Ikea Realistik Tjänling oven and ceramic hob on high voltage cable

Hello, I just unpacked my Realistik Tjänling oven and was surprised to find that instead of a power cord, there is a high-voltage cable on the oven.

But I already have the ceramic hob that connects to the high-voltage.

How is this supposed to work?

Ps: The Ikea employee told me that the oven is connected to the power outlet.

Hello, the oven says: "For fixed installation. Must be connected by a qualified installer."

Would you have a separately fused socket for the oven?

Yes. I would have had [hätte gehabt].

Now the electrician has connected everything.
