6. Installation
6.1 Safety notices to observe during installation
Basic safety rules must be followed in order to ensure that the end product can be continually oper-
ated in a safe manner. These rules must be observed while using the end product and while in-
stalling the DC20 lifting columns.
6.1.1 Ensuring operational reliability during installation
The safety and reliability of the end product containing the DewertOkin drive can be ensured by
using the proper construction methods described below.
Avoiding fatigue fractures
CAUTION
DC20 lifting columns that are incorrectly installed can undergo fatigue fractures which
then create a risk of injury.

Install the DC20 lifting column in the end product so that it is properly aligned. This
will help prevent shear stress.

Do not position the DC20 lifting column at a slanted angle when installing it in the
end product. A slanted angle between the intended direction of movement of the
end product and the DC20 lifting column's direction will create shear stress and
could lead to a fatigue fracture.

Be sure to install the DC20 lifting column so that it can always move freely in all op-
erative states.
Avoiding a pinching hazard
CAUTION
The drive movement is executed by the telescopic column. When designing your prod-
uct, you should take this into account with passive safety mechanisms and with the ap-
propriate safety notices in your operating instructions:

Installation methods for ensuring passive safety: Install the DC20 lifting column so
that none of the positions where shear and pinch hazards exist are accessible ex-
ternally.
When preparing safety notices for the operator, Make sure that your operating instructions inform
the user of these safety points.
