Danger to life due to touching a live part when the insulation is damaged as a result of
the high-voltage test
The motor insulation can be damaged when a motor high voltage test is carried out. You
can get an electric shock when touching live components. Further, electronic components
can be destroyed. The components involved include temperature sensors and encoders.
• Do not carry out a high-voltage test on the motor.
WARNING
Danger to life as a result of rotating output elements and loose parts that are flung out
Rotating output elements and feather keys that are flung out while the motor is running can
result in severe injuries.
• Remove any loose feather keys or secure them so that they cannot be flung out.
• Do not touch any rotating parts.
• Secure output elements by using the appropriate safety guards.

The motors can have surface temperatures of over 100 °C. Temperature-sensitive parts in
contact with the motor or attached to the motor can be damaged. Temperature-sensitive
parts include cables and electronic components.
• Never attach temperature-sensitive parts to the motor.
