3.Beforeinstallation
3.1.Mechanicalspecicationsrequired
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.
Alternativelywerecommendusingthe“FISHER”chemicalwallplugswhichinclude:
•Braidtypeinjectioninsert(itemFIP16X85).
•Threadedbarwithbarandwasher(itemFIP16M,8X110).
•Chemicalxer(itemFIPC150).
3.2.Centralcontrolunitpowersupply
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.Wiringconnectionbetweencentralcontrolunitandgeneratorlight
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.

FigureA
• 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.

• Insert the pin (b) of the extension arm (c) in the hole provided in the wall-mounted plate.
• Take the clutch (a) from the kit, install it on the plate using the corresponding screws and adjust the arm (c) as requi-
red.
FigureC
• Use a spirit level to check that the arm (c) is slightly tilted upwards (approx. 1°). If necessary add a shim to the plate
near the bottom wall plugs (d).
• Fully secure the plate.
FigureD
• If the x-ray unit is installed in one of the corners of the dental surgery, make sure the extension arm cannot rotate too
far (90°) by installing the two end-stop pins (included in the kit) on the x-ray unit itself.
• Find the right position for installing the pair of pins (a,b) and insert them in the holes provided using a hammer.
