I'm powering an IT server rack on an inverter generator, through UPSs. The transfer from mains to generator will be manual (unplugging equipment from home and plugging into generator; there will never be any connection between mains and generator). For safety, I know I should bond neutral to "ground" at the generator. This system should run nominally and be safe from "ground faults" inadvertently making equipment cases live/hot.
But the whole system is now floating. Should I connect the generator "ground" to earth ground in order to put the whole system at a known potential?
Note that there is equipment like cable modems within the rack that have earth ground connected to them via their coaxial inputs. But I don't think the ground potential gets from them to the balance of the equipment through ethernet cables and such. Nor are any of these cables heavy copper in any way.
What think you?
