NOTES ON ESD PROTECTION (ELECTRO STATIC DISCHARGE)
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.
E -Electro
S -Static
D -Discharge
IMPORTANT: Read and comply without fail with the notes on this subject
from Service
Information 2 06 04 128.
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.
