Fail-safe digital inputs
An F-DI consists of a digital input and a second digital input to which the cathode of the
optocoupler is connected.
Temperature sensor input
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.
Further information regarding the temperature sensor may be found in the SINAMICS S120
Commissioning Manual, "Temperature sensors for SINAMICS components" section.
