4.4.2.2 Series-connected electromechanical sensors
You can connect electromechanical sensors, for example, Emergency Stop command devices,
position switches in series.
If the sensors are simultaneously opened, then sensor faults can only be identified with some
restrictions.
If there is a risk of cross-circuits or short-circuits, the cables between the sensor and the inverter
must be protected, for example, by routing them in a steel tube.
The inverter supplies the power supply voltage
