4.2 Fitting the skids
If the side frame has skids welded to it, please continue with point 4.2.
If the side frame has screwed-on skids, they must first be fitted to the mounting legs. To do so, use the screws
as given in the table-top support frame drawing.
The max. tightening torque is 10 Nm!
The max. screw-in depth of the screws M10 into the drive column is 12 mm.
With asymmetric skids (C-form), keep in mind that one left and one right side frame might be required.
4.3 Assembly of the desktop
Now fasten the desktop to the desk base in accordance with the base drawing. To accomplish that, ø7.0 mm
holes are provided on the desk frame; they are suitable for ø5.5 to ø6.5 mm bolts. Use all provided bolting

4.4 Assembly of the controller and hand-switch
First fit the two controller brackets into the keyholes in the longitudinal spar. Then turn them clockwise through
90 degrees.
Note: Ensure that the grooves for the cable guidance are on one side, so that the cables can be
later laid skirting by the STAND.CONTROL C1.
Now position the locking catches of the brackets on the two holes on the rear side of the motor controller and
click the brackets into place with moderate pressure on both the components on the controller.
Now fit the hand switch on the table top. There are holes of ø 5.2 mm provided on the hand switch. The
tightening torque depends on the material of the table-top but must not exceed 2 Nm. *1)
Moreover, the STAND.CONTROL C1 is equipped with threaded holes of ø 6.3 mm and can be optionally
screwed to the table-top. The tightening torque depends on the material of the table-top but must not exceed 2
Nm. *1)
*1) The screws are not included in the scope of delivery since they have to be selected depending on the
material and the thickness of the desktop.

5 Commissioning
Commissioning includes all jobs that are necessary for electrical height adjustment of the FREE.STAND
sit/stand desk with the aid of the STAND.CONTROL motor controller. The prerequisites for commissioning are:
•complete assembly of the desk base in accordance with Section 4.1-4.3
•and correct installation of the STAND.CONTROL motor controller and hand-switch in accordance
with Section 4.4!
Danger: Only expert/authorised personnel are allowed to commission the motor controller!
Expert/Authorised personnel have completed the required electrotechnical apprenticeship and are
familiar with these operating instructions.
Attention: Before assembly and commissioning of the FREE.STAND sit/stand desk, make sure
the product is acclimatised for the temperature and relative humidity values stated in the technical
data!
5.1 Connections to the STAND.CONTROL C1 motor controller
Attention: Only use 2-pole power supply cables/mains cables supplied by Oelschläger
Metalltechnik.
Using other power cables can cause damage to the controller.
Attention:All connectors are designed exclusively for working with the components supplied by us.
If components or cables not supplied by us are connected, the motor controller or the connected
component can get damaged.

9051_Bedienungsanleitung_C1_Rev2_EN_UK – Stand 08.08.2018 TS / MB 14
5.2 Procedure during commissioning
Attention: Plug in the power supply cable/mains cable only after all other electrical connections
have been made! (All motors, the hand-switch and possibly additional accessories are connected
to the controller.)
To commission the FREE.STAND sit/stand desk, proceed as follows:
5.2.1 Connect the drives
Make sure that the connection cables of the drives reach from both sides up to the corresponding controller
connection. For extremely long desks, it might be necessary to assemble the controller off-centre. For especially
large desks, if necessary use an extension cable for the connection cable of the drives.
Connect the drives of the side element and the controller using the motor cable. The plug connectors on the 8-
pin motor sockets must firmly latch!
5.2.2 Connect the hand-switch
Set up the connection from the hand switch to the RJ45 socket (D1 or D2) at the controller.
Note: You can choose from a large number of hand-switches that fit the STAND.CONTROL motor
controller!
Please ask Oelschläger Metalltechnik for information on the available types!
ATTENTION: The connector (HS) serves only for operating hand switches. The RJ45 socket does
not have any other functions. If the wrong components or cables are connected, there is a danger
that the controller and the connected components can get destroyed.

9051_Bedienungsanleitung_C1_Rev2_EN_UK – Stand 08.08.2018 TS / MB 15
5.2.3 Connect the power supply cable /mains cable
Attention: Before you plug in the power supply cable, check again
•to see if the mains voltage matches the rating plate of your controller
•to see if all components are plugged into the correct sockets
The STAND.CONTROL motor controller is ready for operation as soon as the power supply cable
is plugged in!
Note: Initialisation of the desk base is required the first time the power supply cable is connected
(Reset). This is described in Section 5.
Use only the accompanying mains power cord. The controller STAND.CONTROL C1 mandatorily needs a
2-pole mains cable.
Attention: Fasten all cables to the desk base or the desktop so they cannot get damaged during
operation.
5.2.4 Installing optional accessories
There is a large number of optional accessories available for the FREE.STAND 9051 table-top support frame
(for example, CPU mounting, cable ducts, screens etc.).
These accessories are to be fitted after installing the actual table-top support frame. With some of the
accessories, it may be necessary to move the table up once, before they can be installed. In such a case,
assemble the table-top support frame as described up to point 5.2.3, and the carry out a reset in accordance
with point 5.
Thereafter, you can move the table to the required height. Isolate the table-top support frame from the mains
again and continue with the installation of the accessories.
Upon completion of the accessories installation, carry out point 5.2.3 and if required, point 5.3 (Reset) once
again.

9051_Bedienungsanleitung_C1_Rev2_EN_UK – Stand 08.08.2018 TS / MB 16
5.3 Initialisation / Reset
After the installation, or if there is a fault at the table, or after disconnecting the connection between the drives
and the controller, the controller of the table has to be initialised.
If the controller expects a fresh initialisation, the table can be moved only down, with a reduced speed. For hand
switch versions with a display,  is displayed during the initialisation movement.
For initialising, move the table into the lowermost position. To that end, press the down key on the hand switch
till all the drives have reached the lowermost position. Now, when you release the key, the table moves into the
minimal position.
Releasing the button too early can result in a malfunction at the table. If that should happen, you must repeat
the procedure.
Attention: The top limit stop of the controller is preset. For this reason, use only controllers that
were supplied as suitable for the respective desk base.
Danger: The optionally available corrosion protection is not activated during any reset process.
During this process, always watch out for the possible danger of being crushed.
6 Control
6.1 Normal operation (with all hand-switch variants)

7 Cascading 2 Controllers
2 drives maximum can be connected to one controller. To increase this number to 4, two controllers can be
cascaded.
1. To do so, 2 controllers must be configured with a parameter set for 3 or 4 drives.
2. The two controllers are connected with the RJ45 connecting cable.
3. Insert the desired hand switch into a free port.
4. Now connect the mains cable to the sockets.
5. After a reset movement, the configured number of drives will move up and down synchronously.
Attention: Use suitably configured controllers without fail, since otherwise, the cascading is not
recognised and only two drives would move, which can result in jamming of the entire system.
