X42 Terminal Strip - Siemens SINAMICS S120 Equipment 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
Function of the EP terminals
The function of the EP terminals for pulse inhibit is only available if the "Safety Integrated
Basic Functions via onboard terminals" is enabled in the software.

Note
Connection options for terminal strip X42
The terminal strip is not intended to be freely used for other 24 V DC loads (for example for
supplying additional line-side components), as the voltage supply of the Control Interface
Module could also be overloaded and operating capability could thus be compromised.
