Never use the DuoFern Radio System and its components for the remote control of appliances
and systems with increased safety-relevant requirements or where there is an accident risk.
• Applications of this kind require additional safety equipment. Observe the respective statutory regu-
lations for the installation of systems of this kind.
6. Expert knowledge required of the installer
The installation, electrical connection and maintenance must be carried out by a qualified person with
appropriate training or by a specialist roller shutter firm in accordance with the instructions in the
operating and assembly manual (link to the website, see cover page).
7. Safety functions
Blockage detection
Moving a blocked (e.g. iced-up/jammed) roller shutter may overload and damage the tubular
motor and roller shutter system.
• Do not move the iced-up/jammed roller shutter and rectify the fault or remove the obstacle.
8. Safety instructions for the installation
Preparation for the installation
• Never dismantle the stoppers from the final roller shutter slat. Otherwise the roller shutter may slip
through into the roller shutter box and be damaged.
Risk of fatal injury from crushing in the event of operation without set end points.
• The end points must be set in order to ensure safe operation.
Incorrect installation can lead to injuries (impact injuries and contusions).
• The motor can eject from the drive bearings in the event of incorrect installation/fastening. Fasten the
tubular motor with the securing devices provided.
Installing the tubular motor at an angle can cause the tubular motor or roller shutter to be
damaged. For example, a roller shutter wound at an angle can block the drive and cause
damage.
• Always ensure that the tubular motor and bearings are mounted horizontally.
• Please ensure that the winding shaft and the roller shutter can move down easily and freely after the
installation is complete.
• The roller shutter may not run over the bearings, the roller capsule or the drive head during operation.
• Ensure that the winding shaft and the rigid shaft connectors do not touch the drive. They may not rub
against the tubular motor during operation.
