1) When utilized acc. to M0 (100 K), a series braking resistor must be used in order to prevent partial de-magnetiza-
tion.
When utilized according to M0 (60 K), the additional braking resistor is not required.
2) It is absolutely prohibited to short-circuit the winding when using smaller supplementary resistors than those speci-
fied. When braking from the rated speed, the resistors listed prevent partial de-magnetization of the rotor.
