NOTICE
Damage to motor in the event of 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.
Electric shock when the motor temperature sensor insulation fails
When connecting temperature sensors, which have no safe protective separation with respect
to the motor power circuit, then arcing to the signal electronics can 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,

Type: Spring-loaded terminal 6 (Page 320)
The maximum cable length is 30 m.
Note
The two "+" and "M" terminals are jumpered in the connector. This ensures that the supply
voltage is looped through.
