Hi, I'm an EE at a small company and I have to figure out the regulatory issues on my own so apologies for rudimentary nature of my question... Or product is a telcom industry product designed that will be located in "back room" type application. It is chassis based (metal) and I have selected a chassis mount, metal case AC-DC power supply that will be mounted inside the chassis. The rub here is that the inside of the chassis will be customer accessible (customer is sys admin type personnel) for routine/necessary product configuration. The chassis is accessed via 2 thumbscrews that allow a panel to swing open at which point the AC terminals on the power supply will be exposed. An example of the power supply is - http://www.v-infinity.com/adtemplate.asp?invky=1008007&catky=764537&subcatky1=46887&subcatky2=809398&subcatky3= which has ring terminal connections. To pass UL, I'm guessing that additional shielding will be required to cover the ring terminals. Are there detailed requirements for this type of situation or is any reasonable cover/shield acceptable? Thanks, Alex
