
•
Only mount and remove the electrical components if you are qualified 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 specific 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.
NOTICE
Destruction of the motor
Removing the connection block for the motor feeder cables at the motor can destroy the
motor.
•
Never remove the connection block on the motor for the motor feeder cables (power and
signal cables).
The cables for the power connection are brought out at the front of the stator (NDE flange).
Connect the open ends of the cables in a terminal box. The machine manufacturer must
provide the terminal box (minimum degree of protection IP54). Enough installation space
must be available in the axis structure. Refer to Chapter "Shielding, grounding and
equipotential bonding".
