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.

-Electro

-Static

-Discharge

Statically charged persons can discharge themselves when they tap 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.

Only tap the housings of electrical components.

IMPORTANT: To avoid damaging or destroying electrical components as a result of electrostatic discharge, it is absolutely essential to observe the following instructions:

Personal protective equipment: 

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

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