Misc. on the DESKLINE®DL5/DL6 system
This system is a DESKLINE system developed for desks and for indoor use in of-
fices. Do not use it in industrial kitchens or in other enviroments that have to
be cleaned with aggressive detergents.
Do not bolt the legs to the floor so that free movement is prevented. This could
cause serious damage to the legs in fault situations.
Warranty
There is a 36 months’ warranty on the DESKLINE products against manufactur-
ing 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.
The cleaners and disinfectants must not be highly alkaline or acidic
(pH value 6-8).
Description of the DESKLINE®DL5/DL6 system
Each DESKLINE®DL5/DL6 lifting units is equipped with a motor and parallel/
memory drive is ensured by means of software in the CBD4/CBD5 that also
takes account of oblique 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®DL5/DL6 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 a superheating of the motor, the brake and the spindle nut. Exceeding
the duty cycle will result in a dramatic reduction of the life of the system.
The DESKLINE®DL5/DL6 system range contains the following products:
• 1 control box CBD4/CBD5
• 1 single DL5/DL6 or 2, 3, or 4 parallel
• 1 exchangeable mains cable
• 1, 2, 3, or 4 motor cables
• 1 DP1U/DPF1M (if memory function is required) DP1C/WDPL/DPT/DPF1C (if
memory function and display is required) or 1 DPA/DPB/DP1K/DP1L/DP1V/
DPFK (Desk Panel without memory)

motor housing
The lifting units must always be mounted with the motor housings
upwards and pointing towards each other (see figure 2). The steel
motor housing is supplied with 6 pcs. of M6 threaded holes meant for
mounting on the desk frame.
It is recommended to use all 6 M6 threaded holes. As the tabletop ampli-
fies the sound we advise you to place a vibration/shock-absorbing mate-
rial between the tabletop and the table frame.
A suitable desk height in the lowest position can be obtained by mounting
the lifting unit on a 6-8 mm bottom plate by means of 4 pcs. of M6 counter-
sinked screws. We recommend you to use screws of min. quality 8.8. The thrust
moment must not exceed 10 Nm in the bottom plate thread.
The motor housing is supplied with 6 pcs. of M6 threaded holes meant for
mounting on the desk frame. We advise you to fasten the desk frame by means
of 6 pcs. of M6 screws of a good quality and a suitable length, which must not
go further into the motor housing than max.10 mm. The thrust moment must
not exceed max. 7.5 Nm.

Mounting bracket
To avoid damage of the lifting unit there must be min. 1 mm space
between the end of the screw for the mounting bracket and the surface
of the lifting unit (see figure 1). The use of any longer screws will come
into contact with the inner parts. This will result in an irregular operation
or even damage the lifting unit.
The DESKLINE®DL5/DL6 system can only be used in push applications
with the motor housing mounted upwards.
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 tabletop.
The end-stop system in the DB6 is based on a buffer system meaning that
you must be aware of the lengths when initialising. The products must
be able to drive:
Inwards direction: built-in dimension - tolerances – 5 mm
Outwards direction: built-in dimension + stroke length + tolerances + 5 mm

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 sur-
face evenness of better than ± 0.5 mm.
For mounting and operation of the desk panel, please see the separate user
manual for desk panels.
CBD4 - Control box
Mounting guidelines CBD4/CBD5
The control box is to be fastened with 4 screws (3 screws for CBD5) with a head
diameter between ø 8 and ø 10 mm. Out of regard for the tension surface ø
10 mm is preferable. See drawing appendix for placing of mounting holes and
the space the CBD takes up.

Electrical connection of the DL5/DL6 system:
The DESKLINE®DL5/DL6 system is to be connected as shown on figure 4. Each
DL5/DL6 is to be connected to the sockets on the control box by means of the
motor cables, which have an 6-pin plug in each end.
Please note that the control box must only be connected to the voltage
stated on the label.
Voltage must not be connected to the CBD4/CBD5 until all actuators/legs
have been connected. This must be observed to ensure that the CBD4/
CBD5 can detect, which actuators/legs have been connected.
Finally, the mains cable is to be mounted and power switched on.

Initialisation of the DESKLINE DL5/DL6 parallel systems
The DESKLINE system is intialised by pressing the down button once or twice and
holding it down until DL5/DL6 runs into end stop, it will then automatically run
approx. 3 mm out again and hereafter slowly running in again. Only release the
down button when the movement has completely stopped.
If the key is released before the sequence is completed then the initiali-
sation is interupted and must be started again from the beginning.
It is sometimes necessary to press the down button twice to start the initiali-
sation this is because the system can be in different modes when the initiali-
sation starts.

The CBD5 can control DL5 and DL6 in 2 parallel and 3 parallel while the CBD4
can control DL5 and DL6 in 2, 3, and 4 parallel so that the desk is always kept
horizontal.

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 dif-
ferent 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, combus-
tible 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:
