Mounting Instructions
Follow and retain the mounting instructions included with assembly kit when installing the device. See
Safety on page 17 for safety instructions.
Installing the Device
Electrical Installation
There are various electrical potentials when installing the unit on a vehicle such as a forklift.
24
Installation
WARNING: Most electrically driven forklift vehicles have floating chassis connected to neither DC+ or DC-. However,
electrical faults can cause the battery + or - to be connected to the chassis via low resistance paths. All connected
peripherals must be completely isolated.
The device accepts DC power sources with a minimum of 10 VDC nominal and 48 VDC nominal. A Power Pre-regulator is
required for voltages above 48 VDC nominal.
Applying a voltage above 48 VDC nominal without the pre-regulator or reversing polarity may result in permanent damage
to the device and voids the product warranty.
Figure 7 Ground Lug
Ground Lug
CAUTION: Attach the device connecting cable as close to the battery as possible. Connecting the device to large electrical
loads, such as converters for the forklift motor may result in random restarts, malfunctions and/or irreparable damage to the
device.
To connect devices fed by other power sources to the device, such as printers, power up the peripheral devices at the same
time or after the device to avoid start-up problems, malfunctions or irreparable damage to the device.
Wiring Guidelines
The metal chassis of the device 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, carefully consider the routing of the ground strap 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 catching 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 do 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.
25
Installation
IMPORTANT: Make sure the cables run inside the roll cage of the vehicle.
If the device 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 AC/DC adapter in a permanent installation, the ground lug must be connected to the
ground structure.
Wiring Vehicle Power to the VC8300
WARNING: Applying voltage above the input voltage rating or reversing polarity may result in permanent damage to the
VC8300 and void the product warranty.
An extension power cable is used to wire the VC8300 to the truck battery (order cable separately, see
Accessories on page 120). Wire this cable to a filtered, fused (15A max) accessory supply on the vehicle.
Follow the installation instructions supplied with the extension cable.
Additional wiring (minimum 14 gauge), connectors or disconnects used should be rated for at least 300 VDC,
15A.
When connecting the extension power cable:
•If a power extension cable with ignition sense is used, ensure that the ignition sense wires (18AWG wires in
red and black leads) and the power wires (14AWG in red and black leads) are reliably secured away from
each other, or are separated with reliably secured certified insulation. Minimum 2.8 mm distance, or 0.4 mm
distance through insulation is required for the separation.
•The red lead of the 14AWG power cables attach to the vehicles battery positive terminal. The 14AWG black
lead connects to the vehicle’s battery negative terminal. This should be connected to a proper terminal
block and not to the vehicle body. An optional grounding strap wire (sourced separately) may be connected
to the ground lug of the VC8300 terminal connector bay and to the vehicle chassis.
•You may have the option to connect power before or after the key switch. Though the VC8300 is equipped
with a UPS, a proper shut down is recommended using the Power Off procedure. If it is wired after the key
switch, the operator must shut down the VC8300 using the Power Off procedure before turning off the
vehicle. If it is wired before the key switch, then to avoid excessive drain on the vehicle battery, either the
operator should shut it down when the vehicle is to be left off for an extended period, or the ignition cable
shut down wire should be connected and the VC8300 configured to shut down automatically.
•An appropriate fuse type must be used with the power extension cable according to the installation
instructions. For main power cable, use 3AB, 15A, 250V, slow blow fuse. For ignition sense input, use 3AB,
0.3A, 250V, slow blow fuse.
NOTE: The VC8300 supports the ignition sense feature that detects when the ignition switch or key switch is On or Off to
allow automatic computer start up or shut down (with delay as needed).
When wiring the ignition sense wires (18AWG in red and black), the red 18AWG wire is connected to a positive DC voltage
source switched on by the ignition. The black 18AWG wire is connected to ground reference of this switched ignition source.
External Antenna Installation
To install an external antenna:
1. Align the antenna connector with the connector on top of the VC8300.
2. Insert the antenna connector onto the VC8300 connector.
3. Tighten the antenna connector.

Cable Dust Cover
For the dust cover location, see VC8300 Back View with Dust Cover on page 20.
CAUTION: Turn on external peripheral devices with their own power supply at the same time or after the VC8300. If this is
not possible, ensure that the VC8300 is adequately protected from power leakage caused by an external device.
27
Strain Relief
CAUTION: For safety reasons, install the supplied cable cover for the external ports prior to using the VC8300.
After the VC8300 and bracket are fastened, prepare the strain relief as follows:
1. Install the cables loosely on the strain relief rail (see Figure 4 on page 20).
2. As far as possible, route cables leading to or away from the unit next to one another without crossing.
3. Fasten the cables into the strain relief rail precisely at the positions at which the cable openings in the cable
cover are located.

Forklift Battery Replacement Conditions
The VC8300 maintains normal function of applications and connections during and after forklift battery
replacement.
Replace the forklift battery at any point during a shift and/or while the VC8300 is fully running.
The forklift battery may be replaced under following condition: VC8300 external temperature range: -30° C to
+50° C (-22°F to 122°F).
During forklift battery replacement (VC8300 is running on UPS battery), both Android and the VC8300 are
monitoring remaining UPS battery capacity. The default Low Battery notification threshold is set to 30%. The
Critical Battery threshold is set to 7%. If UPS battery is discharged below 7%, the VC8300 automatically shuts
down.
Starting from Cold Soak
The VC8300 can to start up from a saturated cold soak at -30°C (or above) internal VC8300 temperature when
a valid external DC power source is present.
The VC8300 design minimizes wait time from -30°C cold soak to load the OS and have internal heaters to
assist system warm up.
From a -30°C cold soak condition, the VC8300 battery heater may be activated to warm the UPS battery to an
acceptable charging temperature if charging is needed. The conditions and time to heat the battery are
managed by the system. The OS load time and VC8300 ready for use time is independent of warming the
battery.
29
Installation
Pre-Heat Mode
When the device is powered down or suspended and the system temperature is below -25°C (-13°F), the
device enters pre-heat mode when the user presses the power key. This warms up critical internal components
with the heater elements prior to boot up.
When in Pre-heat mode the Power LED blinks amber.
The pre-heat mode lasts no longer than 15 minutes. The freezer configuration spends less time in Pre-heat
mode due to the additional Touch Panel heater.
The device remains powered down or suspended during Pre-heat mode. Once the system reaches the
adequate temperature, the device automatically boots up. The user is not required to press the power button.
The device does not enter Pre-heat mode if it is outside the operating temperature range (-30°C to 50°C (-22°F
to 122°F)).
Installing the Power Pre-Regulator
IMPORTANT: The Zebra power extension cable positive lead is red and the negative lead is black.
It is recommended that all connections be secured with electrical tape or heat shrink to prevent contaminants from degrading
the connection.
To install the power pre-regulator:
1. Attach the pre-regulator cable male connector to the Zebra power extension cable which is installed on the
vehicle.
2. Connect the pre-regulator cable female connector either directly to the VC8300 power cable, or to the
power extension cable. See Figure 10.
