Slotted - parallel with top bars. Wires - perpenduicular.
The short slotted ones, if unframed or 'plastic' need to be at 90 degrees as it is extremely easy to have near 100% blockage of holes in the queen excluder from the top bars of the frames below.
For framed wired excluders (which IMHO are the only ones worth bothering with) I fit them at 90 degrees, always.
