Special instructions: Please do not place sharp-edged objects or objects with abrasive surfaces on the finished surface to avoid unwanted scratches. Melamine resin-coated surfaces / HPL compact board Plastic-coated surfaces consist of resin-impregnated decorative papers and are characterised by very high wear resistance. Although liquids cannot penetrate the material, soiling or stains must be wiped away immediately.
Special notes: Particularly in the post-oxidation phase, a "yellow cast" develops on linoleum. This is particularly noticeable in light colours, but disappears completely when exposed to UV light, and the linoleum reverts to its original colour. On the other hand, this "yellow cast" reappears if, for example, the surface of the covering is covered with monitors, mouse pads, etc.

Then mount the panel support to the crossbar with the M8 screws according to the frame drawing through the threads in the installation column. The max. tightening torque for these screws is 10 Nm. Optional CPU holder: Then mount the plate carrier and CPU holder to the crossbar with the M8 screws through the threads in the built-in column as shown in the frame drawing.
5) Assembly of the manual switches Now mount the handset on the table top using the fixing material supplied (screws in a labelled bag). Holes or screw points are provided for this purpose on the handset and in the top. Stick the cable clip onto the table top and thread the cable in.

INITIALISATION / RESET After assembly, or if the table has been disconnected from the power supply for a period of time and there has been a malfunction with the table; or if the connection between the drive units and the control unit has been disconnected – the control unit of the table must be initialised. If the control unit requires a fresh initialisation, only the downward movement of the table, with a reduced speed, is possible.
To deactivate a container or shelf stop position, proceed as follows: • Move the sit-stand table to any position in the lower half of the travel range to deactivate the container stop or to the upper half of the travel range for the shelf stop position.
CLICK CODES OF THE CONTROL UNIT As soon as power is supplied to the motor control unit, the control unit uses the built-in relays to inform the user acoustically about the system status; and in addition, informs about the reason of the last shutdown.
TESTS AND CERTIFICATES The drive system is tested according to: Electromagnetic Compatibility (EMC Directive 2014/30/EU). • EN 61000-6-2:2005 Electromagnetic Compatibility (EMC) • EN 61000-6-3:2007 + A1 Electromagnetic compatibility (EMC) • EN 61000-3-2:2006 + A1 + A2 Electromagnetic compatibility (EMC) • EN 61000-3-3:2008 Electromagnetic compatibility (EMC) Electrical safety (Low Voltage Directive 2014/35/EU) •...
