A 2A mini blade fuse and several connection options for the ignition sensing cable are also
supplied.
•
Never replace a fuse with one that has different amperage than the original on the DC Input,
Output and ignition positive cables.

Use the low resistance cable that is supplied with the charger for all the DC connections between
the battery charger and the battery bank.

The battery charger is supplied with input (red) and output (white) 10mm² cables, with a length of
5 meters on the input and 4 meters on the output.

The input (red) and output (white) 10mm² cables can be cut down to length to suit the
installation.
