I've read through the AUSChristmas 101 manual and I see that it mentions sharing the DC ground when using two power supplies. Is this the case even when I'm connecting to a controller like a Pixlite 16 on two different banks? For reference I'm using two of these http://www.holidaycoro.com/350w-Dual-Output-Power-Supply-p/49.htm?CartID=14. Do I still need to share the ground or V- between the two? I understand that if I'm doing any injecting from either of these power supplies as well that I should be using the same one that is powering the bank the string is originating from. I'm also a bit confused on one more part. I know there are 3 conductors on the AC side - Neutral, Line and Ground. On the DC side there is only V+ and V-. I see in the 101 manual that the V- is referred to as ground. Are V- and Ground the same? How does Neutral relate to these? Or rather how do V-, Neutral and Ground all relate? Sorry for the million questions I've also attached a photo of a power supply I purchased awhile back, I forgot from who, but it came with a Loop between the AC ground and the V- side of the power supply. Do I need to be doing this as well? I couldn't find any reference to it anywhere in the 101 manual or online. Thanks for your help!
