Connection Considerations; Connecting To Power; Garmin Marine Network Considerations - Garmin GPSMAP 8X10 Installation Instructions Manual

The pieces of the foam gasket have adhesive on the back.
Make sure you remove the protective liner before installing
them on the device.
19
If you will not have access to the back of the device after you
mount it, connect all necessary cables and install microSD
cards in the back of the device before placing it into the
cutout.
NOTE: To prevent corrosion of the metal contacts, cover
unused connectors with the attached weather caps.
20
Apply marine sealant between the mounting surface and the
device to properly seal and prevent leakage behind the
dashboard.
21
If you will have access to the back of the device, apply
marine sealant around the cutout.
22 Place the device into the cutout.
23 Secure the device to the mounting surface using the included
M4 screws or wood screws, depending on the mounting
method.
24
Carefully remove and discard the rubber protective bumper.
25
Wipe away all excess marine sealant.
26
Install the trim caps by snapping them in place around the

Connection Considerations

When connecting this device to power and to other Garmin
devices, you should observe these considerations.
• The power and ground connections to the battery must be
checked to make sure they are secured and cannot become
loose.
• The cables may be packaged without the locking rings
installed. The cables should be routed before the locking
rings are installed.
• After installing a locking ring on a cable, you should make
sure the ring is securely connected and the o-ring is in place
so the power or data connection remains secure.

Connecting to Power

When connecting the power cable, do not remove the in-line
fuse holder. To prevent the possibility of injury or product
damage caused by fire or overheating, the appropriate fuse
must be in place as indicated in the product specifications. In
addition, connecting the power cable without the appropriate
fuse in place voids the product warranty.
You should connect the red wire to the same battery through the
ignition or another manual switch to turn the device on and off.
1
Route the power cable between the power source and the
device.
2 Connect the red power wire to the ignition or another manual
switch, and connect the switch to the positive (+) battery
terminal if necessary.
3
Connect the black wire to the negative (-) battery terminal or
to ground.
4
Connect the power cable to the device, and turn the locking
ring clockwise to tighten it.
Additional Grounding Consideration
This device should not need additional chassis grounding in
most installation situations. If you experience interference, you
can use the grounding screw on the housing to connect the
device to the water ground of the boat to help avoid the
interference.
WARNING
Power Cable Extensions
If necessary, the power cable can be extended using the
appropriate wire gauge for the length of the extension.

Garmin Marine Network Considerations

A Garmin Marine Network PoE Isolation Coupler
(010-10580-10) must be used when connecting any third-party
device, such as a FLIR camera, to a Garmin Marine Network.
®
Connecting a Power over Ethernet (PoE) device directly to a
Garmin Marine Network chartplotter damages the Garmin
chartplotter and may damage the PoE device. Connecting any
third-party device directly to a Garmin Marine Network
chartplotter will cause abnormal behavior on the Garmin
devices, including the devices not properly turning off or the
software becoming inoperable.
This device can connect to additional Garmin Marine Network
devices to share data such as radar, sonar, and detailed
mapping. When connecting Garmin Marine Network devices to
this device, observe these considerations.
• All devices connected to the Garmin Marine Network must be
connected to the same ground. If multiple power sources are
used for Garmin Marine Network devices, you must tie all
ground connections from all power supplies together using a
low resistance connection or tie them to a common ground
bus bar, if available.
• A Garmin Marine Network cable must be used for all Garmin
Marine Network connections.
◦ Third-party CAT5 cable and RJ45 connectors must not be
used for Garmin Marine Network connections.
