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

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2010 BMW 528xi, 2010 BMW 528i, 2009 BMW 528xi, 2009 BMW 528i, and 2008 BMW 528xi. However, it is still accessible from the selected car via links, so may be relevant.

Special tools required:

12 7 060

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

E-Electro

S-Static

D-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 special tool 12 7 060

Personal protective equipment:

Electrically conducting clothing (high wool content, antistatic shoes required).

These can primarily be identified by the ESD logo on the side.
