5.4 Installing the SMART/COMPACT control units
NOTICE
When installing the control unit, take into account the thickness of the tabletop.
Mount the control unit under the centre of the table. The best installation position is between the
table frames. Be sure to note the length of the connecting cables during the installation.
Use 4.8xL raised-head screws (according to requirements of DIN 7981) with a 9.5 mm head di-
ameter and of suitable length (2 mm + screw-in depth into the table). Tighten the screw using a
maximum
torque of 2 Nm.
CAUTION
You should only install and uninstall the control unit when it is completely disconnected from any
live current!
Mount the control unit as shown in Figure 35 (for the SMART) or Figure 37 (for the COMPACT):
1
Mark the drill holes. The positions of the holes are shown in Figure 34 (SMART) or Figure 36
(COMPACT).
2
Use a suitable drill to drill the two holes.
3
Screw the control unit onto the tabletop.
4
Route all connecting cables under the tabletop so that they cannot be pinched during the table's
lifting movements.
