General information
Only a DewertOkin device should be used to control the DC20 lifting column since they have
already been verified to work together.
Power-on time / intermittent operations
The DC20 lifting column has been designed for intermittent operations. Intermittent operation is an
operational mode where the DC20 lifting column must pause after a specified maximum period of
operation (power-on time). This protects it from overheating. Extreme overheating can cause a
malfunction.
The ratings plate specifies the maximum power-on time and the required pause intervals.
Avoiding electrical risks
WARNING
Make sure that all live (current-carrying) parts of the drive system and power supply
cannot be touched. In particular, be sure that unused power and control unit connec-
tions are covered adequately.
Avoiding cable damage
Be sure that your operating instructions inform the user about the possible cable risks.
CAUTION
The cables (particularly the connecting cable) should not be run over. In order to pre-
vent injuries or damage to the DC20 lifting column, no mechanical strain should be
placed on the cables.
