Connect to Power and Ethernet
2. Connect to Power
The power cable can be connected to a fuse panel (usually located near the console) or to a battery. The
power cable for each unit in your system should be run as a separate, single length of 2-wire cable from
the unit to the vessel’s battery or fuse panel. Review the following information before connecting the
included power cable to the power supply:
• You may shorten or lengthen the power cable using a minimum wire gauge of 14 AWG (2.08 mm²).
You must also ensure there is a continuous suitable operating voltage at the product’s power
connector.
• The following power density levels do NOT occur at any point: 10 W/m2, 100 W/m2
NOTE: The power cable can also be connected to a factory-fitted power distribution point. The distribution
point should be fed from the vessel’s primary power source by a minimum 8 AWG (8.36 mm²) cable.
1. Route the power cable to the fuse panel or battery (12 VDC or 24 VDC
required). Make sure that the data cable connector can reach the
control head or Ethernet Switch location.
Fuse Terminal Connection
2a. Use crimp-on type electrical connectors (not included) that match
the terminal on the fuse panel. Attach the black wire to ground (–),
and the red wire to positive (+) 12 VDC or 24 VDC power. Install a 5
Amp fuse (not included) for protection of the unit.
OR
Battery Switch Connection
2b. Install the battery switch (not included) using the instructions
provided with it. You will also need to install an inline fuse holder
and a 5 Amp fuse (not included) for protection of the unit. Attach the
black wire to (–) ground, and the red wire to (+) 12 VDC or 24 VDC
power.
NOTE: The in-line fuse rating for the power cable is 5 Amp. The
thermal breaker rating is 3 Amp (if only connecting one device).
The suitable fuse rating for the thermal breaker is dependent on
the number of devices you connect.
NOTE: Humminbird recommends that best practice is observed in all vessel electrical installations,
as detailed in the following standards:
• BMEA Code of Practice for Electrical and Electronic Installations in Boats
• NMEA 0400 Installation Standard
• ABYC E-11 AC & DC Electrical Systems on Boats
• ABYC A-31 Battery chargers and Inverters
• ABYC TE-4 Lightning Protection
