MK3.5 with meanwell power supply

Hi Folks, has anyone upgraded their mk3s+ to mk3.5 that has a meanwell lrs 350 power supply? Looks like the wiring is a bit different in relation to power panic and the additional earth wire. Just wondering if anyone had issues.

I've got a MW LRS350, from your PE cable perspective you will need to attach the PE cable to earth-ground: 

The big thing is preserving power panic. If you do not have the power panic board then you do not need to worry, but if you do, you will need to change the soldered cable out for the new one, as the new control board has a new type of connector.

Thanks Jonathan, the attached pic is my current setup. I've power panic fed from the spare 24v output on the power supply. It looks like I might not need to do anything other than add the additional grounding wite  to the out side of the power supply.

Did this work for you?  Did you get a chance to test if the power panic worked?  I'm about to do the MK3S to MK3.5 upgrade (and have the Meanwell PSU from like four years ago) and want to make sure I don't blow anything up, as I'm not very knowledgeable with electronics.
