Couple of basic questions regarding power supplies

Hi - I'm going to be using a Bias Power BPS-200-2-14-50:

in an upcoming project. I have a couple very simple questions though:

It has an "EM" pin, and for it's description it just says "see emi app note". This app note is no longer available. I did find an archived version of the website that refers to the EM pin here:

it says "for connection of external Y capacitors to reduce EMI in certain applications". Can somebody tell me what Y capacitors are? Or if this is even needed?

Also - this power supply will be powering an RF circuit. I am wondering - should I connect earth ground to the ground pin on the power supply? I'm very unsure about this, and figure it's most safe to ask first.

Thanks,

-Michael J. Noone

Hi Mr. Fields - Just to clarify - do you think that they are saying to connect a Y capacitor between the EM pin and earth ground? Also - in what sorts of situations is this needed? This device will be running inside off of wall power - would such a capacitor be needed? I'm thinking probabaly not, but I thought it best to ask to be sure.

Thanks,

Michael
