General safety instructions
1.1 General safety instructions
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 inadequate cooling
Inadequate cooling can cause the motor to overheat, resulting in death or severe injury as a
result of smoke and fire. This can also result in increased failures and reduced service lives
of motors.
• Comply with the specified cooling requirements for the motor.
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.
Burn injuries caused by hot surfaces
In operation, the motor can reach high temperatures, which can cause burns if touched.
• Mount the motor so that it is not accessible in operation.
Measures when maintenance is required:
• Allow the motor to cool down before starting any work.
• Use the appropriate personnel protection equipment, e.g. gloves.
