Battery charger chassis ground - where does it go?

[leecea]

I'm replacing my existing battery charger (which isn't working properly) with a new Sterling ProCharge.

In the Sterling manual is says there are three grounds - the AC ground, the DC negative, and the chassis ground which is a small terminal on the side of the case. Then it says "In most installations all these will end up at the same point".

My existing charger doesn't have a chassis ground connection. So where should I run this wire for the new charger? Do I just connect it to the same busbar that the DC negative is connected to?

Thanks,
Andy

Yes To the main dc neg bus of the boat.

Cable size same as dc cables or 1 size smaller. ( For abyc. )
