Installation 11

Environmental Considerations

Consider the environmental parameters listed in the General Specifications section before

installing the MW 800.

Electrical Guidelines

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 MW 800 operating problems. Correct any problems in the alternator output, ignition

system, and battery condition before beginning the installation.

The power requirement for operating the MW 800 is 13.8VDC +/- 20%, 15A, negative

ground. 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 MW 800 should be directly

connected to the power system of the vehicle.

Cables longer than 10 ft. (3.05 m) should be routed through special UL listed conduit/duct

for electrical cables. This conduit/duct should fully enclose the cable along its whole length.

Mobile Antenna Installation

Vehicle antennas must be installed external to the vehicle and in accordance with:

• The requirements of the antenna manufacturer/supplier.

• Instructions in the installation manual of the external radio (in case an external radio is

used).

For operation in hot climates, the vehicle must be adequately

ventilated (for temperatures see General Specifications section).

Caution

DO NOT install the workstation in a vehicle with a positive-ground

electrical system.

Avoid using power Battery Saver relays that cut-off power ruthlessly

between the MW 800 main power and the power system of the vehicle.

Uncontrolled power cut-off can damage the MW 800 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..
