Fundamental safety instructions
1.1 General safety instructions
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.
