Note: These distances are for a 2 wire power cable run from the battery to
the display (approximately the distance from the battery to the display). To
calculate the round trip length, double the figure stated here.
Breakers, fuses and circuit protection
The power cable includes an in-line fuse. It is recommended that
you fit an additional thermal breaker or fuse at the distribution panel.
