Installation

5.1 Safety notices to observe during installation
Basic safety rules must be followed in order to ensure that the end product can be continually operated in a safe manner. These rules must be observed while using the end product and while installing the control unit, the handset and the lifting columns in the end product.

5.1.1.1 Avoiding electrical faults
Be sure to consider the length of the power cord when designing the dimensions for your end product in order to minimize the associated risks.

5.1.1.2 Routing the electrical cables
When routing the cables, be sure that:

• The cables cannot get jammed or damaged.
• No mechanical load (such as pulling, pushing or bending) will be put on the cables.
• All cables are secured using sufficient strain relief and kink prevention methods.

5.1.2 Reliability
The safety and reliability of the end product containing DewertOkin components can be ensured by using the proper construction methods as described below.

5.1.2.1 Overheating
A thermal monitor switches the control unit off if it overheats.

CAUTION
The control unit is equipped with a thermal monitor (circuit breaker) that triggers when the unit overheats. If this has triggered, remove the control unit from the power supply and allow it to cool down. Wait for about 15 minutes and reconnect. If the control unit still does not function, please contact your supplier or sales agent.

5.1.2.2 Avoiding fatigue fractures
Install the lifting column in the end product so that it is properly aligned. This will help prevent shear stress.
Do not position the 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 lifting column’s direction will create shear stress and could lead to a fatigue fracture.

5.1.2.3 Avoiding a pinching hazard
When designing your product, you should take the lifting column’s adjustment movement into account with passive safety mechanisms and with the appropriate safety notices in your operating instructions.
Install the lifting columns so that none of the positions where shear and pinch hazards exist are accessible externally. This will ensure passive safety. Make sure that your operating instructions inform the user of these hazard points.
Structural modifications and improper installation which do not follow the installation steps or the safety instructions found in these installation instructions may result in serious injuries. Structural modifications may only be made after consulting with and receiving consent from DewertOkin.

NOTICE
Compliance with the intended usage and other regulations
Any further processing of the products that contradicts the proper and intended usage is forbidden. The manufacturer or installer of the end product must ensure that all legal and regulatory requirements regarding the end product’s manufacture, installation and customer support are followed.

5.1.2.4 Verifying the product code
Check that the product code matches your specifications: The system’s product code is in the format DSx.yyy.z, whereby: x = desk system type (number of columns per desk) yyy = lifting column type z = number of sections (2 or 3 telescoping sections) in the lifting column Thus, the system product code DS2.DD351.2 designates a system with two columns, using the 351-type lifting columns, with 2 inner telescoping sections per column

5.1.3 Selecting the tabletop
The DIN Technical Report 147 describes the following information:

• Corner and edge design
• Exterior surfaces
• Surface brightness
• Surface finish
• Min. 3 mm edge radius

This information shall be considered binding when selecting the tabletop.

5.1.4 Ergonomics
