Cables can be laid or installed only when the temperature is higher than 0° C (32° F).
Before laying out cables that have been stored in a temperature lower than 0° C (32° F),
move the cables to an environment of the ambient temperature and store them at the
ambient temperature for at least 24 hours.
Handle cables with caution, especially at a low temperature. Do not drop the cables
directly from the vehicle.
As the insulation layer of a cable may age or be damaged at high temperatures, ensure a
sufficient distance between cables and the DC busbars, shunts, and fuses. Cables
prepared by the customer should be flame resistant. No cable should be allowed to pass
through the rear of the air outlet of the cabinet. The air outlet should not be blocked by
any foreign matter.
