SERVICING THE XVISION
®
SYSTEM
The following sections provide instructions for maintaining
and/or replacing components of the XVision
® system.
CAMERA MOUNTING BRACKET REPLACEMENT
1. Loosen and remove the four 5/16 in. bolts securing the
IR camera bracket to the mounting bracket.
2. Disconnect the camera harnesses (2-pin and 6-pin).
Remove the IR camera assembly.
3. From inside the cab, remove all mounting hardware from
the mounting bracket.
4. Remove the stud plates, mounting bracket, and shims
(if used).
5. Clean the area around the drilled holes in the cab.
6. Align the new mounting bracket with the holes in the
cab. Note: use new mounting hardware for the
installation.

ELECTRICAL SYSTEM
POWER AND GROUND (POWER INPUTS)
Electrical power to the XVision ® system is provided through
the vehicle harness. The vehicle ignition wire {(A) Red} should
be fused to a 3 A slow open fuse (maximum) and connected
to the ignition bus of the vehicle. The ground wire {(B) black}
should be connected to the ground bus of the vehicle. The
headlamp active wire {(C) blue} should be fused to a 1 A fast
open fuse (maximum) and connected to the vehicle headlamp
circuit. When the headlamps are on, 12 V should be present
on the blue wire.
WARNING: Vehicle power and headlight circuits MUST
be fused. Permanent damage to the display, IR
camera, or vehicle electrical system could occur if
power to these units is not fused. Eliminating fuses
from circuit will void all warranties.
IMPORTANT: When replacing a fuse, it is important
to use only the specified fuse with the correct
amperage, as listed above. The use of a fuse with a
rating other than indicated may result in a dangerous
electrical system overload. Repeated opening of a
properly rated fuse indicates a problem in the circuit
that must be corrected.
OPERATING INPUT VOLTAGE
The IR camera is operational in the temperature range
between -40°C to 60°C. Normally, the IR camera takes about
45 seconds to warm up. However, as the external
temperature gets closer to the extremes listed, the warm-
up time will begin to approach two minutes. Refer to Figure
19.
The IR camera and display are compatible with 12 V DC
battery systems with a chassis ground.
