Specifications
1.1. General Safety Notes
In the Federal Republic of Germany, the electrical installation of rooms used for medical
purposes must conform to the provisions of VDE Standard 0107. Consult installation lay¬
out plan. During installation it is important that all protective ground wire connections
provided by the manufacturer properly made before the equipment is started up. The pro¬
tective ground wires between the individual system components and the power supply
are connected as shown in the wiring diagram. Regulations of professional associations
concerning safety and accident prevention must be observed. No work may be performed
on parts carrying a voltage higher than 42V (Peak Voltage). If it is necessary to turn on the
power for execution of movements of the equipment in the mode of installation procedure,
it must be shut down immediately after completion of these movements.

2 . Mounting of Unit
2.1 Site Preparation
Make unit site preparation according to dimensional drawing on page 5.The bore diameter
must be 12 mm. To assure all movements of the equipment pay attention to all movement
possibilities.
Note: The mounting points must be suitable for tensile strength of 1000 N pull.
For example: Liebig-safety bolts SI 2/65 for concrete floor tensile strength classification DIN
1045 B 15.
2.2 Uncrating
Remove top and side walls of the crate (not necessary with just protection packing). Take
out the Bucky support and accessories and unpack completely. Check the contents of each
box with dispatch note or order to assure that all items are located. Pay also attention to
page 10 1.13 Component check list.
Fig. 1 Fig. 2
Mount low voltage unit (Fig. 27) onto the rope return block with the four stay bolts.
Move equipment with the transport palette to the installation place and assure that foot end
of the palette is approx. 1,5 m away from the installation wall.

(Factory adjustment and field change activity)
3.1 B ucky Tilt Adjustment
Put the swivel arm in upright position, so that the Bucky is at the bottom. Loosen lock
(Fig.10/ Pos. 42) and determine weight difference with means of a spring scale of the
Bucky angulation. In case of weight differences: remove Bucky and compensate
weight difference with trim weights. Reinstall Bucky.
3.2 A djustment of Rotation
Put swivel arm in horizontal position, remove cover (Fig. 11/Pos. 29 and 31), ad¬
just weight difference with trim weights (Fig. 11/Pos. 37) in tube support.
3.3 A d justment of vertical carriage
Release vertical brake and fasten weight balance with spring scale. Drive vertical carriage
downwards (mid of travel way) until the sleeve of the counterbalance is at the same height
as the bore hole in the column stand for the support bolts and put support bolts
(Fig. 18/Pos. 1) through column.
Remove cap (Fig. 8/Pos. 18) from column stand and the strip (Pos. 19) from weight case.
Attention: Danger when the support bolt (Fig. 18/Pos. 1) is not properly placed in
the column.

Switch off power supply. Adjust weight difference with weight plates and insert in counter¬
weight box. Install security sleeve (Fig. 8/Pos. 19) onto counterweight box and lock column
with cap (Pos. 18).
Remove support bolt (Fig. 18/Pos. 1) from column.
3.4 A djustment of Rotational Lock
Remove the left and the right trim cover (Fig. 18/Pos. 2+3) of the vertical carriage.
Loosen counter screws (Fig. 19/Pos. 67). Turn adjusting nut (Pos. 68) clockwise for more
lock holding force. Tighten counter screw (Pos. 67) again.
Note:
The brake lever (Pos. 69) should be parallel to the edge of the vertical carriage. If neces¬
sary change position of lock screw (Pos. 71) and counter lock it with nut (Pos. 72) again.
