Installation Guidelines And Precautions - FLIR PathFindIR II User Manual

3 – Installation
The ECU requires power from the vehicle to operate, and in turn the ECU provides power to the
camera. It is recommended that the ECU should be protected by an in-line fuse and selectively
powered on or off with a switch. The power input requirements are:
The ECU must be properly grounded, as described below. The ECU housing must be grounded to
the vehicle chassis, and the PathFindIR II camera must be isolated from the vehicle chassis. The
optional PathFindIR II Installation Kit provides a means to ground the ECU, and the included camera
bracket, with its non-conductive adjustable ball mount, will isolate the camera as required.
The PathFindIR II must be mounted in a location where it is not obstructed by the windshield or
other glass materials. Although glass is transparent to the human eye, it is opaque in the infrared
spectrum.
It is recommended that power to the monitor should be supplied separately from power to the ECU
to assure clean power (low noise) to both items. Otherwise the video image may appear to have
interference, ghosting, or undesirable video artifacts.

3.3 Installation Guidelines and Precautions

It is generally good practice to bench test the camera prior to permanently installing it in the vehicle.
This will allow the installer to become familiar with all of the components, cables, and connectors.
Do not splice cables or tap into existing cables for power or video. Doing so may result in shock, fire,
or damage to electrical system/equipment. Power connections should be made to the fused side of
the vehicle's power distribution block.
Do not install in areas where the unit will hinder vehicle operation, i.e. radiator, steering, head lamps,
braking systems. Doing so may interfere with the vehicle's operation and cause an accident.
Do not install in areas of high moisture, dust or air intake paths. Doing so may hinder the
performance of the PathFindIR II unit and cause image degradation or window damage.
