Generic Chinese VFD, XSY-AT1 Programming Parameters/Settings

[JAZZCNC]

For info the unit that went bang on first switch on many years ago was a Huanyang, so you take your chances with anything in this sort of price bracket.

I've probably fitted 100+ Huanyang now and I've only had one go bang when turning on and that was when they first arrived on the scene 10+yrs ago. It only a Thermister and a very simple fix.
These newer Huanyang are much much better quality and very reliable, I've not had a single one fail in use.

This is from the link you posted https://www.banggood.com/2_2KW-220V-...r_warehouse=CN

In that link it shows the wiring as AC-AC-U-V-W-earth. So if that is correct putting earth and Live on the first two terminals would have only blown the MCB or fuse and should not have damaged the VFD.
