When the LXN 500 and the mobile workstation are mounted on a mount or next to each other, use a
10AWG ground wire to connect between the body of the LXN 500 and other units. The ground wire ring
lugs must be connected, on one side, to one of the screw holes used to secure the LXN 500 to the
mounting bracket and on the other side to the vehicle chassis.
IMPORTANT
Vehicle common ground points (chassis) should be measured against the vehicle battery
negative terminal for no more than 1/2 Ohm.

Connecting the LXN 500 to Power and Ground
Installing the Power Cable
Perform this procedure to install the LXN 500 power cable.
Procedure:
1.
Determine a routing plan for the power cable, taking into consideration the location at which the unit
is to be mounted, and the location of the vehicle battery.
2.
To pass the power cable through the fire wall and into the engine compartment, locate an existing
hole with a grommet in the vehicle fire wall, or drill an access hole at the desired location. Insert a
grommet inner diameter into the access hole to avoid damage to the cable (See
Figure 3-5 ). Take
special care not to damage any existing vehicle wires.
