NOTICE
Damage when using a non-specified temperature sensor
If sensors other than those specified are connected, this may result in incorrect measured
values. Damage can result if overheating is not detected.
• Only connect temperature sensors that have been specified for operation with a TM120
NOTICE
Overheating of the motor through jumpering the temperature sensor connections
Jumpering of the temperature sensor connections "+ temp" and "- temp" results in incorrect
measurement results. Damage to the motor can result if the overheating is not detected.
• When using several temperature sensors, separately connect the individual sensors to
The table below shows the preferable assignment of the connecting terminal for the
temperature sensor input:

The interconnection provided is a suggestion (software default setting). Which temperature
sensor is connected to which input can be freely configured.
NOTICE
Damage to motor in the event of incorrectly connected KTY temperature sensor
If a KTY temperature sensor is connected with incorrect polarity, it is not possible to detect
when the motor overheats. Overheating can cause damage to the motor.
• Connect a KTY temperature sensor with the correct polarity.
