6040 earthing

[smeg up]

Hi

I know the subject of earthing some 6040 machines has been covered previously but I haven't found any answers for my situation.

The 6040z-s80 seems to be pretty well covered for earthing, most parts are being earthed to the mains as the emi filter is picking up a connection from the aluminium chassis of the control box.

Here is a picture of my vfd:



No earth connected, the power supply is not connected to earth either.

Here is a picture of my emi filter.



I was going to connect both the transformer and the vfd's earth terminals to the earth tab of the emi (as below).




Is this a good idea?

Cheers
