Re: How to mark the power rating and describe in the CB report?:


Hi, Group,
I have aquestion. When one equipment have two power input which one can 
power for the equipment and one is only for backup, how to mark the power 
rating?  
Is rating label required for the whole equipment? if yes, how to mark the 
power rating in the label in this case?

Your message was not fully received, but I think the answer to your 
questions can be found in EN 60950; look in the index under "multiple 
power sources". 
Since each power input could supply the full input requirements, they 
would each need identical ratings labels. Note, however, that EN 60950 
requires a prominent warning label to indicate to service / maintenance 
personnel regarding the removal of ALL power from the unit (section 
3.4.11). We use one label per input where these are not adjacent on the unit.
Regards,
Neil Helsby
