No direct connection of the temperature monitoring circuits
Risk of electric shock when incorrectly connecting the temperature monitoring circuit
In the case of a fault, circuits Temp-S and Temp-F do not provide safe electrical separation
with respect to the power components.
• Use, for example, the TM120 or the SME12x to connect the Temp-S and Temp-F
Correctly connecting temperature sensors
NOTICE
Motor destroyed as a result of overtemperature
The motor can be destroyed as a result of overtemperature if you do not correctly connect
the temperature sensors.
• When connecting temperature sensor cables with open conductor ends, adhere to the

Technical features of temperature sensors
Technical features of PTC temperature sensors
Every PTC temperature has a "quasi-switching" characteristic. The resistance suddenly
increases in the vicinity of the response threshold (nominal response temperature ϑ
PTC temperature sensors have a low thermal capacity – and have good thermal contact with
the motor winding. As a consequence, the temperature sensors and the system quickly
respond to inadmissibly high motor winding temperatures.
