1. General safety precautions
Cea Sc - Cea Dental Group guarantees the safety, reliability and performance of the equipment under the following
conditions:
- Installation and technical service is performed by authorized technicians using Cea Sc - Cea Dental Group original
spare parts.
- The electrical system in the dental surgery corresponds to standards I.E.C. 60364-7-710;V2 (Standards regarding
electrical systems in a medical environment) or equivalent standards currently in force in the country where the equi-
pment is installed.
- The place where the x-ray unit is installed must comply with ofcial directives regulating radiation in the country where
the equipment is used.
- The equipment is operated as directed in the instructions manual..
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device
may not cause harmful interference, and (2) this device must accept any interference received, including interference
that may cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of
the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications
Changes or modications not expressly approved by the party responsible for compliance could void the user’s autho-
rity to operate the equipment.

3.Beforeinstallation
3.1.Mechanicalspecicationsrequired
If the wall is thin (hollow bricks or similar), use the backplate (part no. 9660048) to be mounted on the wall or placed on
the side of the wall opposite the wall where the unit is to be installed.
Decide on a suitable system for xing the plate according to the characteristics of the wall and its ability to resist a pull
force of 220 Kg applied at each anchorage point.
If the wall is made of cement or solid bricks, use the wall plugs supplied.
Alternativelywerecommendusingthe“FISHER”chemicalwallplugswhichinclude:
•Braidtypeinjectioninsert(itemFIP16X85).
•Threadedbarwithbarandwasher(itemFIP16M,8X110).
•Chemicalxer(itemFIPC150).
3.2.Centralcontrolunitpowersupply
The supply line running to the central control unit must be 3x2.5 mm and protected by a bipolar circuit breaker which
conforms to the relevant electrical codes (10 A, 250 V, breaking power at least 6000 A, distance between contacts at
least 3 mm).
The colour of the three conductors (LINE, NEUTRAL and GROUND) must correspond to that established by regula-
tions.
3.3.Wiringconnectionbetweencentralcontrolunitandgeneratorlight
This connection enables the generator light (optional) located outside the surgery to be turned on.
To connect the LP generator light to the central control unit, use 2 conductors having a cross-section of 0.5 mm (see
paragraph 4.8.).
LP light supply: 230V - 3x2.5 mm line.

The x-ray unit must be installed by a qualied technician in compliance with the installation instructions given below as
regards both the mechanical and electrical parts.
WARNING!
Alwayscheckthatthevoltageindicatedonthegenerator’snameplatecorrespondstothatfortheelectrical
system.

4.2.Wall-mountedplateforsupportingthex-rayunit
FigureA
• Determine the position of the x-ray unit by using the INSTALLATION JIG.(code 97042058).
• First check that the plate is at the correct height and perfectly horizontal and then mark out the four points where it is to be
xed on the wall. Drill the holes and install the most suitable type of fastening system according to the characteristics of the
wall (see paragraph 3.1).
• Pass the supply cable through one of the holes in the wall-mount plate and x this to the wall by partially tightening the
top and bottom screws.
