4.1 Basic safety information
4.1.1 Prerequisites
NOTE
Important information on building installation
In order to prevent the risk of an electric shock, this unit must only be
connected to a supply mains with a ground wire.
The building installation must be performed by a qualified expert in
compliance with the national regulations.
NOTE
Restrictions regarding installation site
The system is not intended for operation in areas subject to explosion
hazards.
NOTE
Do not damage the unit!
The unit can be damaged if opened improperly.
It is expressly prohibited to open the unit with tools!
4.1.2 Connecting the unit
Perform connection by following the directions given in the present
operating instructions.
4.1.3 General safety information
CAUTION
Do not damage the monitor
DO NOT touch the LCD screen with sharp or pointed objects.
If the LCD monitor is damaged (e.g. the glass screen is broken),
prevent any leaking liquid from coming into contact with your skin,
mucous membranes (eyes, mouth), or foodstuffs and be careful not to
inhale any escaping vapors.
Rinse any parts of your body or items of clothing already

4.3.1 ESD warning labels
ESD warning label 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.
4.3.2 ESD protective measures
ESD ESD stands for ElectroStatic Discharge.
ESD protective measures 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.
Training 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].

4.3.3 About the physics of electrostatic charges
What is an electrostatic charge? 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).
Formation of an electrostatic charge 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).
Amount of charge The amount of charge depends on several factors:
Thus the charge is higher in an environment with low air humidity than
in one with high air humidity; it is also higher with synthetic materials
than with natural materials (clothing, floor coverings).
Electrostatic discharge must be preceded by electrostatic charging.
The following rule of thumb can be applied to assess the transient
voltages resulting from an electrostatic discharge.
An electrostatic discharge is:
● perceptible at 3,000 V or higher
● audible at 5,000 V or higher (cracking, crackling)
● visible at 10,000 V or higher (arc-over)
The transient currents resulting from these discharges have a
magnitude of 10 amperes. They are not hazardous for humans because
they last for only several nanoseconds.
Background Integrated circuits (logical circuits and microprocessors) are used to
implement a wide variety of functions in dental/X-ray/CAD/CAM
systems.
The circuits must be miniaturized to a very high degree in order to
include as many functions as possible on these chips. This leads to
structure thicknesses as low as a few ten thousandths of a millimeter.
It is obvious that integrated circuits which are connected to plugs
leading outside of the unit via cables are sensitive to electrostatic
discharge.
Even voltages which are imperceptible to the user can cause
breakdown of the structures, thus leading to a discharge current which
melts the chip in the affected areas. Damage to individual integrated
circuits may cause malfunction or failure of the system.
To prevent this from happening, the ESD warning label next to the plug
warns of this hazard. ESD stands for ElectroStatic Discharge.
Connector pins or sockets bearing ESD warning labels must not be
touched or interconnected without ESD protective measures.

D3492.201.06.35.0209.2019
4.4 Wireless phone interference with equipment
The use of mobile wireless phones in practice or hospital environments
must be prohibited to ensure safe operation of the unit.
4.5 Disturbance of data transmission
Note on wireless communication Data communication between the acquisition unit and the CEREC MC
XL production unit should preferably be established via the wireless
interface CEREC Radio Device or WLAN.
As for all wireless connections (e.g. cell phones), heavy utilization of the
available radio channels or shielding caused by building installations
(e.g. metal-shielded X-ray enclosures) may impair the quality of the
connection. This may become noticeable through a reduction in range
and/or a slower data transmission rate. In extreme cases, it will be
impossible to establish a wireless connection at all.
Dentsply Sirona has selected the best possible configuration for data
communication via the wireless interface (CEREC Radio Device) or
WLAN, which generally ensures perfect functioning of this connection.
However, in individual cases unrestricted wireless data communication
may be impossible for the reasons mentioned above and/or due to local
circumstances. In such cases, a cable LAN connection should be
selected to ensure uninterrupted operation. If the only LAN interface on
the rear of the acquisition unit is occupied by another plug, remove this
wireless interface connection and instead connect the LAN cable with
the CEREC MC XL production unit.
