Manuals vs certification plates


If a device manual with a stated model reads 220-240V 50/60 Hz must the certifcation tag match?

Is this different on a per country basis? (In this case Germany)

For example this manual excerpt:

this one

Does the device tag need to match exact?

Just as an example of where the manual doesn't appear to match the product label, some switch mode power supplies may be labelled 100 volts to 230 volts but UL testing and CSA testing will be 15% above and below those values and, the manual is quite at liberty to give the fuller range ie 85 volts to 264 volts. I've seen this just recently and had it confirmed by the reputable supplier.
