If the converter is truly isolated then you can connect the input ground and output ground wherever you want.
The only restriction would be the isolation voltage limit between the input and output (which is usually stated in the spec sheet).

you mean that if i am using 24 to 12v converter i will connect 24V and GND to input + & - pins and can get 12V and gnd at out + & - pins. And i can connect the rest circuitry to these output pins! it will work correctly?

24Vin between 1 and 4; 12Vout between 5 and 9. You can tie 4 to 5 or 4 to 9, or not tie input to anything on the output.

That is a cranky old part. Any reason you are not using their 2nd gen (Maxi, Midi, Mini) bricks? I've found them to be still a bit Vicor-weird, but not as weird as the VI-J.
