Regardless, it should be well marked in green and have the 'earth' symbol on it - same for NEMA and IEC .

Edit: I found a FM50 manual, but doesn't seem to match your setup. It shows the incoming G is tied to the motor fame G and landed on a G-lug inside the chassis on the heat sink. If you don't have such a lug inside, then I'd put a ring terminal on both the incoming G and the motor frame G, then insert the chassis mounting bolt into the chassis, then thru both ring terminals, and then fasten all into whatever structure you plan for VDF mounting.
