Damage due to an incorrectly connected KTY temperature sensor
If the KTY temperature sensor was not connected with the correct polarity, motor
overheating may not be detected.
• Connect the KTY temperature sensor with the correct polarity.
Danger to life due to 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 protectiv
e
s
eparation.
• If safe electrical separation cannot be guaranteed (for linear motors or third-party
motors, for example), use a Sensor Module External (SME120 or SME125) or Terminal
Module TM120.
