Controlling several inverters in parallel using electromechanical sensors

You may activate the safety functions of several inverters simultaneously with one or several
series-connected safety sensors.
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
