1)
To meet the requirements of the relevant product standards (e.g., IEC 61496-1), the external voltage sup‐
ply for the devices must be able to bridge a brief mains failure of 20 ms. Power supply units according to
EN 60204-1 fulfill this prerequisite. Suitable power supply units are available as accessories from SICK.
2)
The load currents for the input capacitors are not taken into account.
3)
With a typical supply voltage of 24 V.
4)
Ferrules are not needed.
