NOTE

The specified circuit examples apply for the PTC temperature sensor from the M11 Motor Catalog (motor protection using PTC thermistors, Code Z = A10 – A16) - that is used for the 1LA and 1LG Siemens motors.

NOTE

In order to avoid noise from being coupled into the drive inverter electronics - with the associated disturbances - none of the free conductors in the motor cable may be used to connect the temperature sensor to the drive inverter. The temperature sensor must be connected to the drive inverter using a separate cable (if possible, using a shielded cable).
