result in increased failures and reduced service lives of motors.
Comply with the specified coolant requirements for the motor.
•
WARNING
Danger to life due to fire as a result of overheating caused by incorrect operation
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.
•
CAUTION
Risk of injury due to touching 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.
