Injury caused by moving or ejected parts
Contact with moving motor parts or drive output elements and the ejection of loose motor
parts (e.g. feather keys) out of the motor enclosure can result in severe injury or death.
• Remove any loose parts or secure them so that they cannot be flung out.
• Do not touch any moving parts.
• Safeguard all moving parts using the appropriate safety guards.
Fire due to incorrect operation of the motor
When incorrectly operated and in the case of a fault, the motor can overheat resulting in fire
and smoke. This can result in severe injury or death. Further, excessively high temperatures
destroy motor components and result in increased failures as well as shorter service lives of
motors.
• Operate the motor according to the relevant specifications.
• Only operate the motors in conjunction with effective temperature monitoring.
• Immediately switch off the motor if excessively high temperatures occur.
Burns and thermal damage caused by hot surfaces
Temperatures above 100 °C may occur on the surfaces of motors, converters, and other drive
components.
Touching hot surfaces may result in burns. Hot surfaces may damage or destroy temperature
sensitive parts.
• Ensure that temperature-sensitive parts do not come into contact with hot surfaces.
• Mount drive components so that they are not accessible during operation.
Measures when maintenance is required:
• Allow drive components to cool off before starting any work.
• Use appropriate personnel protection equipment, e.g. gloves.
