1General safety information
Specified use
The drive unit is intended for vertically moving doors. The force is transmitted using a
chain. Doors that must be secured against dropping require a separate safety brake. The
drive unit can be used in hazardous areas thanks to its explosion protection according to
ATEX 2014/34/EU.
The drive unit must be protected against moisture and aggressive environmental
conditions (such as corrosive substances). The drive units are only suitable for indoor use.
Appropriate protective measures must be taken for outdoor installation. The values
specified in the technical data of the drive unit must not be exceeded. The safe operation
can only be ensured if used as specified.
Target audience of these installation instructions
These installation instructions are geared towards qualified persons trained in the handling
of door systems. Expert knowledge, relevant skills and practical experience are what set
apart qualified persons. They are capable of safely carrying out the tasks involving
installation, maintenance and modernisation according to the instructions.
Safe operation
The safe operation of the product can only be ensured if it is used as specified. Follow the
