ESD warning labels

CAUTION
Risk of injury or damage to components from electrostatic discharge
For electrical components labeled with an ESD warning label,
observe the following instructions.
➢ Apply the ESD protective measures.
➢ Do not touch connector pins or sockets without applying ESD
protective measures first.
➢ Do not establish any connections between these connectors
without applying ESD protective measures first.
2.4.2 ESD protective measures
ESD stands for ElectroStatic Discharge.
ESD protective measures include:
● Procedures for preventing electrostatic charge build-up (e.g. air
conditioning, air moistening, conductive floor coverings and non-
synthetic clothing)
● Discharging the electrostatic charges of your own body on the frame
of the UNIT, the protective ground 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 electronic
components which may result if such components are touched by
electrostatically charged USERS.
The content of this training is explained in the Chapter "About the
physics of electrostatic charges" [→ 19].
2.4.3

About the physics of electrostatic charges

An electrostatic charge is a voltage field on and in an object (e.g. a
human body) which is protected against conductance to ground
potential by a nonconductive layer (e.g. a shoe sole).
