7.4.1 General data
The total current of the nominal input currents I
DC
to be provided by the power supply
module must be determined. If required, the DC cables must be dimensioned in
accordance with the total current.

7.4.2 DC−supply power
The parameters relevant for the selection of a supply unit with a suitable supply power
(even in the overload range) are listed in the below table:

Cycles other than the above cycles must not exceed the specified power and time values,
i.e. the values must be used as maximum values.
The values depend on the rated AC voltage U
