2.0 Safety instructions
2.1 General information
The electro-mechanical GRASS Sensomatic drawer system is a state-of-the-art system complying with the appli-
cable EU standards and general accident prevention regulations. Certain risks, however, remain in case of non-
compliance with these operating instructions. GRASS GmbH does not accept any liability or claims under warranty
for damage or subsequent damage resulting from noncompliance with these operating instructions.
The Sensomatic drive units are subject to the regulations of the Machinery Directive 2006/42/EC (MD for short).
The Grass Sensomatic is a complete machine - see the Machinery Directive guidelines (edition 2.2.) The requi-
rements of the Machinery Directive are fulfilled by the Grass Declaration of Conformity if the Sensomatic unit is
installed in furniture in compliance with the current Grass specifications (catalogue, operating instructions, assem-
bly instructions). If the furniture deviates from these specifications, the party placing the furniture on the market
must ensure its conformity.
The scope of the Machinery Directive covers distribution within the European Economic Area (EEA), Switzerland,
Turkey and Northern Macedonia. The requirements of other countries are covered by certifications.
2.2 Safety instructions for assembly
GRASS Sensomatic opening systems may only be assembled by trained specialists with the help of these
assembly instructions.
All work must be performed whilst disconnected from the electrical supply.
Adhere to national regulations and standards when assembling Sensomatic system.
GRASS GmbH excludes all liability for unauthorised changes to GRASS Sensomatic opening systems and
any resulting damage.
GRASS GmbH provides a warranty only for the drawer and slide systems Nova Pro, DWD XP and Dynapro.
However GRASS GmbH cannot accept any liability for combinations with products of other manufacturers.
Use only genuine GRASS parts for repairs and maintenance.
The system must be connected to the power supply by a qualified electrician.
When sawing in the vicinity of GRASS Sensomatic systems, ensure that no sawdust gets into the drive unit
or into the guide rails.
It must be possible to isolate the opening system, e.g. using switchable sockets. Prior to changing the power
supply unit or the opening unit, the system must be isolated.
Do not squeeze cables or allow them to come into contact with moving parts.
The power supply unit must be easily accessible.
Ensure that no moisture can enter the power supply unit.
Do not use damaged parts.
When the power supply unit is connected, the extension arm moves to the home position.

2.4 Repairs and modifications
Repairs and structural changes to the „GRASS Sensomatic“ opening system may only be carried out by an
authorised specialist. The declaration of conformity issued by Grass is based on a risk assessment of stan-
dard kitchen units. If furniture is not manufactured in accordance with the Grass catalogue, operating instruc-
tions and assembly instruction specifications, conformity must be certified by the party placing the furniture
on the market. This means that the furniture manufacturer is therefore obliged to prepare a risk assessment
for the installed furniture, to prepare and keep the technical documentation, to fill in and sign a declaration of
conformity, to ensure CE marking on the furniture (fill in and affix the type plate) and to forward a user manu-
al and a copy of the declaration of conformity to the customer in the customer‘s national language.
Live components!
Never open the power supply unit or an opening unit!
3.0 Functional description
A drawer can be opened by tapping or by pulling the handle (if applicable). The opening unit supports opening the
drawer as the opening lever pushes the drawer forward. When leaning against the drawer, it cannot be opened!
GRASS Sensomatic facilities a smooth and gentle action when closing the drawer.
Note: It is not permitted to install the Sensomatic in conjunction with an internal drawer
driver. When installed with an inset drawer, do not use an internal drawer driver.
