PE Cable?

In chapter 6 of the assembly instructions it talks about the PE Cable, it connects to the buddy board, the display and the PSU. I am told by support that it's a grounding cable. My MK3S+ (and I believe all others prior) did not have this cable. Is it necessary?

The reason I ask is that my situation is a bit unique in that my printer (and I) live on a sailboat, and I power it from my boats battery system. I can potentially run a grounding cable from the grounding plate on the boat, but that's a long run of wire. Support is asking the development team what happens if I don't connect this, but in the mean time, I thought I would ask here if anybody knew if this was necessary?

Best Answer by MysticGringo:

Support got back to me (always impressed with Prusa support). The cable is required for certification purposes, and they say it can be removed if necessary. I would advise anybody to keep it unless they are in a similar unique situation.

I believe it's to stop electric static from frying the lcd as that was a big  problem with mk3s
