hello I purchased make noise skiff and modules(rubicon ,dixie 2) modules arrived today when ı plugged modules ı saw smoke coming under dixie and rubicon then ı immediately switched it off. I powered on skiff again and ı saw the skiff lights on. it seems that skiff is working but when ı place the modules there is no sound coming from output of both dixie and rubicon also no lights on. ı will send them back but ı am not sure skiff is working or not is there way to understand trouble by myself.

That was going to be my suggestion, polarity revered. Most manufacturers realize this is an easy mistake, and should have a circuit protection diode and fuse in place. Inspection and replacement of these components could restore your module.

Write an email to Intellijel and see what they say. It might not be trivial, these are not protected against reverse polarity... And IJ are usually helpful, IME.

even if it is user's fault there must be text or symbols on the box that warn the users against electricity problems. it is not cheap 399 usd +tax :( even cheap hair dryers have electricity warnings ,i will consider this reverse polarity feature my next purchasements

On the power supply distribution boards there is usually a keyed socket so the wiring harness cannot be installed wrong. I have no idea why manufacturers don't put these on modules.

Because that's the way Doepfer deisgned the connections and now everyone is stuck with it. When I had my Eurorack all the cabling was clearly marked for proper polarity, it wasn't a problem.

If and when I do a Euro setup, I'm going to get a red Sharpie and viciously mark the end of the power connector where the red stripe goes, on every module.

damn that's a great idea. A little margin of safety goes a long way

Not necessarily a good idea, the red stripe by itself is meaningless - you can (often) invert the ribbon cables. Make sure you plug -12V on the module to -12V on the power socket, and everything should be good.

Also, most manufacturers mark the -12V on the module or put it in the same spot consistently.

Just tripple check everything before you power on.
