I guess you have the Russian datasheet, like this one, from Dieter's site: http://www.tube-tester.com/sites/nixie/dat_arch/IV-21_IV-27.pdf
I don't read Russian, but they use "Ma", for mA, for currents, and "B", for V, for volts. That, and having used VFDs, it looks like the nominal filament voltage is ~2.5V, and the static anode, and ON grid voltage is 27V. Looks like 50V max. This is a multiplexed device. I don't know how experienced you are, working with VFDs, especially multiplexed ones. My first experience with VFDs, was almost 30 years ago. I bought some, with absolutely no datasheet, and no internet, from a surplus store. I first had to find the filaments. Those are the only two pins that show continuity. I applied a variable voltage, slowly raising it, until the filaments just glowed, in a dark room. Then I backed it off until it stopped glowing. With the filament on, I mapped out the grids and segments (anodes). I think it would be safe to use 25V for both the grids and segments. Remember to bias the filament/cathode to ~5V more positive, than the grid and segment most negative transition. Also, if you notice a brightness gradient (one side brighter), then use an AC source for the filament. The filament can run on either AC or DC, but the visual effect of running on DC, may not be acceptable. .
