Can I use x-sim for any RS485 compatible actuator?

All metalwork requires to be bonded to earth, don't rely on ball / universal joints to provide an earth path.

The same applies for metal cockpits that use DC motors... I have seen some around this forum that were leaking current from the USB/or Serial ports to the motor h-bridges and then to the frame... You grab the frame and you get shocked...

230 / 240 volt can kill you. and the 3 phase at 380 / 414 volt will if you get it wrong, if you don't know what you are doing get a qualified electrician to check it over. The higher the voltage the greater the current, and you only need a small current to kill you.

Of course its necessary to have a professionals opinion or help connecting that kind of equipment, if you don't have relative expierence. And always use fuses (20A-30A) between the inverters and the wall plug to save your house power cables in the walls catch fire in case of short circuit or overload.

3 phase motors / voltages are not meant for domestic use, you need to pay attention to cable size and length and not use extension leads.

3 phase motors 220v are already being used in domestic applications more than you think, Dryer/Washer, pool water pump... is some of these examples. With some precautions they are not more dangerous than DC motors.

Hi

AC or DC motors it does not matter, its the voltage that's the danger, dc motors simmers use tend to be 12 or 24 volt. a short might not do the electronics any good but its not lethal to us.

Fuses will not prevent you receiving a fatal shock, all metal frames require a seperate earth bonding wire, not relying on the motor earth, then bolted to the frame, paint is a good insulator. also the top platform would require a seperate bonding wire,

Imagine the frame is not bonded, a cable gets pinched to the frame, the frame becomes live, nothing happens till you touch the frame!!

Also the use of long extension leads / multiplugs increases the impedance of the earth conductor, so to long a lead and even fuses wont trip because of volt drop in the cables.

The mains voltage systems can be made safe, but people need to be aware of the dangers, All the pictures I have seen of AC mains systems, I did not see any bonding cables, also the cables should have mechanical protection and be permanently fixed.

Just my thoughts not having a go at anyone

With regard to single & 3 phase supplies, in the uk 240 volt single phase is the norm, with 30 milliamp earth leakage breakers to prevent the danger of electric shock.

I believe some countries that are 110 volt have some individual 2 phase sockets for cookers driers etc, anyway 3 phase equipment would be enclosed in the appliance or require installation by a electrician.

Hey guys!
What was the thread originally about?
You obviously haven't noticed the author hasn't replied.
You lot have gone way off topic.
Granted its very interesting info here though.

It was about RS485 actuators, which most VFD inverters fall under this category!!!! ... So?? Its better to have a good conversation about it and share some good ideas instead closing up yourself in your cell...

No worries, I was just concerned this was getting off topic.

I will crawl back into my cell

Lol, motiondave is right, we should split this topic to make these valuable information reachable for all the other users will be searching of it in the future. That's how the forums works. However, I'm reading all the posts with interest.
