I am working on a bipolar power supply for hobby and educational purposes. Concerning the schematic, is it possible/good practice to place devices that don't go on the PCB in the schematic?
Specifically, I have chassis mounted connectors, TRS and XLR, along with a chassis mounted transformer. Should/Can these be shown on the schematic without generating nets for their connections? The transformer primary, power inlet connector, and fuse are all point-to-point wired, with only the transformer secondary entering the PCB. Should these point to point connections be shown?
If its of any importance, I'm using Proteus 8.
