If using an external DC wallwart style psu would the 0v line still get tied to the chassis as the common ‘star’ point? Obviously if it was mains level voltage then the safety earth would be connected to the chassis for safety reasons.
I’m looking at making a project using the following PSU and usually I would use a mains toroidal in the box etc hence linking in the safety earth but using an external one is new to me.
