An example given in IEC 61283:
3/N/PE 400/230V 50Hz
or . . .
3/N/PE
400/230V
50Hz
Use of international symbols from IEC 417 is also mentioned.

There are other meanings for this type of notation; typically three-phase
stuff. See IEC60038 where scope is not a component power supply.

Unless the applicable standard says otherwise, yes.
What is the safety issue (injury) that results from non-compliance with the
standard's rules for marking configuration of the input rating?
> Will a ±10%
Yes, that means the product works on the lower voltages and to use it on the
higher voltages you have to move a switch. There is an IEC standard:
IEC 61293
Marking of electrical equipment with ratings
related to electrical supply – Safety

Is something like this allowed?
100-115-120/208-220-230-240
Will a ±10% tolerance always be assumed? If your tolerance was something
different, such as -15%/+10%, does this information have to be on the device or
is the manual good enough?
