Type: Screw terminal 1 (Page 730)
The temperature sensor type and the temperature output can be selected by parameter (see the SINAMICS S120/S150

List Manual).
Temperatures are detected but not evaluated in the Active Line Module.

Terminals X21.1 and X21.2
When using an Active Interface Module, its temperature output must be connected at
terminals X21.1 and X21.2.
Terminals X21.3 and X21.4
For operation, the 24 V DC voltage must be connected to terminal X21.3 and ground to
terminal X21.4.
Pulse cancellation is activated if the power supply is disconnected. As a consequence,
regenerative feedback is deactivated and the bypass relay drops out. If the Line Module is
not disconnected from the line supply when the EP terminal is de-energized, for example,
because a line contactor is not installed, then the DC link remains charged.
NOTICE
Damage to the drive electronics when switching the line contactor under load
When switching the line contactor (type according to the recommended selection) under
load, then the contacts will be subject to premature wear. This can cause the contactor to
malfunction, with subsequent damage to the drive electronics.
• Use a leading opening auxiliary contact or use a Voltage Sensing Module (VSM10).
• If this is not possible, then avoid switching the line contactor under load.

If an Active Interface Module is used, the temperature
input must be connected to the Active Interface Module
sensor (bimetallic switch with NC contact).
