No functional reason unless they mount other stuff in the same generic cabinet/chassis and could not fit all the additional ground leads on a single post?

Yes maybe so that other models may have different configuration. I emailed the company and they would not send me a schematic. I would like to know what that weird ground symbol is about

Here is a link to info I found on the dirrerence between a standard earth safety ground and a noiseless ground. In any case it appears that the symbol is not used properly in this isolation unit as both grounds are common.

Thank Tom
I found the article very interesting since I was going to try circuit 2 and isolate equipment ground from house ground. I have done this before but found that it is against code to have two separate grounds and if one chooses to have multiple grounds they must be bonded.

I am finishing up my build but I have a question.
Pictures are a couple devices that are in series with the primary Load and Neutral
I first thought they were MOV but I thought MOV go accross between N and L
anyway here is the pic:

These are NTC (negative temperature coefficient) thermistors. They limit the inrush current that can occur when you first power on a piece of equipment.
Here are a couple of links from the manufacturer of these parts that explains their properties and how they protect transformers.

Thanks for the info guys. I was hoping to determine that those device could be left out.
I just want the Felix filter on the mains side and duplex sockets on the load side
