Attention!
The AS-I power supply for the AS-I components must have isolation per IEC 60 742
and be able to handle momentary power interruptions of up to 20 ms. The power sup-
ply for the 24 V supply must also have isolation per IEC 60 742 and be able to handle
momentary power interruptions of up to 20 ms. The maximum output voltage of the
power supply must also be less than 42 V in case of a fault.
