1) The power supply must correspond to the regulations in accordance with EN60204 (protected extra-low
voltage). The signal inputs and outputs are all protected against reverse polarity.
2) Plus the output currents
3) The signal output is protected against short circuits. However, the signal output is not protected
against overloading. Constant load currents > 0.15 A may lead to impermissible heating and therefore the
destruction of the ejector.
