SAFETY INSTRUCTIONS
Please observe the safety instructions!
Improper operation of the system may
result in personal injury and cause
damage to objects!
1. Unplug the power cord in case of smoke,
smell or unusual noise.
2. Make sure no objects or parts of the body get
caught when operating the motor.
3. The piece of furniture must not be adjusted
in height if other people are located directly
in its vicinity.
4. Do not place any objects or parts of the
body between fixed or movable parts.
5. Height adjustment is only possible in jog
mode. If an obstacle is encountered or if
there is a functional fault, stop the
adjustment immediately.
6. Make sure adjacent objects are placed at
a minimum distance of 25 mm to prevent
them from being squeezed or sheared.
7. Ensure that the safety distances are 25
mm for movable parts (this also applies
for organisational elements which are
fitted above or underneath the furniture,
mounted to adjoining walls or building
parts such as open windows).
8. The protection against uncontrolled move
ment does not prevent objects being trap
ped! For physical reasons, „soft“
obstacles are not easily recognised and
evaluated, if at all.

5
SAFETY INSTRUCTIONS
9. In case of hitting an obstacle, slight
damage (scratching) to such obstacles
may result (table is lifted at nominal
speed).
10. Do not change or modify the control
mechanism or the operating device.
11. Never open the enclosure of the control
unit or power supply. Unauthorised ope
ning of the enclosure or improper repairs
may endanger the user and voids all
warranty claims.
12. Only professionals authorised by the
manufacturer may do maintenance or
repair any electrical equipment.
13. Do not operate devices in explosive
environments.
14. This table is admitted only for the
commercial office area and management.
15. This appliance must not be used by
any person (including children) with
limited physical, sensorial or mental
abilitiesor failing experience and/or
knowledge unless they are supervised by
a person responsible for their safety or
received instructions about how to use the
appliance.Children should be supervised
in order to make sure that theydo not play
with the appliance.
16. The manufacturer assumes no liability for
damage resulting from improper use.

6
SAFETY INSTRUCTIONS
17. Connection plug boards must be fixed
properly for easy plugging and unplugging.
Plugs and connection plug boards must
be located in such a way that no fluids
come into contact with electrical
equipment when the office furniture is
used properly.
18. The power cable must be secured in
the strain relief of the leg frame.
Interconnecting cables may be run loosely.
All lines and cables must be run in such a
manner as to avoid mechanical damage
(i.e., shearing, abrasion...).
19. Desks with flexible or height-adjustable
worktops require special care. Cables
must be sufficiently long to allow height
adjustments without damaging the cables
and wiring (i.e., stretching, crushing, ...).
20. If the power cord of this equipment is
damaged, it must be replaced by the
manufacturer, their customer service, or
a similarly qualified person so as to avoid
any risk.
21. Do not spill liquids into the control unit
or power supply unit, as this could cause
electrical shock or short circuits.
22. The operation of the control mechanism
and the power supply unit requires a
minimum of 5°C and a maximum
temperature of 40°C.

7
SAFETY INSTRUCTIONS
23. For the above reasons do not install the
control unit:
- above or in front of heat sources
(e.g. radiators)
- at places exposed to direct sunlight
- in small, unventilated or humid rooms
- near easily flammable materials
- near high-frequency devices
(e.g. transmitters, radiation equipment,
or similar devices)
Warning: In the event of a fault it is
possible that the table top moves a bit
during every attempt whilst operating
before the safety switch off kicks in.
Please take care to avoid the possible
danger of crushin.
Warning: During all reset procedures
(section 5) the collision protection is
not active. Please take care to avoid
possible danger of crushing.
Please note: Please note: If the product
is visibly damaged it must not be
installed or used further.
24. After 2 minutes of continuous operation
the system automatically shuts itself off
and cannot be used for an additional 18
minutes. This keeps the motor from
overheating.
25. Do not exceed maximum load of 75 kg.

Occupational health experts have issued standards and recommendations for preventing
harmful habits and their negative health impact at the office workplace. These standards
and recommendations are based on findings relating to an incorrect and tense sitting
posture which limits performance and produces long-term physical damage over time.
Sitting with a hunched back
doubles the burden (200%) on
the vertebral disks compared
to standing up (100%).

"PRO" MANUAL CONTROL
"LIGHT" MANUAL CONTROL
When the desk is used for the first time a reset must be done before you can operate the product. The reset causes all of the
columns to be brought to the same level. This ensures that the table top is positioned parallel with the ground. The controller
also saves the connected components in the standard configuration, such as columns or a sensor, if there is one attached. After
the reset, changes to the configuration are detected and considered to be errors. The system will not operate until the configura-
tion stored in its memory has been re-established.
Attention: Reset point is at table height 101 cm. The
safety shutdown is out of operation upon a reset! (See
page 7)

FEATURES. PEDESTAL-STOP – SHELF-STOP
These two features can be used to limit the table’s range
of movement (e.g. if a pedestal is located under the table).
A pedestal-stop position can be set in the lower half of the
range of movement, and a shelf-stop position can be set in
the upper half (this is also to be followed by deactivation). If
a pedestal-stop position is set, this is used as a new lower end
position; a shelf-stop position corresponds to a new upper end
position for the range of movement. To save a pedestal-stop or
shelf-stop position, do the following.
ACTIVATE POSITION
1. Position the table top where you want to set the new
pedestal-stop or shelf-stop position. Use the “lower table
position” or “raise table position” buttons to maneuver the
table into position.

FEATURES. PROTECTION
NOTES: The sensor’s sensitivity and the obtainable shut-off
threshold depend on the entire system; due to construction
characteristics, these features vary at different points.
Please note the safety instructions. (Side 4 - 7)
Increased protection against
uncontrolled movement: “Safety”
standard protection against
uncontrolled movement: “Base
Increased protection against uncontrolled
movement: Colour BLACK
Standard protection against uncontrolled
movement: Colour GREY
ATTENTION: The implementation must be the
same with both columns.
Standard protection against uncontrolled movement:
Every table is fitted with standard protection against uncon-
trolled movement (“Base”) which significantly reduces any
potential risk of getting caught or crushed. If the sensor
detects a spontaneous increase in force, as would happen in
a collision, the movement is stopped via a signal sent to the
controller, which then allows movement of approximately 40
mm in the opposite direction.
Warning: However, despite the protection against
uncontrolled movement there may still be a risk of get-
ting caught or crushed in exceptional cases, since the
interaction of mechanics and electronics is responsible
for the motor shutdown and not just the motor control-
ler. The mechanics, motor and environmental condi-
tions also affect the shutdown sensitivity. Kesseböhmer
ergonomic technology cannot therefore completely rule
out this residual risk and accepts no liability for it.
Reference values for spontaneous increase in force:
Standard protection against uncontrolled movement
at average 355N (Min 280N - Max 593N)
Increased protection against uncontrolled movement
at average 313N (Min 193N - Max 503N)
Increased protection against uncontrolled movement:
Additional collision sensors are integrated into the column in
the “Safety” version. These are detected automatically during
the reset operation upon first use (audible double-click). If the
sensor detects a spontaneous increase in force, as would hap-
pen in a collision, the movement is stopped via a signal sent
to the controller, which then allows movement of approximate-
ly 40 mm in the opposite direction.
Safety instructions: The protection against uncontrolled
movement, even with the sensor, does not necessarily
protect people from harm and therefore cannot berated
and/or labelled as a protective device.
