Temperature sensor connection
NOTICE
Damage to motor due to incorrectly connected KTY temperature sensor
If a KTY temperature sensor is connected with incorrect polarity, it is not possible to detect
when the motor overheats. Overheating can cause damage to the motor.
• Connect a KTY temperature sensor with the correct polarity.
Information for assigning parameters to the KTY temperature sensor can be found in the
SINAMICS S120 Function Manual "Drive Functions" in the Chapter "Monitoring and protection
functions/thermal motor protection".
Note
The maximum length of the temperature sensor cable is 100 m. The cables must be shielded.
Electric shock when the motor temperature sensor insulation fails
When connecting temperature sensors which are not isolated from the motor power circuit
according to safe electrical separation, arcing to the signal electronics may occur.
• Use motors whose temperature sensors have safe electrical separation.
• Use only connecting cables and connectors with safe electrical separation between the
• If safe electrical separation cannot be guaranteed (for linear motors or third-party motors,
