Kospel PPE2 Water Heater (9/12/15): Connecting Power Cord - Green-Yellow, Blue, Brown Wires

Hello,
can anyone tell me how to connect the cable to the Kospel PPE2-9/12/15 water heater?

The only thing I can guess is that I should connect the green-yellow wire to the far right screw, but I have absolutely no idea what the symbols U, V, W mean and where should the blue and brown wires be?

I am attaching a photo of the heater, greetings.

UVW is three phases. Do you have a blue phase? Insert a photo of the ends of the power cable because I would rather expect 2 black and brown, but in the end the colors are secondary, important where they are actually connected. I don't like to advise clients without any basis

I bought the cable myself, a regular 3-wire with a plug, I thought I would connect it to the heater, and the whole thing to the socket? But now I see that I must have miscalculated.
I wanted to install the heater this weekend in a summer house; I have poor internet access there, so I will ask now: if there is a 3-phase installation, what cables should I connect to the U, V, W marking?

After all, in the manual you have written 4x2.5 (3 phase wires + protection). If you don't understand, get an electrician.

I'm slowly starting to understand, and I've already done the electrics, but he doesn't really want to hit the dirt road for such "fuck":/

Just to make sure: I lead the phase wires to the latches marked U, W, V, and the protective wire in the last one on the right?
I found out by phone that there are 2 3-wire cables + 2 "loose" cables in the box ...

hello, I will ask here so as not to create a second topic, i.e. we connect the phase and protective wires, and where is the neutral? I would like to install an overcurrent switch, but in such a system it is probably not possible because we connect the phase and neutral wires there

Buddy, you have a 400V heater, not 230V, for this you need 3 phases and zero, i.e. the so-called "power" as you have it depends on how many kW you have purchased, such a standard is 17kW and you want to connect it to the socket with a cable !!! God save you because you may not survive this tinkering. Better call an electrician!!!
And I haven't seen 55A 400V 3ph before!!!
So you must have a connection of at least 22kW (power) !!!
Show what "corks" you have at the counter, we'll see what's in the grass!
Considering that this is a summer house, you probably have only 5.5 kW there, which means this heater is completely out!
To my friend arturartur24
And what type of TN, TT or IT installation do you have?
Do you have grounding or zeroing?
If you have an earth electrode, i.e. PE and N separated, you can connect
Are you talking about differential and not overcurrent?
If you can't tell, call an electrician!

I have a new installation and the protective and neutral wires are separated, you are right, I meant the current difference, only three phase and neutral wires are connected to the current difference, and three phase wires (marked u,v,w) and a protective wire are connected to the heater, and there is no neutral, which is why I was surprised

Because it is not needed because in 3-phase the work is phase-to-phase and 3-phase wires are needed and PE in home appliances is neutral N or PEN, once and now if there is no earthing, sometimes N is still connected as this protective PEN.
As for the connection in the differentials, the principle of operation of the differentials bows to you!

I am only asking for an answer how to connect the differential in such a system and whether it is possible since we do not use the neutral wire, as to the principle of operation, I do not know if everyone knows how a diesel engine works, but many have it

Unfortunately, my friend, call an electrician because the electricity does not touch him!!!
And does everyone who has a diesel repair and renovate it himself, probably not!!!
And with electricity, it's not a game, if you want to have a differential current protection, call an electrician!!!
Let him do everything right, it's not a school for "home heroes"

I repair it myself because I have full documentation of the car manufacturer, just as it is enough that you would draw me a diagram and it would be on topic! This forum is here to help each other, not to write to a specialist for any crap!

If you can read diagrams, then find a diagram of your differential and do it because, unlike the engine, it will not kill you right away, unless you breathe exhaust fumes and a differential that won't work, you won't even know when!!!
It's about your safety, it's not without reason that SEP exams are passed, etc., because everyone knows how to connect two cables, there is only an option, and here I will quote something to you:
https://www.elektroda.pl/rtvforum/topic1276827-2220.html#15824990
It's connected and working, right?
And here are the schematics:

It couldn't be right away

And what to look for, you don't want to or don't know how, you have to give everything on a platter!!!
The engine is also diagnosed for you and they bring only this and that to replace !!!

This heater requires a 3-phase installation with a power of not less than 15 kW. The value of the phase current is 22 A. This is how much power you need to have in the place of its installation. Electrical connections require knowledge and authorization. If you want to do it yourself, of course you can - you will do it at your own risk. Remember - safety comes first. If it is about connecting the wires, then the phase wires to the UVW terminals and the protection (yellow-green wire) to the terminal on the right side of the heater's thermal protection. Electric shock protection matched to the network layout of your electrical connection.
