if you don't understand how drives work you should not be taking those covers off period... there are capacitors in them that can be live after turning them off. yes you can see if those disconnects are off look at the position of the disconnect, horizontal means off or disconnected.

So yea what you said is true but when most people don’t understand is when you even physically turn the drive off the capacitors on the DC bridge of it are still alive and still have high voltage for up to five minutes sometimes even 10 which is a higher threat most are unaware of

if you have no experience in high voltage and drives and troubleshooting & such this should not be attempted by anyone.this PSA is for people that are aware with how these work and the risk.

and having your disconnect device in a area that can be live....don't really think they would meet regs on disconnect the drive...you have to open circuit before access of fuses

@Diego: Hi Mr Appleton, thanks for the information. I work with them all the time, and I am kind of new to bas and you know it’s way different than pulling power. All the best💪🏼

Using a ticker pen on three phase is crazy work… where is your meter son?

Rule 1 get your meter and test it in a different location. Once verified the meter is working correctly. Is when you may use it to test anything to see if you can touch it. And you did not explain the DC bus. To true danger ⚡️

Well, typically, you cannot open the cabinet door without the main disconnect being off

Surprised you can take the cover off in “ON” position but I guess it’s easy to flick that disconnect with a set of pliers… troubleshooting etc

I miss the point here totally. Its clear one of the disconnect is still on. Now anyone working on such must be qualified. I am here wondering if one of these drive zapped u and are in panic mode.

It’s probably bc ur disconnect switch is on still and the

funny ive never seen a danfoss with ABB isolators. you need to immediately recognise that the actual drive is the top module. where your testing looks like a control box/power filter. 2 seperate panels. 2 seperate isolators. mad your using a volt stick to prove dead though.

isolate and measure with the meter are the first 2 steps bro...

CIS Developments :
So Danfoss is dangerous because someone didn’t turn it off or because they overrode the handle in the on position? I think this applies to electricity in general, nothing to do with Danfoss and more to do with common sense

John Donovan :
This is LOTO 101…. Always verify with the meter 1. Test a live circuit first like a plug. 2. Test the device you’re working on to make sure it’s dead.3. Go back to step one source and verify power again.

bestbloke123 :
I appreciate your warnings, but just a small question? Do those ABB isolators have external handles mounted on the escutcheon covers ? Usually they have a locking mechanism that requires an override pin to remove the cover when not isolated ? Did you remove the covers or is their no isolation handle on the extension shaft ? Thanks again

Ronald Loderus :
LoToTo is solid, but it won’t save you from a charged capacitor. Power off ≠ safe. If you don’t bleed and meter the caps, you’re gambling with your fingers or your life. disconneced doesn’t mean discharged.

the disconnect is on for the 1 on the right. it's verticle. the 1 on the left is horizontal for main power coming in

Søren :
Rule nr 1. Always assume that a installation is under voltage until your measurements show you they are not. First thing you learn at trade schools in Denmark. And first you test your instrument then measure then test again on a known source

They also have capacitors always check voltage

Smallblock :
Always use your multi meter. Hot sticks will let you down. Also if someone is working on it, it should be locked out. Not trying to be that guy but it is truth.

Instantly replace with ABB or Yaskawa

Berwick3806 :
First thing you should do is check your load side terminals of the main switch/isolator. If you took the cover off you should have noticed that the switch was in the ‘on’ position and if you didn’t take the cover off then like I said. Test the load side.

If I seen right the disconnect on the left was off and the disconnect on the right was on.
