61 35 ... Notes on ESD protection (Electro Static Discharge)

NOTE:

For Special Tool identification, see ENGINE ELECTRICAL SYSTEM - SPECIAL TOOLS - 5-SERIES (E60) .

Special Tools Required: 

NOTE: Electrical components which are particularly sensitive to electrostatic discharge (electronic control units, sensors, etc.) are marked with the ESD warning symbol.

-Electro

-Static

-Discharge

Statically charged persons can discharge by touching electrical components.

NOTE: Humans can only detect a discharge starting from a level of approx. 3000 V.

The danger threshold for electrical components already starts from a level of approx. 100 V.

IMPORTANT: Do not touch pins or multi-pin connectors directly! Touch electrical components by their housings only.
IMPORTANT: To prevent electrical components from being damaged or destroyed by electrostatic discharge, it is absolutely essential to comply with the following instructions:
  • When replacing electrical components, leave the replacement components in their original packaging until immediately before they are to be installed.
  • If necessary, always return a removed component in its original packaging (always pack the component away immediately).
  • Read and comply with user information on using the associated ESD special tool 12 7 060.
