protección por fusible

Okay, thanks for clarifying and confirming that the original is duff! Unfortunately, it's pretty standard for technical documents; I've seen muuuuuch worse, as I'm sure we all have. When I studied chemistry we had a module on scientific communication and reporting, but I don't think engineers and the like receive any such course.

"He" refers to whoever wrote the Spanish text. Sorry for not having included this, but I answered from the phone and, as my father used to say, in Spanish, "hijo, tienes manos de joyero. De joyero de hacer "joyos", quiero decir, no joyas".

"He" knows what he is writing about, but he should keep in mind that he writes for the remainder of mankind to understand, not for he alone. Especially if that may electrocute somebody.

Patinba,

The semi-colon is there because it's a list, not a single sentence, so the first and second items in the list are not necessarily connected. But I get what you're saying, thanks.

psicutrinius, sorry but who are you directing your comment at? Who does "he" refer to?

Logically a fuse provides protection, so you would not disconnect it to protect anything.

How about “The safety devices may only be disconnected in the following cases: to carry out maintenance and repair work after disconnecting the generator from the power supply, * after installing a fuse to protect against any renewed start-up of the generator.

* comma instead of semi-colon?

Is to learn to write.
No way to get additional context on that. I would say that "The safety devices should be uninstalled ONLY for repair or maintenance work upstream of the fuses if and after the generator or the supply from the net has been open (cut).
