Manual.
NOTICE
Motor overheating due to an incorrectly connected KTY temperature sensor
A sensor connected with the incorrect polarity cannot detect the motor overheating.
Connect the KTY temperature sensor with the correct polarity.
For more information on the temperature sensors and how to use them, see the SINAMICS
S120 Commissioning Manual, Section Temperature sensors for SINAMICS components.
The maximum length of the temperature sensor cable is 300 m. The cables must be shielded. For
cable lengths >100 m, cables with a cross-section of ≥1 mm² must be used.
Danger to life from electric shock due to insufficient safety isolation
Only temperature sensors that meet the safety isolation specifications stipulated in EN
61800-5-1 may be connected to terminals "+Temp" and "-Temp".
Use a Sensor Module External (SME120 or SME125) or Terminal Module TM120 if safe electrical
separation cannot be guaranteed (for linear motors or third-party motors, for example).
