Misc. on the DESKLINE®DB5/DB6 system
This system is a DESKLINE system developed for desks and for indoor use in offices. 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
This DESKLINE product is subject to warranty pursuant to the terms of LINAK DESKLINE Warranty Paper, available on the LINAK
website www.linak.com/warranty.
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®DB5/DB6 system
Each DESKLINE®DB5/DB6 actuator 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 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®DB5/DB6 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 system must not be allowed to collide with and be blocked by an external object. In such a case the working parts of DB5/
DB6 can be damaged. If the system collides with an object e.g. If the desktop is stopped by a window ledge, then the system
should be examined to see as to whether the DB5/DB6 still functions correctly.
The DESKLINE®DB5/DB6 system range contains following products:
• 1 control box CBD4/CBD5/CBD6
• 1 single DB5/DB6 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) or 1 DPA/DPB/DP1K/DP1V/DPF1K (if only up/down is required.)

Mounting guidelines for the DESKLINE®DB5 system
Figure 1
(Example of how to mount the DB5)
2 pcs. self
cutting plastic
screw Type K50
It is important that the correct screws are used.
Check that the screws are fitted correctly to ensure a correct function to prevent the guidance from coming apart
when the desktop is lifted.
Max. 10 mm
DB5/DB6
motor housing
The motor housing is supplied with 6 pcs. M6 threaded holes meant for mounting on the desk frame. We advise you to fasten
the desk frame by means of 6 pcs. 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 7.5 Nm.

Page 11 of 28
Figure 2
(Example of how to mount the DB5 system)
LINAK recommends that the DESKLINE®DB5 system should be used in push applications - with the motor housing
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.

Inward direction: built-in dimension - tolerances – 5 mm
Outward direction: built-in dimension + stroke length + tolerances + 5 mm
The endstop system in the DB5 is based on a buffer system meaning that you must be aware of the lengths when
initialising. The products must be able to drive:
DB5 (fully extended)
DB5 (fully retracted)

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 DB5/DB6 system:
The DESKLINE®DB5/DB6 system is to be connected as shown on figure 5. Each DB5/DB6 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.All DB5/DB6 actuators are connected on
the same side on the control box.
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.
Voltage must not be connected to CBD4/CBD5 until all actuators/legs have been connected. This must be observed to
ensure that CBD4/CBD5 can detect, which actuators/legs have been connected.
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 replaced by an authorized LINAK service centre to avoid any danger.

Initialisation of the DESKLINE DB5/DB6 parallel systems
The DESKLINE system is intialised by pressing the down key once or twice and holding it down until DB5/DB6 runs into end
stop, it will then automatically run approx. 3 mm out again. Only release the down key when the movement has completely
stopped.
If the key is released before the sequence is complete then the initialisation is interuppted and must be started again
from the beginning.
It is sometimes necessary to press the down key twice to start the initialisation, this is because the system can be in different
modes when the initialisation starts.
Approx. 3 mm
The CBD5 and CBD6 can control the DB5 and the DB6 in 2 parallel while the CBD4 can control the DB5 and the DB6 in
2, 3 and 4 parallel so that the desk is always kept horizontals.

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:
