How to connect LED drivers to 220v suply

[Yukster]

Sorry for the newbie questions. I got three Mean Well 12v drivers and three 12v COB LED strips to light three shelves. As seen in the pic, I have two pairs and one single flexible (220v) connected to a lights switch to power the drivers. Can someone here have a wiring diagram that I can use to ensure that I wire the 220v AC supply to the drivers correctly. TIA

Is that flex coming out of the wall?

Yes it is. It's been set up by electrician during renovations.

This is rather odd, is that a stud wall? Where is the nearest power in relation to the wires? I would have though they should all be able to be connected together on one power source/switch

Why hasn't the electrician wired them into a junction box of some description and just left them dangling out the wall?

It's not a stud wall. it's an external wall.

I'm not sure what you mean. All three wires are connected to one switch on opposite wall.

Not sure about the junction box and what the electrician do or not do and why.

Regarding how to wire the led to existing wiring, any suggestion would be appreciated.

I have two pairs and one single flexible (220v) connected to a lights switch to power the drivers.

The wires connect to the 230V side of the driver. Two of them will have 2 wires in each terminal, the other only a single wire.
The LED strips connect to the 12V output.

The more usual method is to locate a single driver out of sight in a more convenient location and then run the 12V cable to each shelf.

Thanks you! You're the first person to actually answer my question.

I think it was done this way to conceal the 230v power feed for each of the shelves. I left the electrician to do this how he saw fit. He could have run 12v wires from the top to middle to bottom shelves to connect to the LEDs to apply the more usual method.

I am now wondering whether to stick with the 230 wiring i've got, or to use the more common method?

If the latter, what do I use to split the 12v output of the driver to feed 3 led strips? My driver is Mean Well LPV-35-12. Also, is this wire suitable as a 12v wire for this installation? The shelves are 1m apart.
