Refer to Figure 6.1 for connections.
1. First, connect the negative cable to the
negative (−)
battery post. The best way to secure
the battery cable to the battery post is by using a ring terminal . A bolt is sufficient to
secure the ring terminal onto the battery post; doing so will allow for great electrical
contact. Next, connect the bare stranded portion of the cable to the
negative (−)
battery
input terminal on the charge controller.
2. Similarly to the instructions described above, connect the positive cable to the positive
(+) battery post. For protection, an in-line fuse can be added to this cable. This is usually
done with a fuse holder. If opting for an in-line fuse, please do the following before
connecting the
positive (+) cable to the charge controller:

Make sure the fuse holder’s gauge wire size is matched.

Attach the fuse holder to the line with a butt connector or by soldering it.
The butt connectors recommended for this application are the type with heat shrink insulation.
This will keep will give extra protection for the internal connection.
Use a crimper to splice the Maxi fuse holder with the battery cable. Once a strong connection is
achieved, use a
heat gun to shrink the insulation on the butt connectors.
