Danger to life due to electric shock in the event of voltage flashovers on the temperature
sensor cable
Voltage flashovers in the signal electronics can occur in motors without safe electrical
separation of the temperature sensors.
• Only use temperature sensors that fully comply with the specifications of the safety
• If safe electrical separation cannot be guaranteed (for linear motors or third-party
NOTICE
Risk of the motor overheating due to an incorrectly connected KTY temperature sensor
A KTY temperature sensor connected with incorrect polarity cannot detect if the motor
overheats.
• Always connect the KTY sensor with the correct polarity.
