Installation position in the OR

The optimum installation position of the ceiling anchor plate is dependenton the required position of the operating table in the OR. The followingoverview shows the ceiling mounts in their optimum operating positions.

We recommend installing the ceiling anchor plate above the area of thepatients' feet.

Alternatively, the ceiling anchor plate can be installed laterally to the op-erating table. Please see the illustration for the recommended distancesof the ceiling anchor plate from the surgical field.

In unfavorable on-site conditions, it may not be possible to implement theinstallation in the recommended positions. Installation options forcramped conditions are shown from page 16 onwards. OR illuminatorscan only be used with restrictions or not at all in this case.

On-site preparations

Customer's responsibilities

Note:The Zeiss service department can only install the ceiling mount if all pre-conditions listed in the specification below and applicable in the individualmounting situation on site have been met.

The actual load on the ceiling depends on a large number of different fac-tors which a structural engineer must specify accurately for the individualcase. See “On-site preparations” on page 30.

Important:• It is mandatory that you have the mounting situation checked by a

structural engineer during the planning stage. Structural evidence must be submitted before the stand is mounted.We recommend that you keep the structural evidence with the docu-ments on the ceiling mount.

• Have a structural engineer confirm in writing that the applicable na-tional regulations have been met.

• Enclose a copy of the structural evidence with your order. See “Con-firmation of the structural calculation and execution of installation” onpage 49.

• Should the actual mounting situation differ from the planning docu-ments, consult your contact at Carl Zeiss or the planning engineer be-fore mounting the pre-installation set.

• As installation site, choose a layer that is as flat and as hard as possi-ble, for example a concrete surface. Never embed the pre-installationset into the ceiling but always install it directly on the surface.

• The conditions on site also comprise building vibrations that must betaken into account by your structural engineer already at planningstage, see page 26. Have your structural engineer confirm in writing that he/she has takenpossible building vibrations into account, see page 49.

• Have a structural engineer confirm in writing that he or she has com-plied with the ceiling stiffness values, see page 28.



Caution!• If an existing ceiling anchor plate or intermediate piece is to be re-

placed, the old dowel anchors must not be re-used. Instead, you mustdrill new holes. When the structural engineer calculates the effective strength of thenew anchors, the reduction of the ceiling strength caused by the olddrill holes must be taken into account.

Planning the installation

• On receipt of delivery, check the assembly components for complete-ness and potential damage.

• Before installing the ceiling mount, always check whether the dataspecified in the dimension sheet comply with the actual installation sit-uation, particularly in respect of room height.

• Ensure that the dowel anchors calculated by your structural engineerare mounted properly, and that the appropriate nuts and washers formounting the ceiling anchor plate are available at the installation sitetogether with information on the maximum tightening torque.

• For a new installation, the pre-installation set must be mounted beforethe false ceiling is mounted.

• A minimum of 2 installers is required for mounting the pre-installationset.

• For installing a ceiling mount in rooms with supply-air ceilings, the sup-ply-air ceiling must be properly prepared, see page 32.



Notes on building vibrations

The on-site requirements also include the low-vibration design of theceiling 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 canalso 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 strongimpact against ceiling, wall or floor. This is the most frequent, but leastcritical type of excitation. The ZEISS ceiling mount features excellentdamping 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 viathe building. This type of excitation is extremely rare, but may lead to per-manent vibration of the ceiling mount in extreme cases. This becomesparticularly visible at high magnifications as used in the surgical micro-scope. The following result of a study is intended to help you understand constantvibration excitation occurring in rare cases in ceiling mounts, eliminate itor 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 particularagainst higher frequencies above 10 Hz which are typical of buildings withelectrical excitation factors. Nevertheless it may happen in rare cases,when the arms of the ceiling mount are in a specific position, that higherfrequencies which are critical for this particular constellation lead to vibra-tions (e.g.: 17 Hz, ..., 19 Hz, ...).

Such excitation factors can usually be suppressed by the following meas-ures:

– elimination of the excitation source (e.g. repair or damping of the airconditioning system)

– 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 is unable to give anabsolute guarantee for the vibration-free suspension of the ceiling mount,even if the building meets the applicable ISO standards. This also applies to replacement installations for existing, earlier Zeissceiling mounts. However, if building vibrations did not cause any problemsin the old system, problems are generally unlikely to occur in the replace-ment system.It is highly improbable that constant vibrations are transferred to theceiling mount if all requirements regarding vibrations in the OR ceiling aremet.

– Max. vibration velocity (RMS) at the installation points for the ceilingmount.

– Vmax < 0.1 mm / s or Vmax < 4 milli-inches / s or below the curves (di-agram) for the specified frequency range.

Ceiling stiffness

A sufficient stiffness, or rigidity, of the ceiling is an on-site requirement.This must be taken into consideration during the planning phase of theceiling mount.

The stiffness/rigidity of a concrete ceiling has been calculated as an ex-ample. The stiffness/rigidity should be greater than the specified refer-ence value so that the system is attached with low vibration.

E*J*100/L3 > 150 kN/cm

Customer's preparatory responsibilities, overview

– Mounting the pre-installation set

– Install and connect the cable for the electrical supply of the unit at thepre-installation set.

– The supply line of the ceiling mount must be fused with a 1-pole auto-matic circuit breaker 230V: 10A (115V: 20A) or with a 1-pole fuse230V: 10A, slow-blowing (115V: 20A, slow-blowing). The fuse mustbe installed in phase.

– Downstream, install a 2-pole line switch with a permissible minimumcontact load of 230V: 10A (115V: 20A). As an alternative, a lineswitch may be installed at the unit in the frame of the optional instru-ment socket. Also refer to page 50 and page 54.

– Install the wall socket (flush- or surface-mounted).

– Install the ductwork and cables for:

– Power cable, 3 x 1.5mm2 (3 x AWG16)

– Wall socket for foot control panel (optional)

– Potential equalization (optional)

– Video, inner diameter 50mm (2"), optional

– OR illuminators (24V DC with emergency power supply, built onsite) (optional)

– Other OPMI accessories, e.g. BIOM/SDI, additional illumination,AUX output, etc. (optional)

– We recommend that you install additional ductwork for future ex-pansion, e.g. leading to the central OR control panel.

– The maximum permissible cable length for the Speed Focus is10m (394"). If this is insufficient, a signal amplifier must be in-stalled.




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 fromthe addition of perpendicular forces and torques produced by the suspen-sion system and accessories. These are the forces to be transmitted intothe structural ceiling via the ceiling anchors. The column must be aligned in a vertical position (max. deviation ± 0.5°).

Forces and torques

Caution!Your structural engineer must ensure for the individual case on site thatthe structural ceiling can receive the forces and torques defined below.The structural engineer must take into account any other loads on theceiling, if applicable, and add the required safety margin under observa-tion of the applicable national regulations.

Important:– An additional load of 800N (180lbf) has been included in the perpen-

dicular forces and torques specified below. It is generated by having aperson hang on to the end of the spring arm (i.e. the microscope). Oth-er safety margins are not taken into account.

– The perpendicular forces and torques were dimensioned based on themaximum permissible payload at the spring arm.

For a ceiling mount S8 or S81 on its own (without accessories at the ac-cessory interface), the structural ceiling must be able to take the followingloads:

Ceiling mount S8

– Perpendicular force: no less than 3115N (700lbf)

– Torque: no less than 3245Nm (2393lbf.ft)

Ceiling mount S81

– Perpendicular force: no less than 2717N (611lbf)

– Torque: no less than 2316Nm (1708lbf.ft)





Pre-installation set for mounting to ceiling structures with supply-air ceiling

Important:When mounting support arm systems in supply-air ceilings, the type ofceiling mounting must be individually adjusted to the structural character-istics of the make of the respective supply-air ceiling.

To bridge the distance between the structural ceiling and the non-struc-tural false ceiling, install a false ceiling set. The length of the appropriatethreaded rods and spacer tubes will be adapted on site. The necessary planning activities should be carried out in coordinationwith the manufacturers of the supply-air ceiling and with Carl Zeiss.

Please specify in your order dimension (A), the distance between thebottom edge of the structural ceiling and the bottom edge of the falseceiling.

Note:– Dimension (A) is the height of the false ceiling. It must not exceed 800

mm. Otherwise, a ceiling substructure must be mounted for bridgingthe oversize. Dimension (Z) is the height of the supply-air ceiling.

– It is imperative that the false ceiling set (2, 3) and the cables for theelectrical connections are mounted before installing the supply-airceiling. Subsequent installation will be impossible for lack of space.

– An inspection chamber (5) free of compressed air must be providedfor the installation work. The inner dimension of the chamber (S) mustbe greater than the ceiling opening (M).

– A seal (7) provided by the manufacturer of the supply-air ceiling canbe installed to seal the inspection chamber off from the OR theater.

Planning the electrical installation

The power lines on the site of installation must be run up to the interfaceplate. In addition, the potential equalization lines must be run to the termi-nals on the interface plate.

Warning!– 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.

– The electrical installations of the room concerned must comply withthe requirements of the applicable national regulations. In the FederalRepublic of Germany, VDE 0107 applies.

– The number of circuits is dependent on the customer's specific carriersystem configuration.

– If several circuits are required by the customer, appropriate allowancemust be made on the interface plate.

– Multiwire lines must be provided with wire end sleeves.



Installing the conduits

The cables may be installed above the false ceiling or in ductwork in thestructural ceiling. When installing cables in the ductwork in the structuralceiling, there are two mounting options:

– The ductwork emerges next to the ceiling anchor plate (8).

– The ductwork emerges in the center of the ceiling anchor plate (9).

The ductwork has an inner diameter of 22 - 50mm (0.9 - 2").

The MediLive video line requires ductwork of an inner diameter of min.35mm (1.4").

300 mm (11.8") ceiling panel extension

If the distance between the structural ceiling and the false ceiling (T) issignificantly smaller than 200 mm (7.9"), i.e. smaller than 190 mm (7.5"),you will need the ceiling panel extension (1). Then, the ceiling panel (2)on its own will not be sufficient to fully cover the pre-installation set (3).The ceiling plate extension (1) cannot enclose the interface plate (5). If theinterface plate (5) also projects from the false ceiling, you need to orderthe "Cover for pre-installation set" (Cat.-No. 1139-023).

A ceiling panel extension 300mm (11.8") (1177-632) plus mounting in-structions can be ordered from the Zeiss service department as a sparepart.On site, the installer will cut the 300mm ceiling panel extension to matchthe individual requirements, and mount it in accordance with the mountinginstructions (1177-632).

Accessory interface

Next to the flange area for the carrier arm of the ceiling mount, the mountflange also features a flange area for an accessory carrier. This is the ac-cessory interface designed as a hole circle, see page 68.

This accessory interface permits you to mount an accessory carrier e.g.for OR illuminators, supports, monitor brackets, trays for video systems orsimilar devices.

Coupling of the Zeiss system with accessories from other manufacturers

Important:Combining a device by Carl Zeiss with accessories (OR illuminators,monitor holders, etc.) by other manufacturers results in a new medicalsystem. The producer of the new system must procure the required pre-conditions for that system (approval, qualification, structural analysis etc.) In this context, please comply with the operating instructions by the man-ufacturers of the accessory assemblies. For more information, contact ourservice department or authorized dealerships.

• Check the feasibility of the installation in detail together with the man-ufacturer of the relevant accessory module (OR illuminator or monitorbracket).



Installation position

Important:When defining the positions and motion ranges of the accessory compo-nents, please take the geometry of the ceiling mount into account in re-spect of the risk of collision. For the dimensions, please see:

– the figure on page 7 for ceiling mount S8;

– the figure on page 8 for ceiling mount S81.

Note:By default, the mount flange is mounted 45mm (1.8") below the falseceiling. For the dimensions of the pre-installation set, please refer to thefigure onpage 70.



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 flangearea 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 ceilingmount and is included in its delivery package.

Ceiling panel (2) is used to cover the mount flange and the entire openingin the false ceiling. The opening in the false ceiling must not be larger than600 mm x 600 mm (23.6" x 23.6"). Two openings are provided in theceiling panel, one for the ceiling mount and one for an accessory carrier.

Cover frame (3) closes the remaining space between the square tube ofthe ceiling mount and the ceiling panel. Blind cover (4) is supplied together with the ceiling panel, permitting theopening for the accessory carrier to be completely closed. You can makean opening in blind cover (4) which fits the accessory carrier used.A dummy cover is available for closing the opening in the false ceiling untilthe ceiling mount is installed. Also see page 50 and page 54.

Note:The S8 or S81 ceiling mount is delivered with the following componentsalready mounted: mount flange (1), cover frame (2) and carrier arm of theceiling mount (5), as in the configuration example on page 69.

Note:Zeiss service department can only install the ceiling mount if all precondi-tions listed in the specification below and applicable in the individualmounting situation on site have been met.

The actual load on the ceiling depends on a large number of different fac-tors which must be specified accurately for the individual case by a struc-tural engineer. Refer to page 30, "On-site preparations for ceilingmounts".

Important:• The additional perpendicular force and the additional torque attributa-

ble to the accessory components mounted to the accessory interfacemust be taken into account separately by your structural engineer, i.e.he/she must add these to the perpendicular force and torque appliedto the ceiling by the ceiling mount proper.

• It is mandatory that you have the mounting situation checked by astructural engineer during the planning stage. Structural evidence must be submitted before the stand is mounted.We recommend that you keep the structural evidence with the docu-ments on the ceiling mount.

• Have a structural engineer confirm in writing that the applicable na-tional regulations have been met.

• Enclose a copy of the structural evidence in the form of a "Structuralanalysis certificate" (see page 75) with your order.

• Should the actual mounting situation differ from the planning docu-ments, consult your contact at Carl Zeiss or the planning engineer be-fore mounting the pre-installation set.

• The conditions on site also comprise building vibrations that must betaken into account by your structural engineer already at planningstage, see page 26. Have your structural engineer confirm in writing that he/she has takenpossible building vibrations into account, see page 75.

• Have a structural engineer confirm in writing that he or she has com-plied with the ceiling stiffness values, see page 28.



Forces and torques

Caution!Your structural engineer must ensure for the individual case on site thatthe structural ceiling can receive the forces and torques defined below.The structural engineer must take into account any other loads on theceiling, if applicable, and add the required safety margin under observa-tion of the applicable national regulations.

Note:For the accessory interface, the maximum permissible perpendicularforce and the maximum permissible torque follow from the difference be-tween the maximum permissible values for the pre-installation set and thevalues for the ceiling mount; i.e. "pre-installation set minus ceiling mountequals accessory interface".

Pre-installation setAs a maximum, the pre-installation set can receive the following perpen-dicular force and torque:

Ceiling mount S8 or S81For a ceiling mount S8 or S81, the pre-installation set must receive the fol-lowing perpendicular force and torque:The values below comprise an additional load of 800N (180lbf) added asa safety margin.

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 preparations for connection of accessory components

• In the building, the power cables must be installed up to the interfaceplate.

• If required, lay control cables and/or monitor connections up to the in-terface plate.

• In case of flush mounting, provide a sufficient number of ducts of suf-ficient cross-section.

• Additionally, lay cables for the potential equalization to the terminalson the interface plate.

Discipline-specific installation positions

Installation positions for ophthalmology and ENT 79

Installation position for P&R, Hand 92

Installation position for Neuro, Spine, Uro and Gyn 95


78 Discipline-specific installation positions

The various surgical disciplines and the respective spatial situations re-quire different installation positions of the ceiling mounts S8 and S81.

This chapter specifies some recommended installation positions of ceilingmounts S8 and S81 for the different surgical disciplines.

Note:In case of unfavorable spatial situations, it may be necessary to deviatefrom the recommended installation positions. As a result, use of OR illu-minators may be impossible in full or in part for lack of space.

Important:The recommended installation positions for the various surgical disci-plines do not replace careful planning on your part. Careful planning is theonly way to ensure smooth, collision-free working processes during sur-gery.

Scale 1:20

All recommended installation positions for the various surgical disciplinesare shown in a scale of 1:20. Usually, they can be taken over directly intothe construction plan.

Transparent sheet

To simplify your planning efforts, you can copy the installation position forthe applicable surgical discipline shown in scale 1:20 on a transparentsheet. Then, put the transparent sheet on the construction plan and moveand turn it to the appropriate position.

Note:In the following drawings, the position of the ceiling mount shown in lightgray, shaded representation of the ceiling mount is the alternative, mirror-inverted mounting option.



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 ophthalmologyThe S8 or S81 ceiling mount is positioned above the patient's foot area(centered relative to the operating table).

Alternative installation position for ophthalmologyThe S8 or S81 ceiling mount is positioned laterally to the patient (centeredrelative to the patient's head).

Recommendation for ENT

GeneralTwo OR illuminators are normally used for ENT. Do not mount these ORilluminators (ceiling lights) on the mount flange of the ceiling mount, buton separate ceiling flanges. Otherwise, collisions are liable to occur if bothceiling lights are pointed at the surgical field at an angle from behind thesurgeon.

Preferred installation position for ENTThe 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 ENTThe S8 or S81 ceiling mount is installed in a centered position behind thepatient's head.Again, the OR illuminators are not mounted on the flange of the ceilingmount, but on separate ceiling flanges.

100 Installation on an existing substructure



Installation options

Under certain circumstances, the ceiling mounts S8 and S81 can be con-nected to existing substructures of ceiling mounts S23, EM2, S5, S51, S6,or S61.

Note:It is not possible to install the ceiling mount on an existing ceiling track.

A special installation set is available for adapting ceiling mounts S8 andS81 to existing substructures (pre-installation sets of older ceilingmounts). The key element of the special mounting set is the adapter plate.In this application, the adapter plate replaces the mount flange comprisedin the delivery by default.

This concerns opthalmologic surgery, ENT surgery, and P&R surgery.

Note:Only use this special installation set if you are unable to install the pre-in-stallation set for new installations (Cat.-No. 1078-181) in the OR.The typical working distances (microscope axis - pivot axis 1) of 1250mm(49.2") for ceiling mount S8 or 1000mm (39.4") for ceiling mount S81 canonly be implemented with the pre-installation set for new installations;also refer to page 21 or page 23.

Working ranges

Ceiling mounts EMD2 and S23 are dimensioned for optimum working dis-tances (mount flange to microscope axis) of 650mm (25.6"). With a fixedOR table, working distances of 900mm (35.4") can be achieved with theadapter plate rotated by 180°. With an additionally possible lateral shiftingof the adapter plate by 90mm (3.5"), working distances of 990mm (39")can be achieved.

Note:For ceiling mounts S8/S81, the typical recommended working ranges (= distance between pivot axis 1 and microscope axis) are as follows:

– 1250mm ± 500mm (49.2" ± 19,7") for ceiling mount S8.

– 1000mm ± 400mm (39.4" ± 15,7") for ceiling mount S81.

Accordingly, you have reached the rear mechanical stop when adaptingceiling mount S8, as shown in the drawings on page 104.



Mounting options

Using the adapter plate, the S8 or S81 ceiling mount can be mountedon:

– existing intermediate piece (305658-0000.000) of an S23 or EMD2ceiling mount, with the adapter plate in a laterally offset position andthe electrical components mounted on the mounting bracket.

– existing intermediate piece (305658-0000.000) of an S23 or EMD2ceiling mount, with the adapter plate in a centered position and option-ally:

– electrical components mounted on the mounting bracket or

– electrical components mounted on the adapter plate.

– existing ZDK intermediate piece (305658-0000.000) of an S5, S51, S6or S61 ceiling mount, and optionally:

– electrical components mounted on the mounting bracket or

– electrical components mounted on the adapter plate.

The different mounting options are described in more detail in the fol-lowing.

Adapter plate (1071-924)

1 Hole circleThe Ø440mm (17.3") hole circle is intended for installation to the ex-isting intermediate piece ZDK (305942-9103.000) of ceiling mountsS5, S51, S6, or S61.

2 Lines of boresThe lines of bores are intended for installation to the existing interme-diate piece (305658-0000.000) of ceiling mounts S23 or EMD2.Alternatively, the adapter plate may be laterally displaced by90mm (3.5") before mounting it to the intermediate piece of ceilingmounts S23 or EMD2.

Mounted adapter plate, laterally displaced by 90mm (3.5")

The two following drawings show a mounted adapter plate laterally dis-placed by 90mm (3.5"). The respective working area for the OR micro-scope is between the sectors marked with dotted lines. For reason of theabove, check when adapting a ceiling mount S8 or S81 whether it is pos-sible to reach the optimum working distance by moving the OR table:1250mm (49.2") for the S8 and 1000mm (39.4") for the S81.

Caution:When ordering an S81 ceiling mount for installation on an existing inter-mediate piece, you must determine and specify dimension B in the "Ordersheet for S81 ceiling mounts in ORs with false ceilings“ (see page 57) asfollows:

• Measure the distance between the bottom surface of the intermediatepiece to the floor.

• Subtract the probable distance between the adapter plate and the in-termediate piece and enter the value obtained as dimension B in theorder sheet.

The assumed distance between the adapter plate and the intermediatepiece is at least 50mm (1.97") when the electrical components are posi-tioned laterally on the mounting bracket.

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

Caution:• 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 themount.Please add a copy of the "Confirmation of structural calculation" toyour order (see page 120).

• On-site conditions also include building vibrations, which the structuralengineer responsible must take into account right during the planningphase (see page 26). Obtain a written confirmation from your structural engineer stating thatpossible building vibrations have been taken into account (see page120).

• If an existing substructure is to be used, make sure that the maximuminclination of the ceiling anchor plate under load does not exceed 0.2°.

• The structural engineer must check that no modifications have beenmade to the substructure since the original installation.

• Obtain a written confirmation from a structural engineer stating thatthe applicable national codes and regulations have been compliedwith.

• If any differences exist between the planning documents and the ac-tual on-site situation, please inform your contact at Carl Zeiss or theplanning expert prior to the installation of the ceiling flange or pre-in-stallation set.

• Please note the information provided on page 106 for ordering an S81ceiling mount for installation on an existing substructure (existing in-termediate piece).



Warning!• 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 oldholes in the ceiling.

Planning the installation

• Inspect the mounting components supplied for completeness anddamage.

• Prior to the installation of a ceiling mount, you must always check thatthe actual installation conditions - in particular the room height - corre-spond to the specifications in the drawing.

• Two installers are required for mounting the mounting kit required forinstallation on existing ceiling anchors.



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 fromthe addition of perpendicular forces and torques produced by the suspen-sion system and accessories. These are the forces to be transmitted intothe structural ceiling via the ceiling anchors. The column must be aligned in a vertical position (max. deviation ± 0.5°).

Forces and torques

Caution!Your structural engineer must ensure for the individual case on site thatthe existing substructure and the structural ceiling can receive the forcesand torques defined below. The structural engineer must take into ac-count any other loads on the ceiling, if applicable, and add the requiredsafety margin under observation of the applicable national regulations.

Important:– An additional load of 800N (180) has been included in the perpendic-

ular forces and torques specified below. It is generated by having aperson hang on to the end of the spring arm (i.e. the microscope). Oth-er safety margins are not taken into account.

– The perpendicular forces and torques were dimensioned based on themaximum permissible payload at the spring arm.

For a ceiling mount S8 or S81 on its own (without accessories at the ac-cessory interface), the structural ceiling must be able to take the followingloads:

Ceiling mount S8 Ceiling mount S81

– Perpendicular force: min. 3115N min. (700lbf)

min. 2717N (min. 611lbf)

– Torque: min. 3245N (min. 2393lbf.ft)

min. 2316N (min. 1708lbf.ft)
