3.
From inside the vehicle, route the red and black power cable leads (without lugs attached) through
the access hole into the vehicle’s engine compartment, using accepted industry methods and
standards.
4.
Locate the nearest available vehicle chassis ground mounting point and shorten the black lead to
remove excess cable length.
5.
Install the supplied Ring Lugs onto the stripped end of the black and red lead at the end cable.
6.
Position the fuse holder as close as possible to the battery, ensuring that it is not close to any hot
engine component.
7.
Connect the black lead to the vehicle chassis ground. DO NOT connect the black lead directly to the
battery’s negative (–) terminal.
8.
Remove the Fuse from the Fuse Holder and connect the red lead of the power cable to the positive
(+) battery terminal. Verify that the adapter cable is connected to the red lead of the main power
cable.
9.
Plug the fuse into the fuse holder.
Cable Routing
•
Before a wire is run or a hole is drilled, inspect the vehicle and determine how and where you
intend to mount the LXN 500, antennas and other parts.
•
Plan wire and cable routing to provide maximum protection from overheating, battery acid, moving
parts and sharp edges.
•
Keep cables away from ignition circuits to reduce noise pickup in the radio equipment.
•
Verify that the cables are of sufficient length. Do not connect two short lengths with a connector;
doing so will result in signal loss. Refrain from loose excess in the cables, but leave enough slack
to allow reconnecting if necessary.
•
Do not run cables externally or underneath floor mats.
•
Do not locate cables where they can be kicked by the driver or passengers or where they can
interfere with operation of the driver’s foot pedals.
•
When routing the cable, refrain from creating sharp bends or kinks.
•
Cables must be routed through special UL listed conduit/duct for electrical cables. This
conduit/duct must fully enclose the cable along its whole length.
Installing the Optional Power Protection and Back-up Unit
The Power Protection and Back-up Unit (NAV-PAC) is an optional unit that protects the LXN 500 from
Voltage spikes during engine cranking, power surges, momentary power losses, abrupt voltage changes
and noise interference on incoming from the vehicle power system.
The NAV-PAC includes a back-up battery pack that acts as a power reservoir and is charged from the
vehicle battery. In the event of a drop in DC Voltage due to engine cranking or total power interruption,
the battery maintains power to LXN 500 for a limited period of time. This is essential for preventing brutal
shut-down, and memory or data loss.
CAUTION
Failure to mount the red lead of the power cable directly to the battery may result in
severe alternator whine interference.
