Bosch PIE631FB1E - Connecting the induction hob without a protective conductor

Hello. I want to connect a 3-phase induction hob. I know that the topic has been rolled many times but I have not found a connection without a protective conductor. Well, I have a three-phase system in my home but I do not have a protective conductor. In the mailbox I have only L1 L2 L3 N (unless it is PEN because only N can be as I remember correctly from school: p)
I did not have any strength in the kitchen. So I chose the two least-loaded phases and the neutral wire and pulled it into the kitchen. The disc uses only two phases anyway. And now you have to connect it.
In the picture I drew what I would like to connect. This is the schematic of connecting my CD.
The phase conductors are rather a different connection option. It is not only about the additional jumble of PE with N, as it is done with sockets. Can I connect the disc in this way?

What for? So you need grounding for happiness?

Buddy peter falk you so seriously or are you kidding me?

Theoretically, Buddy, yes, grounding is needed in accordance with current regulations.
But you need to know the structure of this board and state that all metal elements are isolated from the network for design reasons.
So the power module is isolated from the potential through the plastic housing.
In addition, the customer is in direct contact with the glass, and this is an excellent dielectric.
So you do not have to "connect" the connections by force, although it should be in connection with the regulations in force.
As a result of a fire, for example, a plastic housing can "charred" carrying the risk of electric shock as a result of touching the plate from the bottom, to the metal part. Differential current protection will not work in this case
But the Darwin Prize guaranteed ...

PS. Bridging zero with PE (on the board connection) has some sense. But in the case of "burning" zeros can be deplorable costs ... repairing the disc
Too big risk.

As for what djlukas wrote, let me connect according to scheme with two neutral wires.

From what I read the third way to connect with 2N is not in our country because we need two neutral wires that we do not have.

As for the connection, however, I decided that I would not be bridging N with PE

And why should I not connect to terminal 1 if it is so in the schematic?
In total, I was just wondering why this one phase is connected to two terminals. I thought that maybe this terminal is inactive and only connects so that one wire does not remain free.

Exactly, this clamp leads nowhere. Is free. And you connect the cable and "do not dangle" ...

Are you sure about it 100%?
Because it's strange that this terminal is not used

I'm sure at a million percent.
The one or two clamp (photo number one) is unused (inside).
The lack of bridge application results in a stress-free connection of the device. The two phases are disconnected.
But still remember that in order to use the guarantee, a physical visit must be made to the service technician who will sign the installation and provide a letter (paper) confirming the correct connection of the equipment to the existing installation.
Dot and AMEN!

Now I'm calm. Thanks for the info. Pozdr.
