1.6 Laying Out Cables
Binding Signal Cables
Signal cables must be bound separately from strong-current cables and high-voltage cables.
Laying Out Cables
When the temperature is low, a violent strike or vibrations may damage the cable sheathing.
To ensure cable safety, comply with the following requirements:
Cables can be laid, or installed, only when the temperature is higher than 0°C (32°F).
Handle cables with caution, especially at lower temperatures.
Before laying out cables that have been stored in temperatures lower than 0°C (32°F),
move the cables to an environment that is at the requisite ambient temperature. Store
them in this environment for at least 24 hours.
Do not drop the cables directly from the vehicle.
As the insulation layer of a cable may age, or be damaged from high temperatures,
ensure a sufficient distance between cables and the DC busbars, shunts, and fuses.
Cables prepared by the customer should be flame resistant. Cables must not be routed
