Example: Parallel connection with TM120

Application: Four motors connected in parallel

The shown topology requires four KTY sensors and four PTC sensors:

● Each primary section has one KTY sensor (Temp-F) and three series-connected PTC

sensors (Temp-S).

Two TM120s are required:

● A TM120 is interconnected automatically in series between the Motor Module and the SMx

Sensor Module.

● A TM120 is directly inserted into a Line Module: This requires a manual interconnection by

the commissioning engineer.
