flat washer on the rear. Fit your ring terminal (or terminals) onto the screw, place another flat
washer and star washer on top of that. Secure tightly with an M4 nut. This should ensure that
the panel is robustly connected to 0V.
An single M4 crimped ring terminal secured to a panel bonding point. A solder tag with a 4mm hole
could also be used but for thicker wires, like this 24/0.2 wire, crimping offers better performance and is
simpler.
An M4 ring terminal crimped to 24/0.2 insulated wire. This sort of connector is suitable for both the panel
ground bonding point and attaching to the dedicated 0V screw terminal on the PSU board.
Personal Note...
One has to a little careful when using the word 'ground'. I sometimes talk about local ground
and 0V as being the same thing. This is technically incorrect but it is used a lot. I worked at
Marconi in the 80s and Soundcraft in the early 90s, and ground and 0V were used
interchangeably even by seasoned engineers. We'd talk about chassis ground, dirty ground,
