Help with Perilex plug

[absalom]

Hello, apologies for English. I am an American living in the Netherlands. I am also not familiar with 3 phase or Perilex plugs.

We are attempting to replace an old electric hob with a Bosch induction hob. However, when I plugged the Bosch into the old outlet, I received error codes on the hob indicating incorrect voltage. It seems that the Perilex plug included with the Bosch hob isn't wired correctly for our house.

Here is the wiring diagram for the old hob that was successfully working with our outlet:

And here is what I have wired the Perilex plug for the new Bosch to look like. Is it possible to confirm that I've done this right?

Here is the wiring diagram for the old hob

That's not the wiring diagram for the old hob, that's just the label on the cable used.
The cable often isn't included with the hob, so it was propably bought separate.

This label doesn't really say anything.

To wire your new hob you need to know which kind of group is installed, either a 2x16A "kookgroep" (2 phase, or 2x1 phase) or a 3x16A "krachtgroep" (3 phase) and you need to know how the outlet is wired.

Could you send a photo of the electrical panel? Do you by any chance have a voltage tester? Measuring the voltage between each pole of the Perilex outlet and earth says a lot.

Here are photos of the panel. Are there any parts that I should take closer pictures of? Also, yes I definitely have a multimeter! Which poles should I measure? Thank you!

 

[XanderH]

Ok it looks like you have a real 3 phase group for the hob.

Measure voltage between all (4) poles and earth (the middle pole). One pole should measure ~0V, that's neutral. Three should measure ~230V, those are the phases. Also measure between the phases to be sure, you should measure ~400V.

Ok, I will double check these measurements today.

But assuming that I have 3 loads and 1 neutral, does that mean this hob is not compatible with our outlet? I see that it will only support two loads:

I am also not familiar with 3 phase or Perilex plugs.

As you already found out, these plugs can be wired in different settings, depending on the wiring and installed compounds on the meterboard and the internal wiring in the electric hob.

Therefore I would strongly recommand to hire an expert (electrian).

 

[XanderH]

Your hob is compatible, but it will only use 2 of the 3 phases.

Hi XanderH - I measured the outlet, sure enough 220v in 3 of the 4 ring terminals relative to ground in the center. So I cleaned up the wiring and plugged the hob back in. Unfortunately, the hob is still displaying backwards 9 and then 1 on the two right burners - I suspect I damaged the hob when I plugged it in to the incorrect voltage yesterday, my fault .

Have you come across this error before?

Update: it appears I blew an AC/DC converter, PN# LNK304GN. I will order a replacement and try again. Thanks for all of the help so far. XanderH - if this works, I'll be sending you a tikkie for the help!

 

[XanderH]

So you've determined which pole is neutral? Is it in the top left corner?

If so, it seems like you've wired it correctly. Did you try other combinations before this one?

P.S. Are the blue en grey wire joined in a cable end-sleeve as shown on the label? Or did you cut the end-sleeves installed in the factory? You shouldn't use wires without end-sleeves for high current applications like this, and you should't connect two seperate wires in one screw terminal.

In that case some other components may be blown as well. In topics about washing machines and other household equipment, a lot of such ICs have been reported blown, where (as a result) protecting resistors or fuses have been blown as well.

Maybe you post some photos of the opposite site of the board.

BTW. Not every damage to electronic components will be visible. Possibly the overvoltage may have caused much more damage to the board than what easily is viewable.

 

[absalom]

@XanderH yes, it seems I've wired the two neutrals incorrectly (missing crimp connector), I will fix this.

@Kees it appears that I've also damaged one of the IGBTs (pointing to with finger).

@Kees it appears that I've also damaged one of the IGBTs (pointing to with finger).

Possibly much more has been damaged, like the processor(s) itself.

And there must have been some fuse or protecting resistor, which certainly will have gone too, somewhere in this area:

Varistors (the light brown disc-shaped devices) may have gone as well...

Probably you will need a new board.

 

[absalom]

@Kees You're likely right. I'll replace these components, but I am prepared to buy a new board if necessary.
