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.
The ESD warning label must be attached to the coupling box connector
pins.
4.3.2 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".
4.3.3

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).
Electrostatic charges generally build up whenever two bodies are rubbed
against each other, e.g. when walking (shoe soles against the floor) or
driving a vehicle (tires against the street pavement).
