WARNING
Danger to life through electric shock due to unconnected cable shields
Hazardous touch voltages can occur through capacitive cross-coupling due to unconnected
cable shields.
• Attach the cable shield to the component via terminals for the encoder system
connection.
Temperature sensor connection
For the evaluation of the temperature sensor, see function diagram 8030 in the SINAMICS
DCM List Manual.
NOTICE
Motor damage due to incorrectly connected KTY temperature sensor
A KTY temperature sensor connected with incorrect polarity cannot detect if the motor
overheats. Overheating may result in damage to the motor.
• Connect a KTY temperature sensor with the correct polarity.
WARNING
Danger to life through electric shock due to flashover to the temperature sensor cable
Flashover to the signal electronics can occur on motors without safe electrical separation of
the temperature sensors.
• Only use temperature sensors that satisfy the specifications for electrical separation
according to IEC 61800-5-1.
Note
The maximum length of the temperature sensor cable is 100 m. The cables must be
shielded.
