Wiring fan -> speed controller

[DiscoStu732]

Hi forum, this is my first post so hello to all.

I have a fan (RVK Systemair 125L) and a variac speed controller (Manrose 1350).

The fan requires an earth and I have already wired it successfully using a 3 core mains plug.

Now I need to wire in the speed controller. I can see how to wire in the Live and Neutral from the plug, and then on to the fan, this is easy.

Where I am stuck is what to do with the earth connection. The speed controller has no earth connection. How can I safely wire this, and what should I do with the missing earth?

[ Fan (L/N/E) ] -> [ Speed controller (L/N) ] -> [ Plug (L/N/E) ]

if you're breaking the cable in 2, just put the earth in a piece of connector block and tuck it in with the speed controller connections, job done

So the earth just bypasses the speed controller effectively, goes straight from fan to plug?

yep if the speed controller requires no earth, just take it straight to the fan
