Teklogix 8570 Vehicle-Mount Computer User Manual 61
Chapter 4: Installation
Power Options
4.2.8.1 Non-Vehicle Installation
Using AC power, the 8570 Vehicle-Mount Computer can be mounted at fixed
locations adjacent to cross-dock doors, manufacturing stations, or in offices. The
universal 120/240 VAC power supply (PN 19894) should be used to power the
computer from an AC source.
4.2.8.2 Installing The Pre-regulator
The Pre-regulator should be used on all vehicles that run off voltages greater than
12 VDC nom. This helps to eliminate power irregularities that may affect the
computer’s operating system.
Warning: The Pre-regulator is required on all electrical vehicles (non-engine
driven) since the 8570 has a grounded (non-isolated) chassis.
Install the Pre-regulator to the vehicle using the appropriate hardware, listed below.
See Figure 4.11 on page 62 for a cable diagram.
1. PN 19893-400 10-55 VDC in: 36 watts 18V out
Note: --400 should be installed on 12V trucks that require that the terminal be
isolated from the truck power supply.
PN 19893 55-90 VDC in: 50 watts 15V out
PN 19893-600 15-55 VDC in: 36 watts 18V out
2. Connect the DC output power cable to the 8570.
3. Next, connect the Extension Power Cable PN 13985 to the vehicle as
per the instruction sheet supplied with the cable.
Important:
1. The Teklogix Extension Power Cable PN 13985 positive lead is red
and the negative lead is black.
2. It is recommended that all connections be secured with electrical
tape or heat shrink to prevent contaminants from degrading the
connection.
3. Water will not harm the Pre-regulator and Transient Suppressor if the
Pre-regulator is mounted vertically, with the mounting flange face-
down, so that water cannot pool in the upper case. The power module
inside the unit is sealed. If mounted properly, any water will drain
out of the unit and will not harm the power supply inside.
