If you want to wire it to code, the converter should have a dedicated #8 conductor to bond it to the frame. I can't find anything about bonding the fuse panel. I'll keep looking.
Edit: There is a cover-all provision that says any equipment exposed metal parts that may become energized shall be bonded to an accessible terminal on the frame. Again, it requires a #8 conductor. Presume this would apply to the fuse panel. I also assume you are talking about the DC fuse panel.
