The wall adaptor has to be mounted in a convenient position on
the
left or right side
of the chair or on the back wall (head of the patient). The useful reach depends on
the length of support arm and cone mounted (source skin distance, SSD).

Risk of falling over

OR THE OPERATOR CAUSING I
N
JURIES.
Wall Support
Mounting options
The wall adaptor can be mounted with
1,
2,
or 3
bolts at top, depending on wall quality, and with 1,
2, or 3 bolts at bottom.
A. Two bolts only (top and bottom central holes
– T2, B2) are used on a solid slim column
(e.g. steel mounting studs) with weak sides
(e.g. wooden wall). The top bolt has to with-
stand a load of 6000 N, comprehensive of the
safety factor, i.e. about 13 0 lbf or 612 kgf.
Proper screw to be selected for a solid connec-
tion to the wall. Classes ISO 8.8 (M 8, M 8x1,
M 8x1.2 ) or SAE Grade ( /16” 18UNC,
/16” 24 UNF) are recommended.
B. Two bolts at top sides (T1, T3) and one or two
at bottom (B1, B2, B3) is the regular mounting
for solid wall (concrete). Each bolt at top has
to withstand a load of 3000 N, comprehensive
of the safety factor, i.e. about 67 lbf or 306
kgf.
On solid concrete use heavy duty metal an-
chors. On hollow bricks use injection chemical
fixing.
C. Three bolts at top (T1, T2, T3) and one or two
at bottom (B1, B2, B3) are required when the
wall is not solid enough and the load has to be
distributed on more points. Each bolt at top has to withstand a load of 2000 N,
comprehensive of the safety factor, i.e. about 4 0 lbf or 204 kgf.
In case the wall is not in condition to withstand the indicat
ed load, corre
c
tive actions
can be evaluated by adoption of reinforcing plates:
D. Large plate to fit vertical supports at 16” distance, with 4 mounting holes and
one cable opening for the wall mount in the middle.
E. In case of a thin (wooden) wall not solid enough, the use of a reinforcing steel
counter plate 2 mm thick can be the solution.
F. The use of two reinforcing steel plates of about 4 times the surface of the wall
adaptor, one by each side of the wall, can help when a single plate is not ade-
quate; additional bolts have to be used to hold together the two plates.

3.3 Electrical connections
3.3.1 Common bolt for earth connection and bonding
•The earth provision is blocked in place first and blocked in place with lock-
washers and a nut tightly secured.
•The bonding conductors are placed next and blocked in place with lock-washer
and nut tightly secured.
Risk of loss of electrical protection.
The role of the lock-washer and the nut tightly secured is to prevent an acciden-
tal loosening of the green-yellow wires in the time, which would compromise the low
impedance, essential for electrical safety.

3.3.3 Wiring the unit with local control
It is here con
sidered the case in which the
power driver and control unit module
(PDCU) is mounted close to the wall adaptor, at one side.
The
mains
power line cable must be connected to the input terminals in the bottom
part of the power driver and control unit (PDCU) module.
The cable to connect to the mains supply line (2 conductors plus earth conductor) is
not provided.
Cables with conductors of larger section have lower electrical resistance and voltage
drop.

3.3.4 Wiring the unit with remote control
It is here considered the case in which t
he power driver and control unit module
(PDCU) is mounted remotely, far from the wall adaptor.
3.3.5 Reduction in length of cable for filament and high voltage supply
In case the cable for filament and high voltage supply needs to be reduced in length,
either the one in the scissor arm or the long extension for remote mounting of the
power module (PDCU), it is recommended to produce the same terminations as
those provided (ring for earth provision of 4 mm diameter and pins for the other
wires) making reference to the following image for wire identification.

3.4 Optional Items
3.4.1 Optional door contact and second enable
A block is available on the PDCU main board for connection of the door contact, to
prevent X-ray radiation with door open.
The unit is provided with two jumpers in place which have to be removed to connect
two door contacts, and conversely they have to stay in place if the two door contacts
are not used. Use one position for a single door contact.
One contact can alternatively be used as second enable for safety reasons.

3.4.3 Optional board for external lights
A.
An optional board to be
mounted on the power
driver module (PDCU) is
available to handle two ex-
ternal warning lights:
a. Connect the board on
connectors J2 and X10.
b. The lights are supplied
at the mains line volt-
age.
c. Use 0 W bulbs maxi-
mum.
d. X-ray unit ON light. It
turns ON when the unit
is powered: use L and R
contacts.
e. X-ray radiation ON. It turns ON
during irradiation:
use L and Y contacts.

3.5 Installation of wall system
3.5.1 Mounting the wall adaptor
A.
Open the
packaging
box paying attention not to da
m-
age the internal items.
Risk of scratching.
Avoid the use of a cutter not to damage the plastic
cover.
B. Take away the plastic cover removing the screw at bot-
tom.
C. Use the Wall Adaptor plate or the drill template to mark
the fixing points.
The Power driver and control unit (PDCU) can be
mounted close to the Wall Adaptor at the right or left
side or in a remote position with connecting cables laid
out accordingly.
D. Make the holes in the wall according to the applicable
type of mounting with one, two, or three bolts at top,
and those at bottom, with or without reinforcing plate.
To be noted that the load is born by the bolts at top.
E.
Mount the metal frame on the wall using pr
o
per heavy
-
duty anchors and make
sure that the cables enter from behind.
F. Secure it to the wall ensuring it is levelled with zero forward-backward and side
deviations.
Risk of unwanted arm drifting.
Improper levelling of the mounting plate causes the arm to swing out of po-
sition.
An uneven wall might require interposing thin inserts (like wide washers) at
the fixing points at top or at bottom, between the wall and the mounting plate,
to assure forward-backward verticality.
Put the level on the front to check
for
forward-backward deviations from verti-
ca
l
ity.
Put the level on the side to check
for
side deviations from verticality.
G.
Perform wire connection and final set
-
up complying with recommended s
e-
quence of actions reported in the following.

FONA XDC – Service and Installation Manual
20/48 69 1 70210 1400409
3.5.2 Mounting the PDCU
A.
Use the mounting plate or the
drill template to
mark the holes on the wall.
B. Take apart the control panel removing the screw
at bottom.
Pay attention when disconnecting the flat ca-
ble of the control panel from the power board.
C. Drill the four holes in the wall and secure the
power and control unit module making sure it is
levelled.
Cabling should have been laid out in accordance to
mounting requirements.
3.5.3 Mounting the Support Arm
A.
Unpack the support arm and check for
integrity
of parts.
B. Remove the rotation end-stop spacer but do not remove the string to pull
the cable of the Scissor Arm to the Wall Adaptor through the Support Arm.
C. Push back the cylinder of the friction not to interfere, lightly grease the shaft of
the extension arm, avoiding to do it in the middle where the friction is acting,
and insert it into the wall adaptor.
D. Mount the rotation end-stop spacer and close the side friction without tightening.
Tuning of side friction to be done when the system is completely mounted.
E. Verify 180° rotation from parking position at one side to the other side.
