10 Cabling

10.1 Routing

1. Use caution when routing wires between the passenger and engine compartments to avoid chafing or

pinching the wires. Use grommets over any exposed sharp edges and strain reliefs to keep wires in place. Seal

all holes to prevent moisture intrusion.

2. Route and secure all wiring under the hood away from mechanical hazards such as exhaust manifolds and

moving parts.

3. Avoid running power leads in parallel with vehicle wiring over long distances.

4. If cabling is routed under the instrument panel, be sure that there is no interference with the proper

operation of the foot controls.

10.2 Strain Relief

Ensure that there is no strain exerted on cable connectors where they enter the unit. Avoid placing the unit in a

position where the cable connectors entering the back of the unit are under pressure or strain of any kind.

Ensure the power cable is fully inserted before replacing the cable cover. In the event of undue stress or strain on

installed cables and connectors, permanent damage may occur that can weaken the connections. This may result

in intermittent or complete loss of communication and or power. Always include strain relief every 2-3 feet on

long cable runs.

As the Ranger unit can be tilted and rotated freely by the driver/user, cabling should be installed such that

moving/adjusting the position of the unit does not exert any significant stress on the cables.

10.3 Labeling

It is important to always label cabling at connection points. This practice and using cables with consistent coloring

will make maintenance easier.

10.4 Wire Types

The following are the minimum specifications for the hook-up wire that should be used during the installation

process:

• Ranger Power and Ground

300V, 105°C PVC, 18AWG stranded

• Ignition

300V, 105°C PVC, 22AWG stranded

• Odometer Interface

300V, 105°C PVC, 22AWG stranded

• Ranger Inputs (example: Emergency Input)

300V, 105°C PVC, 22AWG stranded

10.5 Electrical Measurements

Always ensure that there is adequate voltage at the point where Ranger is being powered. Compare this voltage

to the voltage at the battery. The two voltages should be almost the same or a different power point should be

chosen closer to the battery.
