Inverter drive of 400 V class motor

The Instruction Manual says that "When the 400 V class motor is driven by the inverter, use an insulation-enhanced motor." What risks are probable when a non-insulation-enhanced motor is used?
Give some concrete examples of phenomena that may occur.
Category : 


When the wiring between the inverter and motor is long, surge voltage occurs at the terminal of the motor.
This surge voltage deteriorates insulation of the motor and a layer short circuit may occur with the motor coil.
