Preface
Dear User,
We are delighted that you have chosen a product from LINAK®.
LINAK systems are high-tech products based on many years of experience in the manufacture and development
of actuators, electric control boxes, controls and chargers.
This User Manual does not address the end-user. It is intended as a source of information for the manufacturer
of the equipment or system only, and it will tell you how to install, use and maintain your LINAK electronics. It
is the responsibility of the manufacturer of the end-use product to provide a User Manual where relevant safety
information from this manual is passed on to the end-user.
We are sure that your LINAK product will give you many years of problem-free operation.
Before our products leave the factory they undergo full function and quality testing. Should you nevertheless
experience problems with your systems, you are always welcome to contact your local dealer.
LINAK subsidiaries and some distributors situated all over the world have authorised service centres, which are
always ready to help you.
LINAK provides a warranty on all its products. This warranty, however, is subject to correct use in accordance
with the specifications, maintenance being done correctly and any repairs being carried out at a service centre,
which is authorised to repair LINAK products.
Changes in installation and use of LINAK systems can affect their operation and durability. The products are not
to be opened by unauthorised personnel.
The User Manual has been written based on of our present technical knowledge. We are constantly working on
updating the information and we therefore reserve the right to carry out technical modifications.

squeezing of fingers or arms.
Assure free space for movement of application in both directions to avoid
blockade.

Before installation, de-installation or troubleshooting
• Stop the DL7/DL7R
• Switch off the power supply and pull out the mains plug.
• Relieve the DL7/DL7R of any loads, which may be released during the work.
Before start-up:
• Make sure that the system has been installed as instructed in this User Manual.
• Make sure that the voltage at the control box is correct before the system is
connected to the mains.
• System connection. The individual parts must be connected before the control box
is connected to the mains. See the User Manual for LINAK actuators, if necessary.
During operation:
• If the control box makes unusual noises or smells switch off the mains voltage
immediately.
• Take care that the cables are not damaged.
• Unplug the mains cable on mobile equipment before it is moved.
• The products must only be used in an environment, that corresponds to their IP
protection.
Misc.
The actuator system has a sound level below 55dB(A) in typical applications.

Misc. on the DESKLINE®DL5/DL6 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 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®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 and control box. Exceeding the duty cycle will result in
a dramatic reduction of the life of the system.
The system range contains following products:
• 1 control box CBD4/CBD5/CBD6
• DL7/DL7R (1 - 4)
• 1 exchangeable mains cable
• motor cables (1 - 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 DL7
Mounting of the top frame
There are 2 ways to mount the motor housing to a top frame. Either use the 2 outer placed holes on the short side of the
motor housing and nut and bolt or use the 2 inner placed holes on the short side of the motor housing with thread (M8) and
screws. If you choose the screws, we advise you to fasten the desk frame by means of 4 pcs. of M8 screws of a good quality
and a suitable length, which must not go further into the motor housing than max. 30 mm.
We advise you to use the 6 pcs. of ø6 holes for mounting the tabletop.
Mounting of the foot
The DL7 is to be mounted on the foot by using 2 pcs. of
M8 screws of a good quality and a suitable length, which
must not go further into the column than max. 30 mm.
Always place the DL7 column on top of the foot construction due to the upside down design.
