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
easier 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
environments. 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 electrolysis
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
interference, or if such a switch is not available, we recommend
connecting direct to the battery and installing an in-line switch.
This will let you shut off power to the power cable when the unit is
not in use. When you are not using the unit, you should always
shut off power to the power cable, especially when the power cable
is disconnected from the unit.
WARNING:
This product must be independently fused with the
enclosed 3-amp fuse (or equivalent), even if you connect
to a fused accessory or power bus.
