Cameo Screw

electric wiring advice?
I have a Belling Cameo free standing cooker, I have the cable from the switch etc and need it to connect to the cooker. I have a diagram on the back stating the right way to wire it but there is no holes to insert the wire?……there are large headed screws, does the wire just sit under them?
Sensible answers plz
There is a slot/gap under these screws (& to the left) for L & N .
The Earth slot/gap is above the screw head.
Screw it down reasonably tight and ensure that the wires do not pull loose when you try tugging.
Connect the cooker end of the wires first if you can…
