<p>Thermistor monitoring arrangement of an alternating-current electric motor controlled by a power transformer, such as a frequency converter, for at least one thermistor monitoring the temperature of the motor, in which is a power transformer (200), in which is a power stage (203) and a control unit (204), controlling an alternating-current electric motor (201) provided with a thermistor (202), and into which power transformer, such as a frequency converter, an input circuit connected to a thermistor located in the motor is integrated, to which input circuit a safety circuit (a so-called Safe Stop circuit) that prevents unexpected starting or ensures safe stopping of the frequency converter is connected.
