I am preparing a large installation with three cabinets around the house. Each cabinet will host 1 power supply (VMBSMPS or VMBTR1/VMB3PS combo).
I know from the docs that all 12V grounds must be connected to establish a reference level.
My question is: can I do this through the bus cable that goes around the house and also will be routed through these three cabinets? Or is it preferred to use a separate ground cable for this purpose.
