"Use 230 Volts supply without grounding"?
Grounding via a grounding electrode at the generator? Not required.
Grounding via a green wire in the tool cord? Required.
How safe?
Depends. Grinding what and where?
Best solution is to use a GFCI with double insulated tool. With no green wire there is less path to ground. A shock can still occur.
As far as a download site, none that I know of.
