Vehicle Power Supply Installation Guide

Input Power Cable

NOTE:

The input power cable may be shortened as needed. It SHOULD

NOT be extended under any circumstances.

The input power cable is approximately 9 feet long. One end

has a 4-pin connector, the other end has a 2-pin connector. By

cutting off the unneeded connector, a single cable can meet ei-

ther low or high voltage input-range power supply require-

ments. The cut end is then terminated for connection to the

vehicle power source.

Inline Fuse

A snap-twist inline fuse holder is furnished as part of this kit.

It must be connected as close as possible (electrically

and

physically) to the vehicle power source. It provides short-cir-

cuit protection for the entire input power cable and the power

supply input. The fuse holder contains a 3AB, 20 ampere/250

V dc (

”) fuse. Should it fail, diagnose the problem

and correct it, then replace with exactly the same size and type

fuse.

Output Power Cable

NOTE:

Ensure that you have the correct output power cable for the comput-

er(s) being installed in your location.

Output power cables are approximately 6 feet long and have

a durable 3-pin connector to mate with the power supply. The

connector on the far end of the cable is specific to the teminal

(computer) or docking device in your particular installation.

These rugged connectors have heavy duty metal housings and

enhanced strain relief to provide added reliability in the mo-

bile environment.
