1) The power supply must correspond to the regulations in accordance with EN60204 (protected extra-low
voltage). The signal outputs are protected against reverse polarity.
2) Plus the output currents
3) The signal output is protected against short circuits. However, it is not protected against overloading.
Constant load currents of > 0.1 A can lead to impermissible heating and subsequent destruction of the
vacuum switch.
