1 ) The limit values for the voltage supply must not be overranged or
underranged.
The external voltage supply of the devices must bridge a momentary power
failure lasting 20 ms (to EN 60204). Suitable power supply units are available
from SICK as accessories (Siemens series 6 EP 1).
2
) The circuits to be connected to the inputs and outputs must have the
clearance and creepage distances specified in the relevant standards to
ensure reliable isolation to PELV (EN 60204, 6.4).
