Temperature evaluation of the motor
A temperature sensor (TF, TH) can be connected via terminal X20C: TF/TF1.
WARNING
Dangerous contact voltages at the terminals of the inverter when connecting the wrong temperature sensors.
Severe or fatal injuries from electric shock.
- Connect only temperature sensors with protective separation from the motor winding to the temperature evaluation. Otherwise, the requirements for protective separation are not met. Dangerous contact voltages may occur at the terminals of the inverter via the signal electronics in the event of a fault.
- Preferably use bimetallic temperature switches TH.
- The series connection of the TH contacts (normally closed) is not subject to any restriction if joint monitoring is provided.
- If the TF temperature sensors are available in motors, the temperature sensors of up to 3 motors can be connected in series.
