4.1. Labeling / Marking

The following is a non-inclusive list of suggested markings for each power supply unit. Product regulation stipulations for sale into various geographies may impose additional labeling requirements.

•Manufacturer information: manufacturer’s name, part number, and lot date code, etc., in human-readable text and/or bar code formats

•Nominal AC input operating voltages (100-127 VAC and 200-240 VAC) and current rating certified by all applicable safety agencies (Section 8)

•DC output voltages and current ratings

•Access warning text (“Do not remove this cover. Trained service personnel only. No user serviceable components inside.”) in English, German, Spanish, French, Chinese, and Japanese with universal warning markings

4.2.Physical Dimensions

The supply shall be enclosed and meet the physical outline shown in either Figure 8 or 9, as applicable.
