Thx alot for the help. I got it now. FG = Floating Ground. I just hooked up the ground to FG and the AC wires to both AC inputs. Its an inverter or an transformer.
I had to open it to find a wire that i could put on 110v or 220v.

I feel stupid for asking about it, but i didnt want to fry the thing. I'm going to use this for a door locking system with some kind of dead bolt and other home safety features. Maybe a 2"x4" wooden beam straight across the door...

My new apartment is going to be like Fort Knox.

Thx all

The symbol next to the FG looks a bit like the "Earth" ("ground") circuit symbol.

"FG" is mostly likely "frame ground", the same as an earth ground...

AC 1 and AC 2 are the 220V input. AC has no polarity, so it doesn't matter which is which.

Be sure it's set for 220V input. "Switchable" isn't the same as a "switching" power supply, many of which have a wide input voltage.

. Frame Ground sounds as likely as Functional Ground to me. I'm pretty sure that it's not Floating (floating grounds are usually a bad thing).

I'm with you--whatever the F in FG is, it isn't likely to be Floating...

It's probably Floating Ground because it looks like the connected wire (the upside-down T) is floating above the actual ground.

. Connect the 220VAC incoming power to terminals AC1 and AC2. It doesn't matter which wire goes to which terminal, it's AC. The mains ground goes to FG.

PPS: FWIW, it seems that the F in FG stands for Functional.

PS: And make sure the 110/220 switch is in the 220 position.

According to the one page that had one line listing it, which was in Polish, it's some kind of inverter. Maybe for neon signs or something like that, because the other things seemed to be lighting-related.
"Power - Glendale's inverter MODEL: GE-009B 85W (+5 V/11, 12 V/2A; -5V/1A) - 25 PLN" in the last post of this thread.
