Danger!
To avoid injury, the following points must
be observed:

carried out from a safe standing position.
- Emergency operation may only be
carried out when the motor is stationary.
- The system must be disconnected from
the power supply during emergency
operation.
- Operators with a spring brake must be
actuated against the closed brake when
opening or closing the door.
- For safety reasons, brakes in doors
without a weight counterbalance must
only be released in the closed door
position for testing purposes.
- Accidental releasing of the brake must
be rendered impossible by preventive
measures at the installation site.
During maintenance works or in the case of an electrical
failure, the door can be moved towards the OPEN or
CLOSED positions with the help of the emergency
manual override equipment.
Information:
If the door is moved beyond the CLOSED
or OPEN end positions, the operator
