how to install a beko s 520 electric cooker?

how is the correcgt way to do this, it seems different from my old cooker. i cant get it to work.
.

could someone please tell me step my step or a diagram of how it should all fit together.

my dad fitted my last electric cooker and the one before that.

at one stage he got the cooker working but the oven wouldnt work and another time 2 of the hobs were working but not the other two hobs.
