help needed with RCD identification/wiring

[Trampaq]

Hi
I'd like to install an RCD in a shed, I have 2 good units that were removed from a working installation long ago that I'd like to use instead of buying a new one.
The problem is that they don't have the 1-2-3-4 indicators on how to wire them and can't find their datasheet online/google
Would any of you tell how to wire any of them? I only need one...
I assume Live goes on the left and neutral on the right, but is the load to be connected at the top or at the bottom? Does it matter?

the LE says V/304-026031 660441
the Hager says U762 u2 20470

The RCD needs to be matched to whatever brand of consumer unit & MCBs you are using. That said, from the photos, not sure I'd want to be using either.

What are you installing these rcds in and what is it protecting.

What are you installing these rcds in and what is it protecting.

in a small fusebox, it's protecting a B16 breaker(for 4 sockets) and a B6 breaker (for lights)

Can you show a pic of this fuse box.

can't think how knowing the fuse box I'm going to use can help with this but here you go

Don't you have to be registered in Ireland to carry out electrical work?

Those RCD's look like they have had a hard life I think they would want testing before even considering using either of them
