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.

Failing to follow these instructions can result in the product being damaged
or being destroyed.
Safe use of the system is possible only when the operating instructions are read
completely and the instructions contained are strictly observed.
Failure to comply with instructions marked with the ”NOTE” symbol may result in
serious damage to the system or one of its components.
It is important for everyone who is to connect, install, or use the systems to
have the necessary information and access to this User Manual. Follow the
instructions for mounting – risk of injury if these instructions are not followed.
The appliance is not intended for use by young children or infirm persons
without supervision.
If there is visible damage on the product it must not be installed.
Note that during construction of applications, in which the actuator is to
be fitted, there must be no possibility of personal injury, for example the
squeezing of fingers or arms.
Assure free space for movement of application in both directions to avoid
blockade.

Before installation, re-installation, or troubleshooting:
• Stop the DL1A
• Switch off the power supply and pull out the mains plug.
• Relieve the DL1A 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 of 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®DL1A 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
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®DL1A system
Each DESKLINE®DL1A 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.
The DESKLINE®DL1A system range contains the following products:
• 1 control box CBD4/CBD5/CBD6
• 1 single DL1A 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/DP1V/DPF1K (if only up/down is required.)
Options:
• Possibility of running extra actuators (LA31 with hall)
Application of the DESKLINE®DL1A 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.
Maximum load for each DL1A: 1600 N
Maximum load for a system with CBD4 400 W: 3200 N
Maximum load for a system with CBD4 600 W: 4800 N
Maximum load for a system with CBD5 500 W: 3200 N
Maximum load for a system with CBD6 375 W: 2400 N

Mounting guidelines for the DESKLINE DL1A
Figure 2
Figure 1
The lifting units are normally mounted with the motor housings upwards and pointing towards each other
(see figure 2).
The aluminium motor housing is supplied with 6 pcs. of M6 threaded holes meant for mounting on the desk frame.
The threaded holes are rolled into the aluminium housing.
It is recommended to use all 6 M6 threaded holes. As the tabletop amplifies the sound we advise you to place a
vibration/shockabsorbing material 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 countersinked 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.
Max. 15 mm
