Ground Connection

I see my HAB V3's have an external ground terminal, but there is no internal ground connection to the case, and the manual doesn't mention grounding.

An ohmmeter shows that both battery terminals are floating, insulated from the box.

What is the external ground connection for -- lightning protection in exterior installations?

Thanks!

 

Hello Ray,

Thank  you for calling out this omission!

Yes - lightning protection.  Also, we had installers who were dealing with AHJs (authorities having jurisdiction) who, according to their code interpretation, insisted on a ground connection on the HAB case.

We will address this in the upcoming version of the HAB manual.

Thanks again.
