ESD is the abbreviation for ElectroStatic Discharge.
ATTENTION
Connector pins or sockets bearing ESD warning labels
must not be contacted or interconnected without ESD
protective measures.
ESD protective measures include:
• Procedures for preventing electrostatic charges
(e.g. via air conditioning, air moistening, conductive
floor coverings and nonsynthetic clothing)
• Discharging the electrostatic charges of your own
body on the frame of the U
wire or large metallic objects
• Connecting yourself to ground using a wrist band.
We therefore recommend that all persons working with
this system be instructed on the significance of this
warning label. Furthermore, they also should receive
training in the physics of electrostatic discharges which
can occur in the practice and the destruction of elec-
tronic components which may result if such components
are contacted by electrostatically charged
The content of this training is specified in Chapter 1.2.
ESD is the abbreviation for ElectroStatic Discharge.
Electrostatic discharge must be preceded by electro-
static charging.
Static electric charges generally occur whenever two
bodies are rubbed against each other, e.g. when walking
(shoe soles against the floor) or driving a car (tires
against the street pavement). The amount of the charge
depends on several factors:
I.e. the charge is higher with a low air humidity than with
a high air humidity and higher with synthetic materials
than with natural materials (clothing, floor coverings).
The following rule of thumb can be applied to gain an
overview of the compensating voltages resulting from an
electrostatic discharge.
An electrostatic discharge is:
• perceptible at 3000V or higher
• audible at 5000V or higher (cracking, crackling)
• visible at 10,000V or higher (arc-over)
