Hello, I am waiting for my Zephyr to arrive within the next day or two and have a question with regard to "grounding" the unit so I don't get an electrical schock if something goes bad. I have read the manual on line at the Digitrax site but I couldn't locate any reference to this subject. If anyone in the group is using the Zephyr, I would appreciate hearing if and how you grounded the unit. I will be installing GFI sockets between the power switches and the first outlets in each circuit but since I have easy access to the grounding rod where the electric coming into the house is grounded would like to use that as well. Thank you.
