Caution! Danger of short circuits
Before working on the onboard power supply, please observe the
relevant manufacturer's instructions!
• Although disconnection of the vehicle’s battery will prevent
short circuits, this may also result in other secondary effects:
– The security code of the vehicle’s radio may be deleted.
– If intelligent systems are installed, their data (like the error
memory of the motor controller) may be deleted.
• Before disconnecting the connection terminals from the battery,
observe the following points:
– Switch off all electrical consumers.
– Separate the minus and plus terminals.
Caution! Danger of fire due to short circuit
Damaged cables can cause short circuits, undesired interferences, or
disturbances.
Please observe the following:
• Always observe the information provided by the vehicle manu-
facturer.
• Lay the lines in such a way that they are not subjected to tensile
or shearing force or pressure.
• Properly fit the cables into place using tape or cable binders.
• Do not route the cable around moving parts. Use rubber sleeves
as protection when feeding a cable through metal or plastic
parts.
• Replace damaged cables immediately!
