imum weight of equipment attached to it, must be taken into account.
Note:
Dimension (A) must not exceed 800 mm (31.5"). Otherwise, a ceiling sub-
structure must be installed to bridge the excess distance. When designing
the substructure, make sure it is strong enough to withstand the bending
vibrations caused by the arms of the ceiling mount.

 12 New installation of S8 / S 81 ceiling mount

Installation position in the OR

The optimum installation position of the ceiling anchor plate is dependent

on the required position of the operating table in the OR. The following
overview shows the ceiling mounts in their optimum operating positions.
We recommend installing the ceiling anchor plate above the area of the
patients' feet.
Alternatively, the ceiling anchor plate can be installed laterally to the op-
erating table. Please see the illustration for the recommended distances
of the ceiling anchor plate from the surgical field.
In unfavorable on-site conditions, it may not be possible to implement the
installation in the recommended positions. Installation options for
cramped conditions are shown from page 16 onwards. OR illuminators
can only be used with restrictions or not at all in this case.

On-site preparations

Customer's responsibilities

Note:
Zeiss service staff can install the ceiling mount only if all points of the fol-
lowing checklist applicable to the relevant installation conditions have
been fulfilled.

The actual load on the ceiling depends on a large number of different fac-
tors, which must be determined in detail by a structural engineer on a
case-to-case basis: see "Constructional requirements for ceiling mounts"
on page 29.
Caution:
g Make sure that a structural engineer checks the installation conditions
during the planning procedure.
Structural verification must be performed prior to the installation of the
mount.
We recommend filing the structural verification in the ceiling mount
documentation.
g Obtain a written confirmation from a structural engineer stating that
the applicable national codes and regulations have been complied
with.
g Please add a copy of the "Confirmation of structural calculation" to
your order (see page 47).
g If any differences exist between the planning documents and the ac-
tual on-site situation, please inform your contact at Carl Zeiss or the
planning expert prior to the installation of the pre-installation set.
g The system should be installed on a hard, level surface, e.g. concrete.
Do not countersink the pre-installation set, but mount it directly on the
respective surface.
g On-site conditions also include building vibrations, which the structural
engineer responsible must take into account right during the planning
phase (see page 26).
Obtain a written confirmation from your structural engineer stating that
possible building vibrations have been taken into account (see page
47).

Warning!
g If an existing ceiling anchor plate or intermediate piece must be ex-
changed, never re-use the old anchors. New anchor holes must be
drilled.
When calculating the effective strength of the new anchors, the struc-
tural engineer must take into account the weakening effect of the old
holes in the ceiling.

Planning the installation

g Inspect the mounting components supplied for completeness and
damage.
g Prior to the installation of a ceiling mount, you must always check that
the actual installation conditions - in particular the room height - corre-
spond to the specifications in the drawing.
g Make sure that the anchors calculated by your structural engineer are
properly installed, that the nuts and washers required to mount the
ceiling anchor plate are readily available at the installation site and
that the maximum tightening torque for the nuts is indicated.
g For new installation, the pre-installation set must be mounted before
the false ceiling is attached.
g At least 2 installers are required for mounting the pre-installation set.
g Installation of a ceiling mount in rooms with an air supply ceiling re-
quires proper preparation of the air supply ceiling (see page 30).

 26 New installation of S8 / S 81 ceiling mount

Building vibrations

The on-site requirements also include the low-vibration design of the

ceiling in the OR. This must be taken into account right during the plan-
ning phase for the ceiling mount.
The following information primarily refers to the ceiling mount, but it can
also be applied to a wall mount or floor stand.
Two types of excitation factors must be distinguished:
Single events which excite short-term vibration
Induced by inadvertent knocks against the suspension system or strong
impact against ceiling, wall or floor. This is the most frequent, but least
critical type of excitation. The ZEISS ceiling mount features excellent
damping against this type of vibration and displays a short recovery time.
In extreme cases, surgery has to be interrupted for a few moments.
Constant excitation causing sustained vibration
The excitation energy of factors such as elevators, air conditioning sys-
tems, construction work, traffic does not easily reach the ceiling mount via
the building. This type of excitation is extremely rare, but may lead to per-
manent vibration of the ceiling mount in extreme cases. This becomes
particularly visible at high magnifications as used in the surgical micro-
scope.
The following result of a study is intended to help you understand constant
vibration excitation occurring in rare cases in ceiling mounts, eliminate it
or prevent it from the outset in new installations.
Like any kinematic system, the Zeiss ceiling mount displays eigenfre-
quencies (=resonance frequencies) that range between 2 and 80 Hz de-
pending on the position of the system and the accessories attached to it.
The ZEISS ceiling mount provides very effective damping in particular
against higher frequencies above 10 Hz which are typical of buildings with
electrical excitation factors. Nevertheless it may happen in rare cases,
when the ceiling mount's suspension arm is in a specific position, that
even high frequencies which are critical for this particular constellation
lead to vibrations (e.g.: 17 Hz, ..., 19 Hz, ...).
Such excitation factors can usually be suppressed by the following meas-
ures:
e elimination of the excitation source (e.g. repair or damping of the air
conditioning system)
e constructional damping measures in the ceiling installation

Due to the large number of parameters involved and the variety of poten-
tial building/ceiling mount constellations, Carl Zeiss Surgical is unable to
give an absolute guarantee for the vibration-free suspension of the ceiling
mount, even if the building meets the applicable ISO standards.
However, it is highly improbable that constant vibrations are transferred
to the ceiling mount if all requirements regarding vibrations in the OR
ceiling are met.
e Max. vibration velocity (RMS) at the installation points for the ceiling
mount.
e Vmax < 0.1 mm / s or Vmax < 4 milli-inches / s or below the curves (di-
agram) for the specified frequency range.

Constructional requirements

The actual load on the ceiling depends on a large number of different fac-
tors. The requirements to be met by the ceiling or substructure result from
the addition of perpendicular forces and torques produced by the suspen-
sion system and accessories. These are the forces to be transmitted into
the structural ceiling via the ceiling anchors.
The column must be aligned in a vertical position (max. deviation ± 0.5°).

Forces and torques

Warning!
The structural engineer must ensure in each individual case that the struc-
tural ceiling has a sufficient load capacity for the forces and torques listed
below. He must also take into account any additional loads on the ceiling
and add an appropriate safety margin, and must observe the applicable
national codes and regulations.
Caution:
e The perpendicular forces and torques specified below include an ad-
ditional load of 100 kg (220 lb), which is generated when a person
hangs on the end of the suspension arm (or the microscope). Further
safety margins have not been incorporated.
e The perpendicular forces and torques have been calculated on the ba-
sis of the maximum permissible load on the suspension arm.

S8 or S81 ceiling mount

For an S8 or S81 ceiling mount alone (without accessories on the acces-
sory interface), the structural ceiling must have the following load ca-
pacity:

e Perpendicular force: minimum 2500 N (565 lbf)

e Torque: minimum 3000 Nm (2215 lbf.ft)

Mounting a pre-installation set on ceilings with air-supply ceiling

Caution:
If the carrier arm systems are installed in air-supply ceilings, the method
of installation must be specifically adapted to the constructional features
of the type of air-supply ceiling involved.
A false ceiling set is mounted to bridge the distance between the struc-
tural ceiling and the non-structural false ceiling. The length of the stud
bolts and spacers used is adapted on site as required.
The necessary planning should be performed in consultation with the
manufacturer of the air-supply ceiling and Carl Zeiss.
When ordering, please specify distance (A), i.e. the distance between the
lower surface of the structural ceiling and the lower surface of the false
ceiling.
Note:
e Distance (A) is the height of the false ceiling and must not exceed
800 mm. Otherwise, a ceiling substructure must be installed to bridge
the excess distance. Distance (Z) is the height of the air-supply ceiling.
e It is essential that the false ceiling set (2,3) and the conduits for the
power lines be installed before the air-supply ceiling is attached. Sub-
sequent installation is not possible, for reasons of space.
e A manhole (5) which is free from compressed air must be available for
the installation work. The internal diameter (S) of the manhole must be
larger than that of the opening in the ceiling (M).
e The opening of the manhole to the OR can be closed with a separate
cover (7) by the manufacturer of the air-supply ceiling.

Planning the electrical installation

The power lines on the site of installation must be run up to the interface
plate. In addition, the potential equalization lines must be run to the termi-
nals on the interface plate.
Warning!
e The planning, execution and inspection of the on-site electrical instal-
lations must be performed by expert electrical technicians and official-
ly registered electrical firms.
e The electrical installations of the room concerned must comply with
the requirements of the applicable national regulations. In the Federal
Republic of Germany, VDE 0107 applies.
e The number of circuits is dependent on the customer's specific carrier
system configuration.
e If several circuits are required by the customer, appropriate allowance
must be made on the interface plate.
e Multiwire lines must be provided with wire end sleeves.

Note:
Please note that the relevant dimensions have to be entered in the fol-
lowing drawing for each purchase order.
g Enter the data and enclose a copy of the drawing with your purchase
order.
Caution:
Use the following principle for planning the installation of the S81 ceiling
mount: Keep the ordered length (A) of the pre-installation set as short as
possible and select a longer column length (D) as required.
C Required distance from floor
We recommend defining different distances from the floor, depending
on the application involved: ENT 1650 mm (65"), ophthalmology
1800 mm (70.9"), reconstructive and plastic surgery 1800 mm (70.9"),
others 1650 mm (65").
H Room height (distance from the floor to the structural ceiling)
g You must exactly measure this height.
A Ordered height of pre-installation set
Start your planning using the shortest length of 200 mm (7.9").
D Column length (ordered length)
Calculate the column length: D = H - A - C - 810 mm (-31.9").
The column length may be a minimum of 40 mm (1.6") and a maxi-
mum of 800 mm (31.5").
Note: column lengths of >600 mm (>23.6T)
Depending on the type of construction involved, vibrations may have
a negative influence if the column length (D) exceeds 600 mm
(>23.6t).
g Use column lengths of >600 mm (>23.6t) only in exceptional cases. If
on-site conditions permit it, column lengths of >600 mm (>23.6t) can
be avoided by selecting an appropriately greater height (A) of the pre-
installation set.
Example: Use the maximum column length (D) of 600 mm (23.6") and
calculate the length (A) of the pre-installation set to be ordered using
the formula: A = H - D - C - 810 mm (-31.9").
F Length to which cover (F) (1139-023) must be cut
Calculate length (F) to which the cover must be cut:
F = A - 7 mm (-0.3").

Accessory interface

Next to the flange area for the carrier arm of the ceiling mount, the mount
flange also features a flange area for an accessory carrier. This is the ac-
cessory interface designed as a hole circle, see page 66.
This accessory interface permits you to mount an accessory carrier e.g.
for OR illuminators, supports, monitor brackets, trays for video systems or
similar devices.

Coupling of the Zeiss system with accessories from other manufacturers

Caution:
The coupling of a system from Carl Zeiss Surgical GmbH with accesso-
ries (OR illuminators, monitor brackets or similar) from other manufac-
turers results in a new medical system for which the creator of the new
system must meet the necessary requirements (approval, qualification,
structural requirements, etc.).
Please note the user manuals provided by the manufacturer of the acces-
sory modules. Further information is available from our service depart-
ment or from authorized representatives.
g Check the feasibility of the installation in detail together with the man-
ufacturer of the relevant accessory module (OR illuminator or monitor
bracket).

Mount flange and ceiling panel

The S8 or S81 ceiling mount is secured with mount flange (1) on the pre-
installation set already installed in the ceiling. In addition to the flange
area for the carrier arm of the ceiling mount, the mount flange also fea-
tures a flange area for an accessory carrier e.g. for attaching an OR illu-
minator and/or monitor bracket. The mount flange is part of the ceiling
mount and is included in its delivery package.
Ceiling panel (2) is used to cover the mount flange and the entire opening
in the false ceiling. The opening in the false ceiling must not be larger than
600 mm x 600 mm (23.6" x 23.6"). Two openings are provided in the
ceiling panel, one for the ceiling mount and one for an accessory carrier.
Cover frame (3) closes the remaining space between the square tube of
the ceiling mount and the ceiling panel.
Blind cover (4) is supplied together with the ceiling panel, permitting the
opening for the accessory carrier to be completely closed. You can make
an opening in blind cover (4) which fits the accessory carrier used.
A dummy cover is available for closing the opening in the false ceiling until
the ceiling mount is installed. Also see page 48 and page 52.
Note:
The S8 or S81 ceiling mount is delivered with the following components
already mounted: mount flange (1), cover frame (2) and carrier arm of the
ceiling mount (5), as in the configuration example on page 67.

Customer's responsibilities

Note:
Zeiss service staff can install the ceiling mount only if all points of the fol-
lowing checklist applicable to the relevant installation conditions have
been fulfilled.

The actual load on the ceiling depends on a large number of different fac-
tors, which must be determined in detail by a structural engineer on a
case-to-case basis: see "Constructional requirements for ceiling mounts"
on page 29.
Caution:
g Your structural engineer must separately take into account the addi-
tional perpendicular force and additional torque produced by accesso-
ries mounted on the accessory interface, i.e. he must add them to the
perpendicular force and torque caused on the ceiling by the ceiling
mount alone.
g Make sure that a structural engineer checks the installation conditions
during the planning procedure.
Structural verification must be performed prior to the installation of the
mount.
We recommend filing the structural verification in the ceiling mount
documentation.
g Obtain a written confirmation from a structural engineer stating that
the applicable national codes and regulations have been complied
with.
g Please add a copy of the "Confirmation of structural calculation" to
your order (see page 73).
g If any differences exist between the planning documents and the ac-
tual on-site situation, please inform your contact at Carl Zeiss or the
planning expert prior to the installation of the pre-installation set.
g On-site conditions also include building vibrations, which the structural
engineer responsible must take into account right during the planning
phase (see page 26).
Obtain a written confirmation from your structural engineer stating that
possible building vibrations have been taken into account (see page
73).

Forces and torques

Warning!
The structural engineer must ensure in each individual case that the struc-
tural ceiling has a sufficient load capacity for the forces and torques listed
below. He must also take into account any additional loads on the ceiling
and add an appropriate safety margin, and must observe the applicable
national codes and regulations.
Note:
The maximum permissible perpendicular force and the maximum permis-
sible torque for the accessory interface result from the difference between
the maximum permissible values for the pre-installation set and ceiling
mount, i.e. pre-installation set - ceiling mount = accessory interface.
Pre-installation set
The pre-installation set can accept the following maximum perpendicular
force and maximum torque:

e Perpendicular force: max. 6200 N (min. 1393 lbf)

e Torque: max. 9500 Nm (max. 7007 lbf.ft)

Since the pre-installation set is subjected to the following maximum per-

pendicular force and maximum torque by the ceiling mount:

e perpendicular force: min. 2500 N (min. 565 lbf)

e torque: min. 3000 Nm (min. 2215 lbf.ft)

the following maximum perpendicular force and maximum torque remain

for the accessories:
Accessory interface (maximum)

h Perpendicular force: max. 3700 N (max. 832 lbf)

h Torque: max. 6500 Nm (max. 4794 lbf.ft)

Electrical connections for accessory modules

The power supply for the electrical accessory components can be con-
nected to connectors "A" on the interface plate (connectors for OR illumi-
nators, terminal blocks B and C).

On-site requirements for the connection of accessories

g Route the power lines in the building up to the interface plate.
g Route any required control lines and/or monitor connections in the
building up to the interface plate.
g Make sure (for in-wall installation) that a sufficient number of conduits
with sufficient cross section are provided.
g Route additional lines for potential equalization to the terminals on the
interface plate.
Warning!
e The planning, execution and inspection of the on-site electrical instal-
lations must be performed by expert electrical technicians and official-
ly registered electrical firms.
e The electrical installations of the room concerned must comply with
the requirements of the applicable national regulations. In the Federal
Republic of Germany, VDE 0107 applies.
e The number of circuits is dependent on the customer's specific carrier
system configuration.
e If several circuits are required by the customer, appropriate allowance
must be made on the interface plate.
e Multiwire lines must be provided with wire end sleeves.

 76 Discipline-specific installation positions

The various surgical disciplines and on-site conditions require different in-
stallation positions of the S8 and S81 ceiling mounts.
This chapter describes a number of recommended installation positions
of the S8 and S81 ceiling mounts for different surgical disciplines.
Note:
In unfavorable on-site conditions, the recommended installation positions
must be changed appropriately. In cramped conditions, the use of OR il-
luminators is only possible with restrictions or indeed not at all.
Caution:
The recommended discipline-specific installation positions do not release
you from the responsibility of careful planning. Only careful planning will
ensure a smooth, collision-free workflow during surgery.

Scale 1:20
All recommended, discipline-specific installation positions are shown at a
scale of 1:20 and can usually be directly incorporated in the layout plan.

Transparent film
It may also be helpful for your planning work if you copy the scale 1:20
discipline-specific installation positions to transparent film. You can then
place the transparent film on the layout plan, and bring it into a suitable
position by shifting and turning it.
Note:
In the following illustrations, the representation of the ceiling mount in light
gray, dotted lines shows the alternative, mirrored (laterally reversed) in-
stallation option.

 Discipline-specific installation positions 77

Installation positions for ophthalmology and ENT

The S8 or S81 ceiling mount is used for ophthalmology and ENT.

Recommendations for ophthalmology

Preferred installation position for ophthalmology
The S8 or S81 ceiling mount is positioned above the patient's foot area
(centered relative to the operating table).
Alternative installation position for ophthalmology
The S8 or S81 ceiling mount is positioned laterally to the patient (centered
relative to the patient's head).

Recommendation for ENT

General
Two OR illuminators are normally used for ENT. Do not mount these OR
illuminators (ceiling lights) on the mount flange of the ceiling mount, but
on separate ceiling flanges. Otherwise, collisions are liable to occur if both
ceiling lights are pointed at the surgical field at an angle from behind the
surgeon.
Preferred installation position for ENT
The S8 or S81 ceiling mount is centered above the operating table.
The OR illuminators are not mounted on the flange of the ceiling mount,
but on separate ceiling flanges.
Alternative installation position for ENT
The S8 or S81 ceiling mount is installed in a centered position behind the
patient's head.
Again, the OR illuminators are not mounted on the flange of the ceiling
mount, but on separate ceiling flanges.

Installation position for P&R, Hand

The S8 ceiling mount is used for P&R and hand surgery.

The installation positions recommended in this chapter are also suitable
for the following applications:
e ENT
e Neurology
e Urology
e Oral and maxillofacial
e Spine (limited suitability).

Note:
In P&R surgery, one or the other of the patient's hand may sometimes be
difficult to reach. In such cases, there is usually the possibility of turning
the operating table in such a way that the hand concerned is brought
within the optimum working range of the ceiling mount.

 Installation on an existing substructure 99

Installation options

If certain requirements are met, the S8 and S81 ceiling mounts can be in-
stalled on existing substructures provided for the S23, EMD2, S5, S51, S6
or S61 ceiling mount.
A special mounting kit is available for installing the S8 and S81 ceiling
mounts on existing substructures (pre-installation sets of earlier ceiling
mounts). A major part of the special mounting kit is the adapter plate. In
this application, the adapter plate replaces the mount flange included in
the standard delivery package of the ceiling mount.
The disciplines concerned are ophthalmic surgery, ENT surgery and P&R
surgery.
Note:
Use this special mounting kit only if the pre-installation set for new instal-
lations (Cat. No. 1078-181) cannot be installed in the OR.
Only the pre-installation set for new installations ensures the typical
working distances (microscope axis - pivot axis 1) of 1,250 mm (49.2") for
the S8 ceiling mount or 1,000 mm (39.4") for the S81 ceiling mount, see
page 21 and page 23.

Working ranges

The EMD2 and S23 ceiling mounts have been designed for an optimum
working distance (center of mount flange to microscope axis) of 650 mm
(25.6"). With a stationary operating table, working ranges of 900 mm
(35.4") can be achieved if the adapter plate is rotated through 180°. If, in
addition, the adapter plate is mounted with an offset of 90 mm (3.5"), the
working range can be increased to 990 mm (39").
Note:
The recommended typical working ranges (= distance of pivot axis 1 to
microscope axis) for the S8 S81 ceiling mounts are:
e 1,250 mm ± 500 mm (49.2 ± 19.7") for the S8 ceiling mount.
e 1,000 mm ± 400 mm (39.4" ± 15.7") for the S81 ceiling mount.
This means that an S8 ceiling mount will be at its rear mechanical limit po-
sition in this type of installation, see illustration on page 102.

On-site preparations

Customer's responsibilities

Note:
Zeiss service staff can install the ceiling mount only if all points of the fol-
lowing checklist applicable to the relevant installation conditions have
been fulfilled.

Caution:
g Obtain the structural verification for an existing substructure from a
structural engineer, i.e. make sure that the engineer confirms the ef-
fective strength of the existing anchors.
Structural verification must be performed prior to the installation of the
mount.
Please add a copy of the "Confirmation of structural calculation" to
your order (see page 119).
g On-site conditions also include building vibrations, which the structural
engineer responsible must take into account right during the planning
phase (see page 26).
Obtain a written confirmation from your structural engineer stating that
possible building vibrations have been taken into account (see page
119).
g If an existing substructure is to be used, make sure that the maximum
inclination of the ceiling anchor plate under load does not exceed 0.2°.
g The structural engineer must check that no modifications have been
made to the substructure since the original installation.
g Obtain a written confirmation from a structural engineer stating that
the applicable national codes and regulations have been complied
with.
g If any differences exist between the planning documents and the ac-
tual on-site situation, please inform your contact at Carl Zeiss or the
planning expert prior to the installation of the ceiling flange or pre-in-
stallation set.
g Please note the information provided on page 104 for ordering an S81
ceiling mount for installation on an existing substructure (existing in-
termediate piece).

 Installation on an existing substructure 117

Warning!
g If an existing flange plate or intermediate piece must be exchanged,
never re-use the old anchors. New anchor holes must be drilled.
When calculating the effective strength of the new anchors, the struc-
tural engineer must take into account the weakening effect of the old
holes in the ceiling.

Planning the installation

g Inspect the mounting components supplied for completeness and
damage.
g Prior to the installation of a ceiling mount, you must always check that
the actual installation conditions - in particular the room height - corre-
spond to the specifications in the drawing.
g Two installers are required for mounting the mounting kit required for
installation on existing ceiling anchors.

 118 Installation on an existing substructure

Constructional requirements

The actual load on the ceiling depends on a large number of different fac-
tors. The requirements to be met by the ceiling or substructure result from
the addition of perpendicular forces and torques produced by the suspen-
sion system and accessories. These are the forces to be transmitted into
the structural ceiling via the ceiling anchors.
The column must be aligned in a vertical position (max. deviation ± 0.5°).

Forces and torques

Warning!
Your structural engineer must ensure in each individual case that the ex-
isting substructure and structural ceiling have a sufficient load capacity for
the forces and torques listed below. He must also take into account any
additional loads on the ceiling and add an appropriate safety margin, and
must observe the applicable national codes and regulations.
Caution:
e The perpendicular forces and torques specified below include an ad-
ditional load of 100 kg (220 lb), which is generated when a person
hangs on the end of the suspension arm (or the microscope). Further
safety margins have not been incorporated.
e The perpendicular forces and torques have been calculated on the ba-
sis of the maximum permissible load on the suspension arm.
