I have a kelly KLS 7240D controller(http://kellycontroller.com/kls7240d24v- ... -1377.html
). I am confused with B+ and B- terminals wiring as there are two sets.
1.) Terminals that should be connected to the battery,shown in this picture.
2.) Wires shown here in this picture,
So my question is what terminals are shown in this diagram(Highlighted). Is it 1.) or 2.) ??
Also if it is 2.) What should be the rating of fuse and main contactor??
I have searched this in the internet but couldn't find any solution. This might be very obvious thing which everyone leaves out.
