Coat hook rack above a wall with fuse boxes

The plan

I'm planning to build and put up a coat hook rack in my flat. My plan is to simply screw 5 hooks into a solid piece of wood and then mount it on the wall. It should look something like this:

only a bit simpler.

However, the wall on which I would like to mount the rack looks like this:

As you can see there are some fuse boxes. The box on the bottom is for the underfloor heating. The boxes above are for fuses. The rack should be mounted above the boxes.

Now to my problem

Due to the fact that I want to mount the rack on a wall with fuse boxes (where there are probably many cables behind the wall), I don't know how (and even if) I can mount a rack onto the wall. I think the use of dowels isn't a good idea because of the cables, correct? I was thinking about mounting it from the ceiling (perhaps using 2 ropes, I know this won't hold just to give you an illustration) but this didn't seem like a good idea to me.

My Question

Do you have any ideas on how to mount the rack onto the wall and do you even think that this would be possible?

Thank you in advance!
