EURORACK POWER PRIMER AND EXTREMELY NERDY POWER CHECKLIST
Eurorack power is delivered through ribbon cables which must be correctly orientated on both the module end and the power distribution end. The ribbon cables plug into either 10 or 16 pin strips on the products. Many manufacturers put special connectors that use a notch on the ribbon cable ends, to ensure they can only be plugged in one way around, which is helpful IF the ribbon cable has been correctly manufactured. Not all manufacturers use these headers however, especially on the module itself, and there are many inconsistencies between manufacturers. There are NO universally agreed standards, necessarily.
There is a +12V side and a -12V side on each connector. -12V on the power plug should lead, via ribbon cable, to the corresponding -12V end of the pin connector on the module, which is often marked with variations on: ‘-12V, Red, Red!, Red Stripe, “|” and so forth.’
Unfortunately, the responsibility of confirming correct orientation lies with the user.
1. Is the cable made correctly? Cables can be made incorrectly. When you fold the cable over itself and compare the pin connectors with the notches facing in the same direction, is the red/coloured stripe on the same side of the connector on both? This indicates a good cable.
2. Are you actually plugging into a power socket on the module? Some modules have expansion sockets which use the same connector type as a power inlet. These are normally marked, but may not be. Check the manual to be sure, or ask the manufacturer.
3. Now you found the power inlet socket on the module, do you know which side of the pins expects -12V? This is where most mistakes that damage modules get made - it is never wise to unplug the ribbon from a module.
As mentioned, the -12V end of a Eurorack module's power inlet is typically marked with variations on ‘-12V, Red, Red!, Red Stripe, “|” and so forth. CHECK THE MANUAL TO BE SURE, OR CONTACT THE MANUFACTURER _ONLY_.
Typically one would plug the module in so that the Coloured/Red Stripe on the ribbon cable ends up located on the side with the -12V power pins.
BE AWARE THAT NOT ALL MANUFACTURERS NECESSARILY PRODUCE CABLES WHICH ARE DESIGNED FOR THE RED STRIPE TO REPRESENT '-12V' - CWEJMAN LITERALLY DO THE OPPOSITE. IT IS MISLEADING TO ASSUME RED STRIPE ALWAYS INDICATES -12V BECAUSE OF THIS.
Doepfer do not indicate power orientation on many of their modules, nor, inexplicably, do they indicate this in the manual either. But they maintain a design principle that the -12V pin is at the bottom of the module, if the module is held upright. But this 'rule' applies ONLY to Doepfer, and some have horizontal sockets(!) DO NOT APPLY IT TO ANY OTHER MANUFACTURER.
CHECK THE MANUAL TO BE SURE, OR CONTACT THE MANUFACTURER _ONLY_.
4. Is the other end of the ribbon cable plugged into the power output socket on your Eurorack power distribution board/flying bus board the right way around?
You are aiming for -12V on the module to lead to -12V on the power board. The -12V should be marked with text, or a red stripe.
On many distribution boards, shrouded headers are used so that you literally can ONLY plug it in one way round. So it is essential that your ribbon cables be made correctly. JUST DO NOT ASSUME RED STRIPE AUTOMATICALLY MEANS -12V.
When connecting to unshrouded connectors (bare pins, i.e. Doepfer, Intellijel), CHECK WHETHER YOU ALIGNED THE PINS CORRECTLY. It is easy to accidentally plug the power connector in too high or low accidentally, especially when swapping out a module in a dense system. CHECK WITH A TORCH, or feel above and below the ribbon cable with your finger to confirm no pins are floating free!
5. Final check before power on: You should be able to use your finger and trace from the -12V INPUT pin on the power header of the module, through the ribbon wire, to the corresponding -12V OUTPUT on the power supply.
You are aiming for -12V/+12V on the module to lead to -12V/+12V on the power board. Irrespective of red stripes.
If you are in ANY doubt, DON'T CHANCE IT - it's statistically more likely you're going to get it wrong, than right. CHECK THE MANUAL OR ASK THE MANUFACTURER.

    What boggles my mind here is that 10 pin PCB headers for ribbon cables are EVERYWHERE. I've got a box full of them when building my DIY Midi2CV they're really hard to just buy one unit. So I don't get how every manufacturer doesn't just have a box of these in the corner of their factory. Finally it's quite easy to protect the circuit from reverse polarity. Again not doing both is a questionable choice especially for relatively expensive modules!!!

Once you release the smoke electrickery cannot work. End of class.

    Alex, this is God's work you're doing with this video, man. Also, additional note about unshrouded headers: I know all of this, and I STILL killed a module by not literally being able to see well enough by SKIPPING AN ENTIRE ROW OF PINS. Not offsetting, up or down, but side to side. BOOM, spark, smoke - luckily it was a single capacitor that blew (I found a chunk of it in the case later on). The Make Noise boards don't even have pins that go UPWARDS, like the Doepfers; they are parallel to the back of the case, making it even harder to align properly.

    Well I actually hung out with Maho Cwejman herself this weekend and to their credit - she explained the reason they put red as "+" is because in electronics, red always means positive!! In that respect it is more logical than Doepfer. But unfortunately it's the opposite of the more widely-owned-and-traded brand. Bottom line is there are no standards, no 'rules' - the ultimate lesson of the video is 'be aware, be informed, and just triple check everything'. With that said, I do think Doepfer need to put a note about power info in each and every one of their module manuals.

    M Campbellell... problem??? If you supply a correct cable with the product and everybody uses cables of the same standard then the only people with problems will be those who try to use wrongly wired cables and Darwin takes care of those people pretty quickly. The computer industry went through this way back in the 70s. Some people paid attention to it. Apple for instance has been using shrouds in everything since 1979 and as a result during the 80s and 90s, Apple equipment didn't constantly end up in the shop with blown boards because of misaligned connectors like PC hardware did. The same is true for peripherals on all platforms. This isn't rocket science. I completely agree with you about polarity protection. A 2.2 ohm resistor on the rail feeds with reverse biased 1N5408s behind them should be a minimum. There's no reason people can't use polyfuses either.

    Never disconnecting the cable from the module is sound advice, but not always achievable. Sometimes it’s impossible to reach your hand into the back of the case with the cable attached to the module. And sometimes a cable won’t reach at all, so you have to swap it for a longer one. I’ve made a habit of always looking for markings on the PCB before disconnecting, though, and for those like Doepfer without markings, keep a Sharpie handy to make your own.

    Excellent Public Service Video. They should show this on day one of Modular School. I don't think I've ever bought a Doepfer module that wasn't shipped with the cable already attached. Second hand has been a different matter of course. I use Doepfer cases and the buss boards are a nightmare, exactly as you proved. Even when the connector is the right way up, you can go a pin too high. You just can't see what you're doing. Just wait until you're an old fart like me and your eyesight gets crappy. It's terrible. This is the actual reason old guys go 5u... Another Doepfer thing: Older cases with the PSU 2 Linear supply, have no 5v. The newer cases with the PSU 3 do have 5v on the buss boards. Ta!

    So i got the A-148 today (btw they added the word RED on the pcb so u know what way to plug the wire) i plugged it in correctly and it worked fine. But then i turned off my rackbrute and the power supply just didnt turn off. The modules plugged in past it did but I could definitely smell something heating up somewhere. So ive now added “make sure your case turns off normally” to my list of things to do when i get a new module.

    Thanks a lot for the video. I have quite a lot of Doepfer modules and have learned the down is -12v / red stripe trick too. But i have also plugged them the wrong way round and i am lucky enough to have not blown any of the up. I have Doepfer psu3's in home made cases and all the lights on the modules flash on and off if the power connector is the wrong way round and no magic smoke so far i'm not sure if this is a reflection of some kind of protection the psu3's or not? Did you say you replaced the TLO74 and no luck? I have the A-148 as well and you could try replacing the other chips and the only other things i can see that might blow are the two capacitors near the power connector and there's a diode in the middle. Fairly cheap components mostly probably about 5 to 10 pounds? Anyway thanks again for the important video and the amusing intros. Take it easy.

    Dave Smiths Curtis filter module was one that caught me out, once when I was moving modules about it not long after it was fitted correctly was the only module that doesn't have a notched end on it's ribbon connector and I forgot, plugged it in the wrong way, I use row power with flying bus cables as I think they are excellent, seemed to damage only the row power I had, the 5 volt light is out (I don't use it although it seems still work, probably not for 5 volt though). I always read the manuals and check when getting a new module, just for my own paranoid connection sanity.

    Also wondering what you think about preventing fire risks in the studio and what to do if one does occur, like what type of extinguisher won't ruin adjacent gear while still being effective. I've also heard that lead-free solder can lead to fires because it grows dendrites over time that can cause short circuits. You never really know if there was repair on used gear done with this kind of solder. There have been quite a few studios burn down but I'm not sure what the common element has been.

    Also wondering what happens when CV is plugged into audio, audio into CV. I've heard that the results differ between modules from nothing to destruction. There are so many modules that don't label in's and out's, some just print funny symbols on their panels and expect you to figure it out. Once you start messing with things like 5 way cable splitters partially connected to other 5 way cable splitters I can imagine it gets to be a lot to keep track of to make sure you don't destroy 10 modules with 1 dumb cable mistake.

    Another idea that might be helpful is to make your own cables. You build your own system anyway, so why not the cables. That way, you can also make cables just as long as they need to be, which saves a lot of space and avoids spaghetti behind the modules. It probably has some electrical benefits on top of that. Here is what I do: 1. Shrouded connector busboards only. Those will ensure you plug the cable in a consistent, right way. 2. Normal grey cables with red stripe for "standard" modules (shrouded connectors, clearly labeled pin layout etc). Red stripe indicates -12V and is (just) and optical aid. Don´t forget to finger trace when plugging in. For my setup, this would the vast majority of modules. 3. Different color cables (rainbow colors) for any modules that can be tricky. Tricky means: No standard pin layout or orientation, bare connector without shroud, missing clear labeling of the -12V pins etc. This way, they stick out and will flag connections for extra attention. You will plug cables out of modules at some point in time, so this is a reminder to check carefully. Don´t forget to finger trace TWICE when plugging in. A set of 30m cable plus connectors and crimp tool costs less than your average module and will give you a) peace of mind and b) neat cabling for better access to the space behind modules.
