You need a circuit installed that can deliver 19.58amps. If you have an existing cooker circuit that you are not using and the fuse reads higher than 20amps you can have the hob connected to that.
Otherwise you need a qualified electrician to install a new circuit.
The kitchen already has this, labeled as E-herd (electrical stove) in the circuit breaker cabinet thingy. That’s why I wanted to go for three phase, it has three fuses rated for 16A.
4700w / 240v = 19.58amps
