1.6.2 Connecting the Wiring Harness to Power
WARNING
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 wiring harness 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 If necessary, install the locking ring and O-ring on the end of the wiring harness.
4 Insert the cable into the POWER connector on the back of the device, pushing firmly.
5 Turn the locking ring clockwise to attach the cable to the device.
Additional Grounding Consideration
This consideration is applicable only to devices that have a grounding screw.
Not all models have a grounding screw.
This device should not need additional chassis grounding in most installation situations.
If you experience interference, 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.
