ᐅ Ikea Realistik Tjänling oven and ceramic cooktop connected to a high-voltage power cable

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

However, I already have a ceramic hob connected to a high-voltage supply.

How is this supposed to work?

PS: The IKEA staff member told me that the oven would be connected to a standard power outlet.

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

Do you have a separately protected outlet for the oven?

Yes. I would have had it.

Now the electrician has connected everything.
