Cable Installation
WARNING!
The MEGA Live Imaging transducer should be connected to a
main switch, fuse panel, or battery switch. Humminbird does not recommend
connecting to a battery without a fuse and a switch.
CAUTION:
Some boats have 24 or 36 Volt electric systems, but the MEGA
Live Imaging transducer MUST be connected to a 12 VDC power supply.
NOTE:
Humminbird is not responsible for over-voltage or over-current failures.
The MEGA Live Imaging transducer must have adequate protection through the
proper selection and installation of a 2 Amp fuse.
NOTE:
A 10' (3 m) power cable is included to supply power to the MEGA LIVE
Imaging transducer. You may shorten or lengthen the cable using 12 gauge
multi-stranded copper wire.
8a.
Main Switch/Fuse Panel:
If a fuse terminal is
available, 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 power,
and the drain/shield wire to the boat’s chassis
ground terminal. Install a 2 Amp fuse (not
included) for protection of the unit.
OR
8b.
Battery Switch:
Install the battery switch (not included) using the instructions
provided with it. You will also need to obtain and install an inline fuse holder
and a 2 Amp fuse (not included) for the protection of the unit. Attach the black
wire to ground (-), the red wire to positive (+) 12 VDC power, and the drain/
shield wire to the boat’s chassis ground terminal.
WARNING!
If you are unable to obtain a battery switch and are forced to
connect the power cable directly to the battery, be aware that this will drain the
battery. Humminbird does not recommend connecting to a battery without the
appropriate fuse and a switch.
NOTE:
The drain/shield wire is the non-tinned black wire.
9. Secure the cables along the route as needed for a clean assembly.

Cable Installation
NOTE:
You must ensure your MEGA Live ethernet
and power wires are installed in a location where
they will not be cut or ripped by the trolling motor
articulating or rotating. Wires damaged by improper
installation are
NOT
covered by the product warranty.

Ethernet:
Insert the Ethernet Cable into the Ethernet
port on the control head. Hand-tighten the screw nut.
NOTE:
If you have a HELIX Series unit with
Ethernet, connect the Ethernet Cable to an Ethernet
Adapter Cable (AS EC QDE, separate purchase
required). Insert the connector into the Ethernet
port on the control head or cable tray. See your
control head installation guide for details.

Route the power cable to the main switch or fuse panel (usually located
near the console). If you must connect to a battery, connect to a battery switch
(not included).
