Need help wiring retrofit T5HO lighting

I just got a fulham workhorse 5 fluorescent light ballast and endcaps, power cord, etc. that I need to retrofit my lighting in my new canopy. I've looked at the wiring diagrams provided on the fulham website for wiring 2 39W T5HO tubes but there is one thing I am hung up on. I have to ground the ballast somehow. My power cord I am connecting to the ballast has a hot lead (black), neutral (white), and grounding wire (green) but the ballast only has a hot (black) and neutral (white). Does anyone know what I need to do to properly ground the ballast?

Hook the green wire to the bolt or screw you use to attach the ballast to whatever it is attached to.

So it's just that simple? That's what I was thinking I had to do, but I wasn't confident enough in that to go ahead and do it without verifying that first. Thanks.

The ground is a pretty technical point that many don't really have options to use. In this case it can act as a case ground. Just connect it to the metal of the ballast or reflector. Often the mounting screw will be a handy thing to use. The ground and the white will both go back to the same point in the breaker box but it just doubles up on grounding.
