I cannot understand the error (not in English) but the error should in essence be telling you what the problem is

Try a different computer, Windows, English preferably (Some of the application does look for English strings)

 

Nothing obvious from the pictures, but the symptoms you describe has a couple main causes, might give you some clues where to look:
- PSU wired wire reversed polarity - tends to damage BlackBox on initial connection, but if it ever was wired incorrect, survived, it can still enter similar shorted state later on when the slightly damaged components from that mistake finally fails
- Other wiring somewhere in the system causing shorts - photos doesn't show other components or wiring for review
- Mains leakage - any chance you have a VFD spindle or Plasma inverter connected?
- 3rd party power supplies: Only ever used the Meanwell, or do you have / had any other PSUs connected to it?

DC GND is connected (GND and +24V are the two wires between the BlackBox and PSU in your pictures, you used Blue to GND)
AC Earth should always be isolated from DC GND - so double check you don't have any interactions between AC and DC domains - those should always be isolated from one another - PSU in between. Could be a surprising source like a endstop mounted wrong passing DC GND to a frame member, and a VFD spindle with mains earth mounted to that same metal structure causing short between AC Earth and DC GND if a short is present

 

The one already damaged will likely continue to stay in that state yes. The question is more of a post-morten - what happened to it, to avoid another suffering the same fate.

Particularly as it happened again. First one you could maybe brush away as a mistake during first wire up, or somehow even a rare one that just gave up the ghost unexpectedly. Two in a row... Solid indication that something is killing them in use.

 

EU/GB/ZA and some others uses Green/yellow as Earth, blue as neutral, brown as live. These countries all have proper 30mA RCD protection at the DB Board too

so his is correct - and on the meanwells incorrect mains wiring unlikely to make an issue on DC side, RCD would trip for an earth swopped with live or neutral, live and neutral swopped will work, though not good practice

 

Same thing essentially, US tends to do GFCI outlets (trips at the wall plug) UK, ZA etc we have a RCD (Residual Current Detector) before all the breakers, so whole building and all plugged in devices are protected. Later regulations puts geysers etc on RCD too, some older regs had fixed fittings like geysers, lights and built in cooking appliances same as US (no RCD, just a overcurrent breaker, relying on a "earth" cable to trip the overcurrent in a fault (full current needed to trip). RCD trips at just 30mA of leakage



Mains switch > RCD > busbar feeding circuit breakers > radial circuits out from there



Any difference over 30mA between live and neutral = trip

Pretty nice actually, hard to mess up

BlackBox does not work with Torch Height Controllers, no. Use a floating head like our OpenBuilds LEAD Plasma uses
