This brings back memories of the failure of a large UPS at a datacenter where I used to work. The cause of the damage was, again, water entry, due to a failure of an A/C unit nearby. Eaton sent a tech out to repair the unit. Less than 5 minutes later all the lights dimmed in the call center. Then we saw the Eaton tech being carried out to an ambulance. As I understand it, he failed to check or disconnect a voltage source and got severe burns. The Eaton tech recovered, but we had an object lesson in properly paying attention to safety precautions. Shortly afterward, the people who managed the datacenter implemented stringent "lock out/Tag out" standards.
14:46 BP Voltage out of range" refers to Bypass Voltage out of range in Eaton UPS systems, which occurs when there’s no AC power connected. By default, the UPS only starts when main power is present. You can bypass this by holding down the power button after the UPS initially turns on, allowing it to start without wall power or a phase. There is also a setting in the UPS to enable startup on battery power. As a side note, if you start the UPS without grid power, it will have a random phase direction. If you later connect it to wall power, the UPS will sync with the grid within a ±0.5Hz range, which is another configurable setting.
Wow, that is a horribly confusing error name. How did they not realize people would misinterpret that as "Battery Pack Voltage"?? Why the hell do people do two letter acronyms for a single word like that???
@@tbuk8350 its stupid, but CS and their technicians ideally would know what it means when it matters, like if it was already plugged into ac power. would still be better to make it clearer and save a google search or the poor CS reps from telling people to plug it in
This is definitely one of those cases where swapping out your LTT driver for a good set of electrical screwdrivers that have an insulated handle is worthwhile, especially if you’re going to point at stuff with the screwdriver.
Even if the design includes a bleed down resistor, when you are dealing with damaged components, you cannot rely on the bleed down resistors still functioning.
The design MUST include bleed down resistors if its is to be sold in north america, it needs ANSI and or CSA, or a ULC standard approved by the US or Canada
The only way that would happen is if the connection between the capacitors and the bleed resistor broke somehow, which is highly unlikely. It will protect you from 99.9% but always have a healthy fear from high voltage capacitors. It's charged until you confirmed it's not by measuring and/or even attaching your own bleed resistor onto it.
I've seen a high voltage electrician get completely vaporized in pursuit of a dumb joke. Knowledge doesn't necessarily prevent incidents from negligence. But it does make it funnier.
To be fair 240V across your tongue isn't going to kill you - but you'll definitely feel it. Needs a path across your heart to even begin to be dangerous, and even then 240V is very unlikely to stop the heart of a young healthy person. I'm not saying you shouldn't be careful, but it isn't like he was on the edge of a cliff there or anything.

This was a super fun video! Tyler was fun to see on camera and it was interesting to see this kind of project, saving something that was supposed to be dead :D
Ya'll should do a video on how to set up a UPS for home use. I know there are tons of affordable units that are essentially plug and play, but I could totally watch a video where you outline how to properly speck a UPS based on your needs (how much do you have plugged into it, how long do you need it to run, is this just to clean up dirty power, etc.), if it makes sense to buy a second hand unit, and what different battery options there are out there.
Not wasting money goes two ways. Repairing good stuff instead of trashing it is one. Not buying trash is another. For many people whom can turn a penny into copper wire between their fingers, long term cost analysis (while taking service life and quality into account) often leads to a more expensive purchase over a less expensive one.
I'm an hourly paid electrician. I built my 1969 nova ss clone from the ground up in a dirt floor shop. I have about 30k in it and it is appraised for 60k. You can like nice things and be cheap. I still buy great value brand and eat ramen noodles. I can promise ya the 6.0 LS in my nova throws a code I can fix it before the weekend is over. Linus is gonna take that Porsche to a dealer and pay out the ass while waiting months.
At this rate we're going to get a full suite of... "My home server rack filld with my computers all DROWNED!" "My computer rack caught on fire, it OVERLOADED!" Honestly linus at this point you might aswell dunk the whole rack in a big mineral oil tank.
3:30 Coincidentally I also fixed one of these just the other day (it had been stored in a humid environment and had some corroded PCB traces). These Eaton 9PX do **NOT** discharge the capacitors when powered off. I was still measuring 280V on the big electrolytic caps 24 hours after it had been turned off and unplugged (both mains and battery).
Great work stepping through the diagnostics and coming up with a successful and cost-saving solution. It's impressive how you tackled the issue instead of just opting for a new unit.
13:34 those fuses aren't directional, that symbol means that they are high speed fuses (or semiconductor fuses) meant to protect semiconductor components, but they can still be mounted either way.
That is exactly right. And at least here in Europe (well, at least in the German speaking part of Europe, not sure abeut the rest) they most of the time also have the sign "gS" beside the diode sign stamped on them. They both mean the same. As far I know gS stands for the two German words Geräteschutz Superflink what means device protection and superfast. We used such fuses to protect drives for motors with up to 120kW.
This is the reason that if you're gonna go with liquid cooling you should use mineral oil, not water. Mineral oil is nonconductive and most things won't dissolve in it meaning if you have a good enough filter to catch the metal particulates from the pump, a leaking cooling system filled with mineral oil won't cause nearly as many problems as one filled with water.
This guy helping you out is so good. I find him really funny and entertaining and it feels like he knows what he is doing. I would LOVE to see more of him in the future❤
Couple of things worthy of note for capacitors: Just because they are rated for say 600 volts doesn’t mean that they ever had 600 volts on them. Second of all, if there’s bleeder resistors on the board before touching anything short across the traces for the capacitors with something like a screwdriver. As soon as you do that you’ll be safe because the bleeder resistors will prevent those capacitors from charging up again. For the people who aren’t electrical engineers, capacitors can charge to a significant voltage if you don’t have a load on them, they are able to do that by picking up charged particles in the air and slowly building up a charge. That is why you always leave high voltage capacitors shorted out when they aren’t in use.
Big capacitors are scary things indeed! I have a couple personally that require the Permanently shorted procedure! Edit: permanently shorting large capacitors is for storage if they are not in a circuit
Indeed. Film caps dont really come in low voltage ratings. It is common for even a very small metalized polypropylene signal cap in audio to be rated at 250-600V
This is my favorite type of LTT video. I like watching things be repaired, ideally like this video where you have a pro and an interested hobbyist to bounce off each other.
While lithium ion would not be the route to go, lithium iron phosphate (LiFePO4) would be a much better choice than lead acid while also being much safer than lithium ion. It lasts a lot longer than lead acid, you get the full usable capacity out of it compared to 50% out of lead acid, and it doesn't go up in flames like lithium ion can.
Although Eaton still call it 'Lithium ion'. (And technically, it still uses Lithium ions to do it's thing). And all this confusion is made worse by ion and iron sounding the same.
@@phuzz00 You could call it a "Ferrous Lithuim battery" and keep it distinct; but I feel like a some people wouldn't quite know that ferrous means iron.
All the warning saying "DO NOT TRY THIS AT HOME" is good advice for everyone except me, Im a carrier electrician and an electrical hobbyist so i guess ill drop it since linus said not to
The best thing about this is the fact that rather than get rid of the old water-damaged one, you salvaged what you could, and took another one that was damaged, and made one that's working - which means less waste that needs to be recycled, in addition to the monetary savings. Less waste and less spending means better for everyone.
I absolutely love the message of REUSE first (because let's be fair: this IS reuse, not repair). Most fixes that end up working like this, tend to be about as easy. If you need to actually _repair_ something (not just swapping it out for a "similar" thing and hoping for the best), the chances of it working go down sharply unless you actually know what you're doing. But the good news is, people get rid of stuff not because it can't be fixed, but because _they can't be bothered to deal with it._ But remember that an hour of your time isn't "free" either - it sometimes makes sense to actually pay the money (if you normally sell an hour of your time at $35, ordering a broken $30 thing and then spending 2 hours to fix it, that's $100... maybe that $80 part is worth it ;P).
I love these types of videos as a person that works with repairing "electronics". The text tips that come up are perfect for getting info and not being intrusive
Good work Linus and Team for improving the safety consciousness of your videos. This was very well done and did a good job visually of communicating to the viewer that this is dangerous and to be safe with electricity.
I've got a pile of old UPS units to salvage and see how many I can get working. At least those are only 12-24v. After watching so much BigClive, it's nice to see a high-power board actually designed well 😅 This is solidly in the "if you're asking, the answer is no" category of DIY stuff though. Those caps are terrifying. To quote Styropyro, not only will they will kill you, but it will hurt the whole time you're dying. And then it might kill the person who finds you, too.

Indeed. Film caps dont really come in low voltage ratings. It is common for even a very small metalized polypropylene signal cap in audio to be rated at 250-600V
I'm sorry Mr. Sebastan. We are denying your house fire claim. We watched a video of you clearly wiring a 240v wire... onto another 240v wire.
1:20 finally, a Segue I not only didn’t skip, but watched *twice!* #livelaughliao
0:45 damn that porsche
It's not the Tycan - it must be in the shop
I missed it at first! Good eye
yeah, no wonder why he needs to rebuild equipment and save money, lol
Jerry: Glass is glass
Linus: Metal is metal
Apollo the bird: _Shrok_
I have never struggled so hard to understand "Hennessy Velociraptor".
It's very straight forward
I have not understood a single word in those segways 😅and I am used to the Vancouver Accent 😂
I absolutely love Dennis's Commercials/sponsorship videos. Please, keep more coming!
Tynan is having so much fun, you can tell he loves what he does!!!
I feel like the no beard orange hair is part of another elaborate A/B test. Some people get beardy Linus and we get this
Feeeeeel?
And thus Linus' home insurance policy was cancelled once they discovered the second hand UPS installed in the basement.
You say that as a joke, but that's a serious possibility!
@@coccoborg The way my luck runs it would 100% happen to me.
1:24 wtf did he even say😂
I heard Velocirouter 😅
Sweetsteaks for a Hennessy Veloserouter
I mean, the one at 18:01 sounded like Vlassic Router..... didn't know a pickle company got into tech.
This is my favorite type of LTT video. I like watching things be repaired, ideally like this video where you have a pro and an interested hobbyist to bounce off each other.
The looks of excitement on Tynan's face whenever he points out a big capacitor tell me that I want no part of any of this 😂
If ever Linus dies, I think Dbrand would sponsor the casket.
They discussed this on the WAN at Computex - it's on LMG Clips.
@@random27 it's been discussed on the Wan Show🤣
While lithium ion would not be the route to go, lithium iron phosphate (LiFePO4) would be a much better choice than lead acid while also being much safer than lithium ion. It lasts a lot longer than lead acid, you get the full usable capacity out of it compared to 50% out of lead acid, and it doesn't go up in flames like lithium ion can.
Eaton's Lithium UPS' use LiFePO4
Although Eaton still call it 'Lithium ion'. (And technically, it still uses Lithium ions to do it's thing). And all this confusion is made worse by ion and iron sounding the same.
@@phuzz00 You could call it a "Ferrous Lithuim battery" and keep it distinct; but I feel like a some people wouldn't quite know that ferrous means iron.
People risk their lives at work everyday for 22$ an hour. 5000 is worth the risk for most people
Thats how Taylor Swift gets new boyfriends.
People risk their lives constantly checking their phones while driving lmao.
@codyBarnette-GNARK *$22 not 22$... 🤦🏾♂️
@@facelessfaceman9716 bruh why do you care it's a comment under a video not a accounting report
I jumped into a 7' hole without shoring. Dumbest thing I have ever done for $26/hrs.
I love seeing stuff like this! Tynan seems super knowledgeable and would love to see more videos with him.
NGL this is one of the best videos in a while really really happy to see Linus just having fun again.
0:47 Can't help but notice a Cayenne randomly chilling in Linus' garage
Good catch! That's the "courtesy car" he gets every time the Tycanne is in the shop, I think.
@@Metal_Maxine Or perhaps, the "gaming minivan" was replaced by a new car
Ah, so the Taycan is broken again, isn't it?
@@Fabri91 it never left the shop lol
@@Metal_Maxine thats the old model, they usually give the latest model of the curtesy car
We need Linus battery tasting
I miss Waterjet Channel's Mitchel lick test
"Not to your taste?" Dennis ads are the best lmao
I enjoyed that video. But even more I enjoyed the Ridge ad. Dennis is something else XD
All the warning saying "DO NOT TRY THIS AT HOME" is good advice for everyone except me, Im a carrier electrician and an electrical hobbyist so i guess ill drop it since linus said not to
Tynan wiggled like a cat whilst watching the UPS.
Tynan is my favorite LTT person
Dennis's ad breaks are always fun.
I swear Dennis is the best comic relief on this channel
@0:40 Fitting the theme of the video, solid choice for that solvable placement XD
"AC can't exist when everything is unplugged" that is so sad.
2:18 I'm gonna do it outside then!
Tynan is legit the hottest member of LTT, and the engineering knowledge only makes him hotter
The best thing about this is the fact that rather than get rid of the old water-damaged one, you salvaged what you could, and took another one that was damaged, and made one that's working - which means less waste that needs to be recycled, in addition to the monetary savings. Less waste and less spending means better for everyone.
I absolutely love the message of REUSE first (because let's be fair: this IS reuse, not repair). Most fixes that end up working like this, tend to be about as easy. If you need to actually _repair_ something (not just swapping it out for a "similar" thing and hoping for the best), the chances of it working go down sharply unless you actually know what you're doing. But the good news is, people get rid of stuff not because it can't be fixed, but because _they can't be bothered to deal with it._ But remember that an hour of your time isn't "free" either - it sometimes makes sense to actually pay the money (if you normally sell an hour of your time at $35, ordering a broken $30 thing and then spending 2 hours to fix it, that's $100... maybe that $80 part is worth it ;P).
As a former Aviation Electronics tech for USN, Thats just a weekday hobby:) Currently tinkering with wave guides and microwaves.
Hey Tynan, sweet RescueTool! 😎
Always fun to remember just how tiny Linus is, when he stands next to actual fully grown mans like Tynan.
18:35 I never thought I'd see LTT get pulled over by my state's Highway Patrol lol
I love these types of videos as a person that works with repairing "electronics". The text tips that come up are perfect for getting info and not being intrusive
08:57 9 ways beer and UPSs are alike:
Redundancy: Make sure you have backup.
I can get behind that!
When Linus's water cooling leaks: No damage
When my water cooling leaks: 5k loss
17:55 😂 that was a jumpscare
Good work Linus and Team for improving the safety consciousness of your videos. This was very well done and did a good job visually of communicating to the viewer that this is dangerous and to be safe with electricity.
I've got a pile of old UPS units to salvage and see how many I can get working. At least those are only 12-24v.
After watching so much BigClive, it's nice to see a high-power board actually designed well 😅
This is solidly in the "if you're asking, the answer is no" category of DIY stuff though. Those caps are terrifying. To quote Styropyro, not only will they will kill you, but it will hurt the whole time you're dying. And then it might kill the person who finds you, too.
