Thanks for your reply!
Yeah it looks like I'm just going to contact Mean Well or someone, as not all data sheets list the earth connection, turns out I'm looking for a grounding configuration of E1. I have found most of my laptop power supplies are grounded in this way.
I know its normally better, however in my particular case it helps.
I am making a photometer using TI DDC112. If I am not using an integration time of multiples of 16.66 ms (because of the 60 Hz mains, long story) I see a sine wave in my measurement at extremely low levels. however, I have found attaching earth ground minimizes this. I have tried filtering to no avail, so, I'm just attaching earth ground as its the easiest fix.
