Intermec PB42 Vehicle Power Install Kit Installation Instructions - Page 6

Determining Your Vehicle's Voltage Level Before installing this kit, make sure that your vehicle's electrical system is in good working condition for all types of installations. The charging circuit must work properly and vehicle generated electrical "noise" must be minimized. Excess electrical noise can be severe enough to defeat the electrical filtering that is built into Intermec cables, printers, and vehicle docks. Defective ignition wiring, damaged insulation, or a faulty vehicle electrical component can cause electrical noise, possibly causing unpredictable behavior in printers and docks. Note: If the vehicle voltage is too high or too low, the Intermec equipment may not work. To determine your vehicle's voltage level 1 Measure the vehicle battery voltage with a voltmeter. It should read approximately 13.0 VDC with the engine OFF. For 24 V vehicle systems, check each battery individually. 2 Start the vehicle engine. Continue monitoring the battery's voltage while you run the vehicle's engine at a fast idle for five minutes. The voltage should read below 14.5 VDC. It must not exceed 18.0 V. If the battery voltage exceeds 18.0 VDC, there is a problem with the vehicle electrical system which must be diagnosed and repaired before the Intermec equipment will work properly. Check your engine for a bad voltage regulator or a poor ground, either of which cause excessive voltage. Installing the Power Cable Before installing the power cable, note these installation guidelines: • Choose a mounting location for the Intermec equipment and the cables. Make sure that the mounting location is convenient for the vehicle operator and that the cables will reach from the power source to the equipment. • Use cable clamps or wire-ties to secure cables at least every 46 cm (18 in). 6 Vehicle Power Install Kit Installation Instructions
