1)
The power supply must comply with the requirements of EN60204 (protective extra-low voltage).
The power supply, signal inputs and signal 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 secured against overloading.
Constant load currents of > 0.15 A can lead to unacceptable heat levels and subsequent destruction of the ejector.
