I've just bought a generic 3.0Kw spindle and VFD off Amazon and the first thing I noticed when unpacking it is that there is no CE mark on either the VFD or in the documentation, I though all electronic devices sold within the EU had to carry the CE mark to show compliance with EU safety standards?
Secondly, and more worrying is that the "Earth" terminal in the VFD is only connected to the backplane of the PCB it's mounted on, there is no protective earth connection to the large exposed aluminium heatsink on the back of the unit, meaning that this could potentially carry 240v if there was a fault in the unit, without tripping the breaker.
I'm intending to take this up with the seller, but I don't suppose I'll get much of a response. I will also to notify Amazon that they are carrying non compliant and potentially lethal electrical goods and hopefully they will delist them, question is are all Chinese VFD's like this?
