(a)CNM10 connects to the output transformer, CNM11 connects to the input transformer.

(b)Thermal switch sensors are mounted on the coils of the transformer.

(c)The thermal switch sensor will be open when the transformer coil’s temperature exceeds 150. MCU can detect the temperature status through IPRT Temp (51) and OTRT Temp (61).

Note: For international models (SU20KX, SU40KX, SU60KX and SU80KX), short-pins must be inserted into CNM10 and CNM11.
