POWER SUPPLY WIRING DIAGRAM
We recommended the installation of a switch and a (5A) fuse in the positive DC
supply to the ES502. The ES502 is active sending the digital depth through the
NMEA interface even when the power (chart plotter) is turned off, thus the need
for a switch.
In the example below you will notice the positive DC power connection is run
through a switch and a fuse before connecting it to the ES502 and the chart
plotter.
