4.4 Disabling the Vdc-max controller

Integration of the thermostatic switch as release for switch-off via OFF2
The thermostatic switch must be connected to a free digital input of the SINAMICS G130 so
that the converter is safely disconnected from the power supply if the braking resistor
overheats. A digital input on the TM31 Terminal Module, on the TB30 Terminal Board or on
the Control Unit can be used for this.
Subsequently the digital input must be used as release for a switch-off with OFF2. External
fault 2). The interconnection can be made with the STARTER or via the AOP30.
