Wiring a fused fan isolator

[AzK]

I bought a Xpelair CV4SR extractor and also one of these fused fan isolator switches: https://www.click4electrics.co.uk/c...n-isolator-switch-with-3a-fuse cma3020-p-9009

Has anyone wired one of these switches before, or would they have any idea what 'L out' and 'L in' wire into?

The fan has 3 connections: T, L, N

I am planning to wire it as follows:

L1: Black, Switch Live (to T)
L2: Brown, Permanent Live (to L)
N: Grey, Neutral (to N)

That being the case, how do I wire 'L out' and 'L in' ?

 

[He who knows]

They are the terminals for the fuse, which surely should be obvious given the position of them being directly behind the fuseholder.....

But what on earth do you expect the fuse to do? Why did you buy that rather than an unfused one?
