8 MW810 Mobile Workstation Vehicle Installation Manual
Be sure that the vehicle’s electrical system is in good condition. Faults in the alternator and
ignition system can be a source of severe Radio Frequency Interference (RFI) and can result
in MW810 Mobile Workstation operating problems. Correct any problems in the alternator
output, ignition system, and battery condition before beginning the installation.
The vehicle must have an alternator that can produce a high-current output at low speed
(below 18 m.p.h. or 29 km/h) and in an idle state. It also needs the highest rated heavy-duty
battery available for the vehicle. The power cables of the MW810 Mobile Workstation
should be directly connected to the power system of the vehicle.
Ground Polarity
The MW810 Mobile Workstation should operate only in negative ground electrical systems.
Check the ground polarity of the vehicle before starting the MW810 Mobile Workstation
installation to verify that the polarity is correct. Accidentally reversing the polarity will not
damage the MW810, but will cause the cable fuses to blow.
Due to advanced vehicle assembly techniques, different parts of the vehicle chassis may not
be connected to the battery negative terminal. Connecting the ground leads of several devices
with a common power supply into different location on the chassis, may cause GROUND
potential differences between these locations and damage the MW810 Mobile Workstation or
any other installed equipment.
FIRST CHECK that the vehicle chassis point to which you are about to connect the
negative lead is properly connected to the battery negative terminal. If the chassis is not
properly grounded, connect the negative lead directly to the battery's negative terminal.
When the CPU Box and the display are mounted on a Gamber Johnson mount or next to each
other, use a 10AWG ground wire to connect between the body of the CPU Box and the
display. The ground wire ring lugs should be connected, on one side, to one of the screw
holes used to secure the CPU Box to the trunnion, and on the other side, to one of the screw
holes used to secure the display to a surface.
VERY IMPORTANT : Connect the GROUND lead of any device that is connected to the
MW810, i.e., radio or any other equipment, to one common chassis point, via a ring lug, as
DO NOT install the workstation in a vehicle with a positive-ground electrical system.

Caution
Avoid using power Battery Saver relays that cut-off power ruthlessly between the
MW810 Mobile Workstation main power and the power system of the vehicle.
Uncontrolled power cut-off can damage the MW810 Mobile Workstation
operating system and may require re-imaging of the hard drive. If a power cut-off
device is used in order to conserve vehicle battery life, please consult a qualified
Motorola authorized installation shop or contact the Motorola system support
center for assistance.
