1. Safety instructions
The lamp must not be connected to the mains, until it has been fully assembled and installed.
This device is not suitable for use in hazardous locations.
The devices are not suitable for use in combustible blends of anaesthesia agents with oxygen
or nitrous oxide.
Repairs to the ceiling attachment and special installation work on the sliding contacts should
only be carried out by ourselves or a company expressly authorised by ourselves.
The manufacturer is only responsible for operational safety of the ceiling attachment when
repairs and modifications are carried out by his own staff or by persons who guarantee
compliance with the safety regulations.
The manufacturer is not responsible for damage to persons or property caused by incorrect or
improper use, or when used for incorrect purposes.
General information
These installation instructions must be kept at hand together with the relevant
operating instructions for consultation at any time.
All Dr. Mach lamps are supplied with a flange with
a graduated circle diameter 270mm and six bores
diameter 15mm. The flange supports the vertical
suspension tube. It is attached to the solid ceiling
by means of a ceiling anchorage ring.
Remark: The ceiling anchorage ring has to be
ordered separately!
The ceiling anchorage ring has six precisely
positioned threaded bolts M12. It makes it possible
to fasten and adjust the lamp without causing dust
or dirt after all building work has been completed.
The use of a ceiling anchorage ring is necessary in
all cases of ceiling attachments.
During mounting, take care to ensure that neither
the flange nor the attachment elements are in
contact with reinforcement components of the solid
ceiling.
In view of the slight weight of the Dr. Mach lamps,
it is not fundamentally necessary to drill through
the ceiling and use a counter-plate. Ceiling
anchorage rings can be attached without any
problems to ceilings in the concrete strength class
greater than or equal to B25, using safety dowels
M8.
The forces arising when the widely extending
articulated arms tilt, do make it necessary to drill
very carefully with a certified hammer drill, paying
close attention to the drilling tolerances.
The suspension tube of the lamp must be adjusted
vertically to prevent the lamp body from moving.
For this purpose the M12 counter nuts on the
attaching bolts must be adjusted accordingly.
In case of false ceilings, the suspension tubes for
all lamps can be mounted directly through to the
solid ceiling. The opening required for this purpose
can be closed once the work has been completed,
using the canopy diameter 450mm or a covering
plate.
When using an intermediate flange (preferably for
spaces exceeding 400mm and for room heights
exceeding 4050mm), the length of the intermediate
flange is to be measured to the lower edge of the
false ceiling.
Also in this case a ceiling anchorage ring has to be
used for fixation.

3. Ceiling attachment
3.1 Preparatory work on the ceiling
3.1.1 Setting the safety dowels
Attention:
Lamps, ceiling anchorage rings and intermediate flanges may only be attached to a ceiling of
concrete strength class greater than or equal to B25. In case of light-weight ceiling coverings,
the dowel anchor must be sunk completely into the concrete. To bridge this space use long
threaded bolts for attaching the ceiling tube.
In addition, take care that neither suspension tube nor attaching elements come into contact
with reinforcement components of the solid ceiling.
The lamp weight and the tilt of the long articulated arm(s) require that this work is performed
meticulously. This refers particularly to the use of a certified hammer drill and to observe the
drilling tolerances.
3.1.2 Mounting the ceiling anchorage ring to the solid ceiling
The scope of supply includes:
1 attachment set, consisting of:
• Six safety dowels Fischer FHA 12/50 galZn
• Mounting data Fischer
• Bore template
To attach the ceiling anchorage ring to a solid
ceiling proceed as follows:
• Drill the bore holes according to the figure
diameter 12mm and at least 100mm deep with
a certified hammer drill, using the enclosed
bore template. You can also use the ceiling
anchorage ring as a template. In this case a
second person may be needed to assist.
• Insert the safety dowels through the bores of
the ceiling anchorage ring in such a way, that
the washers lie flat to the ring.
• Tighten the screws carefully using a torque
wrench (25Nm).
Light-weight ceiling panelling with a maximum
thickness of 30mm can be bridged using the
enclosed safety dowels. For panelling thicker than
30mm, it is necessary to remove the panelling
before mounting.

3.2 Pre-assembly of the ceiling flange and suspension tube
and installing the electrical connections
The length of the suspension tube is adjusted to the required room height with a clearance height of at
least 200cm under the lamp.
Aluminium cast flange and suspension tube ∅ 50mm
Standard version
For pre-assembly of ceiling flange and suspension
tube proceed as follows:
• Cable or cord showing out the suspension tube is
to be pushed carefully into the ceiling flange
together with the suspension tube.
• Push the suspension tube upwards until the
safety pin 1 can be pushed through the cross
bores of the suspension tube.
• Then pull the suspension tube down until the
safety pin 1 lies in recess A of the ceiling flange.
• Then secure the connection with six screws 2
and washers 3 to prevent wobbling.
If not possible, turn suspension tube by 180°.
• Pull the cable or cord through the bore 4 as
shown in the diagram.
Attention:
The suspension tube is delivered with
premounted retaining ring for the ceiling
canopy.
Each connection journal is also equipped with:
• 2 spacer rings;
• 1 gib ring;
• 1 circlip (Seegerring).

3.3 Mounting the flange and suspension tube to the ceiling
Before mounting the flange and the suspension tube, assembly work on the ceiling (setting the dowels or
mounting the ceiling anchorage ring and possibly mounting the intermediate flange) must be completed
and all pre-assembly work finished.
Type with ceiling anchorage ring
• Screw three nuts B (each 120°) to the plate of
the ceiling anchorage ring, holding the other
three nuts 0,5cm away from the plate, unscrew
nuts A.
• Position six washers C and six insulating
washers D on the flange.
• Position the flange with suspension tube on the
threaded bolts and adjust it to the required
height using three nuts A and washers C,
insulating washers D, and retaining washers E
(each 120°).
Note: Washers C, insulating washers D and
retaining washers E must be put on the
flange in the same order as shown in the
figure.
• The three-point mounting allows a simple
vertical adjustment of the suspension tube.
Vertical adjustment is very important and
must be carried out with great care.
If the flange with suspension tube is not in the
correct vertical setting, the support arms of the lamp
do not remain precisely in the proper position, they
could turn away and would therefore require
excessive braking.
• Then position from above all six nuts B gently
against the flange.
• Screw on the remaining three nuts A with
washers C, insulating washers D and retaining
washers E and tighten all six nuts equally
cross-wise with a torque wrench (25 Nm).
Note: Washers C, insulating washers D and
retaining washers E must be put on the
flange in the same order as shown in the
figure.
• Verify balance with a spirit-level.

the ceiling anchorage ring, the other three 1cm
away from the plate, unscrew nuts F.
• Position the intermediate flange on the
threaded bolts and adjust it to the required
height using three nuts F and washers H.
• Then position all six nuts G gently against the
intermediate flange from above.
• Screw on the remaining three nuts F with
washers H and tighten all six nuts equally
cross-wise with a torque wrench (25 Nm).
• Verify balance with a spirit-level.
For mounting the flange to the intermediate
flange proceed as described at the design with
ceiling anchorage ring.

4. Electrical connection
4.1 Preparing the electrical connection
Extent of supply:
• Cable on the suspension tube
• Line clamps on the flange
Put the cable through the flange. Ensure that the cables are cut to a length which allows approx. 15cm
cable to extend from the suspension tube.
The flange is fitted with line clamps for connecting the light system to the electrical circuit. These clamps
should be accessible for electrical safety checks during installation and also later.
Connect the mains supply and the cable from the suspension tube to the line clamps.
In case of lamps with external transformer the cross-sections of the cables must be designed in
accordance to the cable-length and power consumption.
The following table shows the recommended cross-sections:
Power consumption
[W]
up to 10 up to 20 up to 40 up to 70
Lead length [m]
80 2,5 4 10 16
Once the electrical connections have been completed, check that the system functions correctly in a noload operation trial run.
When connecting to an external transformer, the emerging voltage U will be approx. 10-20% above rated
voltage because of no load and anticipated lead losses. There is no point in making any adjustments until
the lamps have been completely mounted.
