Note: 
A  component  power  supply  with  load  will  be  installed  into  final  equipment  which  consists  of  an  electronically  shielded  metal 
enclosure. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify 
EMC Directive on the complete installation again. 
The EMC tests mentioned above are performed using a well defined metal plate to simulate said metal enclosure.   
For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies”.(as available on 
http://www.meanwell.com)”.
