COMMON GROUND CABLE CONNECTION
The common ground cable must be connected to a ground point that forms a common ground with all
components in your system. This can be achieved by connecting all grounds to a common ground busbar or
by a good quality connection to the vehicle chassis (if appropriate).

START BATTERY CABLE CONNECTION
Mount a MIDI/MEGA fuse close to the start battery (no more than 150 mm (6") in cable length) (1), then
connect the start battery cable from the Main Unit to one end of the fuse (2) — see page15 for
appropriate fuse sizing.
Connect a suitably sized cable to the other end of the fuse then to the positive (+) terminal of the start
battery (3) — see page13 for appropriate cable sizing.
