4.1.4 Movement and stability of the unit

Fragment: CEREC AC
NOTICE
The unit can overturn or slip away
For reasons of tilt stability, the unit must be pulled by its front handle when being moved. If you push the unit, obstacles on the floor could block its wheels, thus causing it to overturn.
The two front wheels of the unit have brakes which can be locked to ensure secure positioning. If the unit is steeply inclined or standing on a slippery surface and lateral forces are acting on it, it may slide even though the wheel brakes are locked.
➢ Always make sure that the unit's footprint is a flat, nonskid surface.

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.
Lower warning label

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 non­synthetic 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" [ → 17].

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:
bеЦдблЬ
● 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.
62 31 174 D3492 D3492.201.01.17.02 12.2015
Connector pins or sockets bearing ESD warning labels must not be touched or interconnected without ESD protective measures.

Note on wireless communication Data communication between the acquisition unit and the CEREC MC XL

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.

Disturbance of data transmission

Note on wireless communication
grinding unit should preferably be established via the wireless interface (H&W or 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.
Sirona has selected the best possible configuration for data communication via the wireless interface (H&W and 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 CEREC AC is occupied by another plug, remove this wireless interface connection and instead connect the LAN cable with the CEREC MC XL grinding unit.

Network
The acquisition unit may only be operated in a network if it is connected to a HUB/switch. The HUB/switch must:
● be located in the room where the acquisition unit is operated, permanently installed.
● be grounded via an additional ground wire.
Cross-section of the protective ground wire
Modem
At least one of the following specifications must be fulfilled in order to operate the acquisition unit on a modem:
● If a modem is connected, the acquisition unit may only be operated outside of the patient area (radius of 1.5 m surrounding the patient).
● An RS232 isolator compliant with EN 60 601-1-1 with a dielectric strength of at least 1.5 kV must be installed at the modem end in the RS232 connecting cable between the acquisition unit and the modem.

5.3.1 Electromagnetic emission

The UNIT is intended for operation in the electromagnetic environment specified below.
The customer or user of the UNIT should make sure that it is used in such an environment.
Emission measurement Conformity Electromagnetic environment - guidelines
RF emissions according to CISPR 11 Group 1 The UNIT uses RF energy only for its internal
function. Therefore, its RF emissions are very low and are not likely to cause any interference in nearby electronic equipment.
RF emissions according to CISPR 11 Class B The UNIT is intended for use in all facilities,
Harmonics according to IEC 61000-3-2
Voltage fluctuations / flicker according to IEC 61000-3-3
Class A
coincides
including residential areas and in any facilities connected directly to a public power supply providing electricity to buildings used for residential purposes.
