Siemens SINAMICS S120 Commissioning Manual page 161

NOTICE
Material damage caused by overtemperature
For thermal motor protection you must connect Temp-S. It is impermissible to not connect
Temp-S!
You can optionally connect Temp-F to a measuring instrument for commissioning or test
purposes.
In normal operation, short-circuit the Temp-F connections and connect to PE.
Note
The Temp-F temperature sensor only evaluates the winding temperature of one phase in the
primary section. However, the phases in the synchronous motor have different loads. Higher
temperatures can occur in the phases that are not measured.
Risk of electric shock
Without using a suitable protective module (e.g. TM120), for safe electrical separation it is
not permissible to connect Temp-F to a Sensor Module of the SINAMICS drive system.
The drive must always be switched into a no-voltage condition. When handling and
connecting Temp-F, when the drive is switched-on, hazardous voltages can be present at
the terminals on the motor side and at the Temp-F connecting cable.
Risk of electric shock
If a 3RN1013-1BW10 thermistor motor protection device or a suitable protective module is
not used, then for safe electrical separation it is not permissible to connect Temp-S to a
PLC or to a Sensor Module of the SINAMICS drive system.
The drive must always be switched into a no-voltage condition. When handling and
connecting Temp-S, when the drive is switched-on, hazardous voltages can be present at
the terminals on the motor side and at the Temp-S connecting cable.
