5.7 VH10 Vehicle Installation
5.7.1 Wiring Guidelines
The metal chassis of the VH10 is equipped with a ground lug (located on the underside adjacent to the
power cable) to provide additional ground to the vehicle. It is strongly recommended that a grounding strap
is used to connect the ground stud on the vehicle-mount to a solid, reliable contact point on the main
portion of the vehicle chassis. It must not be connected to battery negative or terminal block.
As with other vehicle cables, the routing of the ground strap should be carefully considered to ensure it
does not pose a hazard to the operator or the safe operation of the vehicle. If necessary, secure the ground
strap with cable ties or some other mechanical means to prevent loops or loose lengths of wire from catch-
ing on stationary items when the vehicle is in motion.
Before installing the cables between the mount and other devices, consider the following:
• Ensure that drilling holes will not damage the vehicle or its wiring.
• Protect cable runs from pinching, overheating and physical damage.
• Use grommets to protect cables that pass through metal.
• Use plastic straps and tie-downs to secure cables and connectors in their desired location, away from
areas where they may get snagged or pulled.
• Keep cables away from heat sources, grease, battery acid and other potential hazards.
• Keep cables away from control pedals and other moving parts that may damage the cables or interfere
with the operation of the vehicle.
5.7.2 Non-Vehicle Installations
Using AC power, the VH10 Vehicle-Mount Computer can be mounted at fixed locations adjacent to
cross-dock doors, manufacturing stations, or in offices.
The 100/240VAC Power Supply Model PS1450 should be used to power the computer from an AC source.
5.7.3 Wiring Vehicle Power to the VH10
A 1.8 meter (6 ft.) power extension cable (Model CA1210) is supplied with your VH10. This cable should be
wired to a filtered, fused (maximum 10A) accessory supply on the vehicle. When connecting a power
pre-regulator to a vehicle, please follow the instructions in the installation sheet supplied with the
extension cable.
Important: Do not carry the vehicle-mount computer by the power input cable.
Important: Make sure the cables run inside the roll cage of the vehicle.
Important: If the VH10 is installed in an environment where earth ground is present such as a
vehicle with metal wheels running on a metal track, OR is powered by the PS1450
AC/DC adaptor in a permanent installation, the ground lug MUST be connected to
the ground structure.
Important: The AC/DC power supply is only intended for use at the room temperature of a
typical office environment.
Warning: The VH10 accepts DC power sources between a minimum of 10VDC nominal and a
maximum of 48VDC nominal. A Power Pre-regulator is required for voltages above
48VDC.
Applying a voltage above 48VDC without the pre-regulator or reversing polarity may
result in permanent damage to the VH10 and will void the product warranty.
