• 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.
1
Route the power cable to the power source and to the device.
2
Connect the red wire to the positive (+) battery terminal, and
connect the black wire to the negative (-) battery terminal.
3
Connect the power cable to the device, and turn the locking
ring clockwise to tighten it.
Additional Grounding Considerations
This device should not need any additional chassis grounding in
most installation situations. If interference is experienced, the
grounding screw on the housing can be used to connect the
device to the water ground of the boat to help avoid the
interference.
Power Cable Extensions
If necessary, the power cable can be extended using the
appropriate wire gauge for the length of the extension.
