advice on grounding lamp and ballast required

Greetings to DIY community,

That's my first DIY experience, and I literally have zero experience with electricity. I would appreciate any advice if I am missing or doing something wrong here.

I am trying to wire a Philips TUV 55W PLL lamp with a WH43-UNV-L ballast according to the Fulham datasheet (diagram. 12). I know that this ballast is discontinued for now, but at least I managed to get it at this time. In addition, I know that this lamp type expects programmed start instead of instant start one.

The documentation states "This ballast case must be grounded".

Let's say I am going to use this type of cord, would attaching "green" wire to the ballast's box would be enough to be "grounded"?

Thank you!
