8.6.1

 

Inspections in the event of faults 

Natural disasters or unusual operating conditions, such as overloading or short circuit, are 

faults that overload the motor electrically or mechanically. 
Immediately perform an inspection after such faults.  
Correct the cause of the fault as described in the respective remedial measures section. 

Repair any damage to the motor.
