Note
For protective separation, it is not permissible to connect Temp–F at
the encoder connector X411/X412 of the SIMODRIVE power module
without using a suitable protective module.
When handling and connecting Temp–F, it must be assumed, that
when the drive is powered up, there are hazardous voltages at the
terminals on the motor side and at the Temp–F connecting cable – this
means that the drive must always be disconnected so that it is ensured
that it really is in a no–voltage condition.
he overtemperature shutdown circuit Temp–S has an NC contact for
T
each motor phase winding. The NC contacts are connected in series.

The series resistor is required in the sensor circuit due to the short–cir-
cuit detection function which is integrated in the 3RN1013–1BW10
thermistor motor protection device. Several Temp–S circuits can be
connected in series for each 3RN1013–1BW10 thermistor motor de-
vice. However, only one series resistor should be used for each

Temperature shutdown circuit comprising PTC temperature sensors
(PTC elements).
There is one PTC temperature sensor (PTC element) in each of the
three phase windings (U, V and W). The PTC elements are connected
in series. The characteristics of the PTC elements are in compliance
with DIN VDE 0660 Part 303, DIN 44081 and DIN 44082.
