Method 2, making sure the label for multiple supplies is adhered near each input. For the AC/DC question, if the DC unit can't take AC, the DC unit cannot be labeled AC/DC, and vise-versa. You absolutely must label them differently. The ratings labels can be on separate labels from the model label. The CB Scheme report should be able to describe both ratings in an OR statement.

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? Method 1: mark the power input rating（“ 100-240VAC;5A;50/60Hz”）near each power input and describe “ 100-240VAC;5A;50/60Hz ×2” in the CB report. Method 2: mark the power input rating（“ 100-240VAC;5A;50/60Hz”）near each power input and describe “ 100-240VAC;5A;50/60Hz ” in the CB report. Method 3: mark the power input rating（“ 100-240VAC;5A;50/60Hz”）near each power input and describe “ 100-240VAC;10A;50/60Hz ” in the CB report what method is correct? Is rating label required for the whole equipment? if yes, how to mark the power rating in the label in this case? If this equipment can be powered by DC (if the built-in power supply is AC/DC the equipment is AC type, if the built-in power supply is DC/DC the equipment is DC type), do you think different label is required for AC type and DC type? Can I use only one label and don’t reflect the information of power input in this label, the information of power input is only near each power input? can I describe “100-240VAC;5A;50/60Hz ×2 or -48--60VDC;2A ×2” in the CB report?
