Be aware that the type of connector, wires and fuse will depend upon the max load the unit will draw. Use At Least the gauge and type wire the manufacturer recommends! Looking at the document provided above I see that they have conveniently provided +/-/grd terminals to attach to. They also tell what wire and max length you should adhere to. With that in mind, connect to your battery (bus bar?) with Ring Terminals properly crimped to the wire, dont use 'gator clamps'. A fuse should be within 6" of the battery +. I like MRBF fuse blocks.
