Requirement
Electric shock when the motor temperature sensor insulation fails
When connecting temperature sensors which are not isolated from the motor power circuit
according to safe electrical separation, arcing to the signal electronics may 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,
Only use the temperature sensor input of the Motor Module if the following conditions are
fulfilled:
• The connected motors are not equipped with an integrated DRIVE-CLiQ interface.
• The temperature values are not acquired via another component (Sensor Module Cabinet,
Sensor Module External, Terminal Module).
