Wiring
- On the power supply, why is V- connected to GND?
- Internally, these power supplies do not electrically connect V- to GND. This is for added flexibility from the manufacturer in cases where you might want to stack power supplies to create higher voltages. First off, note that in our situation, the frame is connected to GND. We want V- to be connected to GND such that any detached live wires that contact any metal surfaces short to GND and blow a fuse, disabling the machine but not destroying any other electronics other than the fuse.
