Misc. on the DESKLINE®DL8/DL9/DL10/DL11 system
Warranty
There is a 36 months’ warranty on the DESKLINE products against manufacturing faults from the production
date of the individual products (see label).
LINAK A/S’ warranty is only valid in so far as the equipment has been used and maintained correctly and has not
been tampered with. Furthermore, the system must not be exposed to violent treatment. In the event of this,
the warranty will be ineffective/invalid. For further details, please see LINAK A/S ordinary conditions of sale.
Maintenance
Clean dust and dirt on the outside of the system at appropriate intervals and inspect them for damage and
breaks.
Inspect the connections, cables, and plugs and check for correct functioning as well as fixing points.
Service of double-insulated products:
Class II
A Class II or double insulated electrical appliance is one which has been designed in such a way that it does
not require a safety connection to electrical earth (US: ground).
The basic requirement is that no single failure can result in dangerous voltage becoming exposed so that it
might cause an electric shock and that this is achieved without relying on an earthed metal casing. This is
usually achieved at least in part by having two layers of insulating material surrounding live parts or by using
reinforced insulation.
There is no earthing/grounding means provided on the product, and no earthing/grounding means is to be
added to the product.
In Europe, a double insulated appliance must be labelled “Class II”, “double insulated” or bear the double
insulation symbol (a square inside another square).
Servicing a double-insulated product requires extreme care and knowledge of the system, and is to be done
only by qualified service personnel. Replacement parts for a double-insulated product must be identical to the
parts they replace.
The cleaners and disinfectants must not be highly alkaline or acidic (pH value 6-8).

Description of the DESKLINE®system
Each DESKLINE®actuator/column is equipped with a motor and parallel/memory drive is ensured by means of
software in the CBD4/CBD5/CBD6 that also takes account of an uneven load on the desk. Soft start and stop
are also part of this software, which ensures a soft start and stop when adjusting the desk.
Application of the DESKLINE®system:
Irrespective of the load the duty cycle 10% ~ 6 min./ hour or max. 2 min. at continuous use stated in
the data sheets, must NOT be exceeded as this will result in an overheating of the motor and control box.
Exceeding the duty cycle will result in a dramatic reduction of the life of the system.
The system range contains the following products:
• 1 control box CBD4/CBD5/CBD6
• DL8, DL9, DB9, DL10 or DL11 (1 - 3 (4))
• 1 exchangeable mains cable
• motor cables (1 - 3 (4))
• 1 DP1U/DPF1M (if memory function is required) DP1C/WDPL/DPT/DPF1C (if memory function and display
is required) or 1 DPA/DPB/DP1K/DP1V/DPFK/DPF1K (if only up/down is required.)

Mounting guidelines for the DL8/DL9/DL10/DL11 system
Mounting guidelines for DL8/DL9/DL10/DL11 (motor housing)
The motor housing is supplied with 6 M6 threaded holes meant for mounting onto the desk frame. We
advise you to fasten the desk frame by means of 6 pcs. M6 screws of a good quality (min. 8.8) and a suitable
length, which must not go further into the motor housing than max.10 mm. The thrust moment must not
exceed 7.5 Nm.
Max. 10 mm
Figure 1
Use all 6 M6 threaded
mounting holes for screws
Figure 2
DL9/DL11 motor housing:
be aware of the screw length.
It is recommended to use all six M6 threaded holes to mount the desk frame. The values of the
bending moments of the lifting units are only valid if the desk frame is mounted in this way. Tests
with fixing the motor housing only by means of the 4 threaded holes have proved that this is not
enough to obtain a sufficient torsional stability of the desk.
The column may not be twisted. If the column is twisting / rotated it may cause a failure. The
maximum moment that the column can adapt in the rotation direction is 200 Nm.

Mounting guidelines for the DL8 and DL9 (foot part)
The DL8/DL9 is supplied with 4 M6 threaded holes for the mounting of the foot.
We advise you to fasten the foot by means of 4 pcs. M6 screws of a good quality (min. 8.8) and of a suitable
length, which must not go further into the DL8/DL9 column than 20 mm.
The thrust moment must not exceed 10 Nm in the bottom plate thread. The 4 holes in the bottom of the
DL8/DL9 are placed on a Ø 42 mm diameter circle.
Foot
Mounting guidelines for the DL10 and DL11 (foot part)
The DL10/DL11 is supplied with 4 M6 threaded holes for the mounting of the foot.
We advise you to fasten the foot by means of 4 pcs. M6 screws of a good quality (min. 8.8) and of a suitable
length, which must not go further into the DL10/DL11 column than 20 mm.
The thrust moment must not exceed 10 Nm in the bottom plate thread. The 4 holes in the bottom of the
DL10/DL11 are placed on a Ø 46 mm diameter circle.
Foot
The holes in the foot must be
sufficiently larger than Ø 6 so
that it is possible to bring the
foot to a level line at assembly/
mounting.

Mounting guidelines for the DB9
The DB9 must not be activated when it is not mounted in guidance due to the risk of squeezing.
For detailled information on how to mount the DB9, please contact LINAK.

Mounting of the desk (misc.)
As the desktop amplifies the sound, we advise you to place a vibration/ shock absorbing material
between the desktop and the desk frame.
With a desktop thickness of 25 mm, it is necessary for the lowest edge of the lifting unit to be mounted max.
15 mm above floor level to obtain a desk height of only 600 mm in the lowest position. If e.g. 2 mm vibration
absorbing material is placed between the desktop and the desk frame the lifting unit must be mounted max.
13 mm above floor level.

LINAK recommends that the DESKLINE®DL8/DL9/DL10/DL11 system should only be used in push
applications with the motor housing uppermost.
Placement of a monitor directly above the motor may cause malfunction of the monitor. Magnets
inside the motor may interrupt the picture on the monitor depending on the distance and type of
monitor.
If this is the case the problem may be solved by placing an iron plate/tube or another magnetic
material, somewhat larger than the profile between the motor and the tabletop.
The mounting screws on the DP, DPA or DPB must be fastened with a max. torque of 1 Nm.
Figure 3
(Example of how to mount a 2 parallel DESKLINE® DL8/DL9/DL10/DL11 system)
Placement of a monitor directly above the motor housing may cause malfunction of the monitor. Magnets
inside the motor may interrupt the picture on the monitor depending on the distance and type of monitor.
If this is the case, the problem may be solved by placing an iron plate/tube or another magnetic material,
somewhat larger than the motor housing, between the motor and the desktop.

The CBD must not be packed in heat insulating material, but must be placed so that it can emit waste heat
into the surroundings. There are no ventilation holes to consider, the CBD emits heat through the surface.
The plug must be visible when the CBD is mounted so that the supply to the CBD can be disconnected at
replacement, if any.
The mounting screws on the control box must be fastened with a max. torque of 1 Nm.
The mounting surface to which the control box is attached should have a surface evenness of better than ±
0.5 mm.
CBD6 - bottom with cable grooves
The bottom of CBD6 is equipped with two cable grooves improving the cable management when mounting.
The grooves can be used to bypass the CBD for both motorcables and the mains cable (EU version only) from
one side to the other, giving a cleaner design.
Remember to lead the cables through the grooves before mounting the control box.
For mounting and operation of the desk panel, please see the separate user manual for desk panels.
Mounting guidelines CBD4/CBD5/CBD6
The control box is to be fastened with 4 screws (3 screws for CBD5 and CBD6) with a head diameter between
ø 8 and ø 10 mm. Out of regard for the tension surface ø 10 mm is preferable due to lower surface tension.
See drawing appendix for placing of mounting holes and the space the CBD takes up.

Electrical connection of the DL8/DL9/DB9/DL10/DL11 system
The systems is to be connected as shown on figure 7. Each DL8/DL9/DB9/DL10/DL11 is to be connected to
the sockets on the control box by means of the motor cables, which have a 6-pin plug in each end.
Finally the mains cable is to be mounted and power switched on. Please note that the control box
must only be connected to the voltage stated on the label.
CBD4/CBD5/CBD6 with earth
The CBD4/CBD5/CBD6 earth cable to be mounted on the desk construction (typically the top frame)in a way
that ensures good electrical contact. The function of the earth cable is to earth the desk and ground static
electricity. The earth connection does not protect other electrical products.
CBD4/CBD5 with mains cut-off (non ZERO models)
If the power cable is damaged it has to be replaced by an authorized LINAK service centre to avoid
any danger.

Initialisation of the DESKLINE DL8/DL9/DB9/DL10/DL11 parallel system
Press the down button and the legs/actuators run down to the “buffer” causing cut-off due to excess
current. Hereafter they run approx. 3 mm (from software version 1.66, previosely 5 mm) upwards and thereby
free of the “buffer”. When the movement stops, the system is initialised. During the entire initialisation
procedure, the down button must be pressed down.
If the button is released before the sequence is completed then the initialisation is interruppted and
must be started again from the beginning.
It is sometimes necessary to press the down button twice to start the initialisation. This is because the system
can be in different modes when the initialisation starts. There will be a 1.25 sec. delay. If an error situation
occurs at the end stop positions or the DL8/DL9/DB9/DL10/DL11 are changed to another stroke length, then
the CBD4/CBD5/CBD6 has to be initialised again.
The first two times the system runs into the outward end stop, it will automatically run approx. 3 mm back in
inward direction.
The CBD5 and CBD6 can control the DL8/DL9/DB9/DL10/DL11 in 2 parallel while the CBD4 can control in 2,
3, and 4 parallel so that the desk is always kept horizontal.

Page 18 of 32
Anti-Collision™
The function anti-collision is a new option for the standard CBD4/CBD5/CBD6 advanced control box. A
system with anti-collision can limit material damages to a desk if a collision with a solid object should occur.
Anti-collision is working for DL9. The other DL types require a configuration of the control box.
Enabling the anti-collision
To enable the anti-collision function a little plug called a dongle must be mounted in one of the 2 control
ports. The function is only active when the dongle is mounted. – If you remove the dongle again you disable
the function.
Method of operation
When the DL’s are running the CBD4/CBD5/CBD6 monitors the current consumption on each channel use
a special algorithm. If the current consumption on one channel is increased more than a predefined value
a collision is assumed and all channels are stopped immediately and all DL’s will start to run in the opposite
direction (approx. 50 mm). This return drive is done automatically and continues with or without any control
button pressed (for max. 2.5 sec.).
The anti-collision sensitivity is different in up and downward direction. Upwards the force is approx. 20 kg.
Downwards the load will be approx. 40 kg + the load on the DL (the desk + what is on top of the desk). The
40 kg are needed to activate the anti-collision function.
Situations where the anti-collision does not work
There are situations where the anti-collision will not be activated. These situations are:
• If the collision happens during the initialisation phase
• If the collision happens within the first 1000 m sec or after the control button has been released
• If the collision happens between the floor and the table and the load on the desk + the weight of the legs
is lower than 40 kg.
• If the collision time span is too long time, e.g. if the collision is with a soft object

Page 19 of 32
DL11 with PIEZO™: description of the feature
For optimised safety against squeezing and blocking on a desk, LINAK has developed a DL11 columns
with integrated sensor, called PIEZO. The new option minimises the risk for damages on a desk caused by
squeezing or blocking of obstacles in up and down direction. Examples could be driving down into an office
chair or into a container or up into a windowsill. To a certain extent, the system also increases the personal
safety, but it does not comply with legislation describing personal safety.
PIEZO allows the DL11 columns to have the standard built-in dimension and the standard stroke length. There
are no visible changes to the column.
Examples where PIEZO avoids squeezing situations.
Do not use the DL11 with PIEZO in combination with a crossbar or a foot construction where you
place the column in a tube welded on the foot.

Disposal of LINAK’s products
As LINAK’s customers often ask us how our products can be disposed of or scrapped we have prepared this
guidance that enables a classifi cation to different waste fractions for recycling or combustion.
Guidance
We recommend that our products be disassembled as much as possible and divided into different waste
groups for recycling or combustion.
For example, waste can be sorted into metals, plastics, cable scrap, combustible material, and recoverable
resources.
Some of these main groups can be further divided into subgroups; e.g. metal can be divided into steel/
aluminium/copper and plastic can be divided into ABS/PA/PE/PP.
As an example, the table below breaks down the different components in LINAK products to various recycling
groups:
