RCD protector unit wall mounted

[ksporry]

Guys,
I got an RCD unit that is wall mounted from B&Q. The model is BS4293.
Basically it is only an RCD unit with a fuse.
The diagram that came with it, is an extremely poor copy.
This hinders me as I now don't know how to wire the earth! There are 2 earth connections on the unit. One has the indication "E", the other has the indication "SE".
Where do I wire the earth of the load and where do I wire the earth of the supply?

Earth of the supply/supply earth/SE?

BS4293 is the standard to which the RCD should operate.
Is there a maker's name on it.?
I seem to remember having to deal with a Volex RCD that had the same two terminals and unreadable instructions but do not recall how it was wired.

It's a nameless B&Q brand. The "manual" mentions a company called Electrium Sales Ltd.

Ah, I just read in font size 2 that for electrical safety the two earth connectors "E" and "SE" should be linked together.
It also says "When using product for clean earth facility no link wire is required". What does this mean?

Big company, own serveral decent brands such as Crabtree and Wylex, yet also own Volex and Marbo! not sure if they also do own brand stuff
