Generic Chinese VFD, no CE and no earth connection to exposed metal heatsink

[magicniner]

The item was actually shipped from Germany.

It's just a 3rd party warehousing service used by a Chinese company from Shanghai.
On the bright side you should only have to send it back to the warehouse for a refund, then you can buy something with a CE mark ;-)

I've notified the seller of this and pointed out that if the unit isn't correctly bonded when it's installed it could be potentially fatal.

But your qualified electrical engineer would have spotted all that and either wired it correctly or condemned it :D
