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 in the event of voltage flashovers at the temperature sensor
Voltage flashovers in the signal electronics can occur in motors without safe electrical
separation of the temperature sensors.
● Use temperature sensors that comply with the specifications relating to protective
● If safe electrical separation cannot be guaranteed (e.g. for linear motors or third-party
