(1) To meet the requirements of the relevant product standards (for example, EN 61496-1), the external voltage supply for the
device must be able to bridge a brief mains failure of 20 ms. Power supplies according to EN 60204-1 satisfy this requirement.
Suitable power supplies are available as accessories from Rockwell Automation.
(2) Operation only in a short-circuit protected system with max. 8 A
(3) The absolute voltage level must not drop below the specified minimum voltage.
(4) The load currents for the input capacitors are not considered.
(5) With the typical supply voltage of 24V.
