X42 Terminal Strip - Siemens Sinamics S120 Manual

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.
Note
The temperature sensor connection can be used for motors that are equipped with a KTY84-
1C130, PT100, PT1000 or PTC measuring sensor in the stator windings.
Note
Connection to terminal strip -X9
A cable harness is used to connect terminals -X41:1 and -X41:2 to terminals -X9:8 and
-X9:7.

Connection options of terminal strip X42
The terminal strip is not intended to supply other 24 VDC loads (for example, for supplying
other components on the plant/system side), as the voltage supply of the Control Interface
Module could also be overloaded and result in malfunctions.
