High-voltage system - General information - Edition 02.2021
Orange-coloured high-voltage cables, e.g. in engine compart‐
ment and on underbody
Note
♦ The electrical wiring of the high-voltage system differs signif‐
icantly from the wiring of the remaining electrical system and
the 12-V system.
♦ Due to the high voltage and current rating the high-voltage
cables have a significantly larger cross section and are con‐
nected via specific contacts. As opposed to the 12-V electri‐
cal system the high-voltage system is not grounded on the
body.
♦ In order to clearly signify the risk resulting from the high
voltage, all cables of the high-voltage system are coloured in
orange.
♦ The high-voltage cables are protected against reverse con‐
nection. They cannot be connected incorrectly since they are
colour-coded and mechanically coded.
♦ Aside from being colour-coded, the components also have
warning labels.
