Well, not only do I have almost no hands-on tech experience - I don't understand Dutch. Is there a way in which you can explain to me in English what you are referring to? By "breaker cabinet", do you mean the switching power supply (a.k.a. the "power brick" located at the end of the cord)?
Are there English-language instructions located somewhere (that's preferably novice-friendly) on how to do this?
