The Power/Data cable for this unit.
NOTE:
There are two basic power connection options, which are shown in
the following two diagrams. Read the following instructions
carefully to determine which power connection applies to
your unit. Depending on your configuration, you may not use all of
these wires.
Caution:
All of the wires in the power/data cable have bare ends for eas-
ier installation. The bare ends on any unused wires could cause
an electrical short if left exposed. To prevent this, you should
cover the individual wire ends – either by capping them with
wire nuts, wrapping them with electrical tape or both. (You
should cut off the bare wire before taping off the ends.)
Powering Your Display Unit
The display unit works from a 12-volt DC battery system. Attach the
display power cable (with provided 3-amp fuse) to an accessory switch
or power bus. If this results in electrical interference, connect direct to
a battery but install an in-line switch on the cable.
Caution:
We strongly recommend that you shut off the power supply to the
power cable when the unit is not in use, especially in saltwater en-
vironments. When the unit is turned off but still connected to a
power supply, electrolysis can occur in the power cable plug. This
may result in corrosion of the plug body along with the electrical
contacts in the cable and the unit's power socket. Risk of electroly-
sis corrosion is even greater when the cable is unplugged from the
unit, but still connected to a power source.
We recommend you connect the power cable to the auxiliary power
switch included in most boat designs. If that results in electrical
