Type: Screw terminal 1 (Page 755)
Max. cross-section that can be connected: 1.5 mm
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, the temperature output of the Active Interface
Module must be connected at terminals X21.1 and X21.2.
Terminals X21.3 and X21.4
Danger to life when live parts are touched when terminals X21.3 and X21.4 are connected
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. 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.
Death or serious injury can result when live parts are touched.
• Neutralize the voltage in the DC link.
