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
installation instructions. Observe all specifications, especially warnings, when installing the
product in the overall system. GfA is not liable for damage resulting from non-observance
of the installation instructions. The resulting overall system must be reassessed for its
safety in accordance with applicable standards and directives (e.g. CE marking). These
installation instructions refer only to a part of the overall system and are not sufficient as
the sole instructions for the overall system. The installer of the system must prepare the
instructions for the overall system.
We recommend entering the danger area of the system only when the drive unit is at a
standstill.

7Mechanical installation
Warning – Explosion hazard!
 Check the atmosphere for explosion hazards before commencing installation tasks.
Requirements
The permissible loads on walls, mountings, connection and transmission elements must not
be exceeded even for maximum holding or locking torque (▶ observe technical data).
Connection elements
▶ Use self-locking
connection elements with
a minimum strength of
800 N/mm2 (8.8).
▶ Use a screw that
precisely fits the hole.
▶ Use adequately
dimensioned washers for
elongated holes.

8Electrical installation
Warning – Danger to life from electrical shock!
Disconnect the cables (mains OFF) and check that the supply is off
Observe the applicable regulations and standards
Ensure proper electrical connection
Use suitable tools
Carrying out the electrical installation
Remove the cover. Remove the cover.
Connect motor/limit switch connection cable

16
Protection against overload
Motor protection switch / motor protection relay mains operation
The "Ex" motor must be protected against overload by means of a motor protection switch or
a motor protection relay. Only use motor protection relays with manual reset. Short-circuit
protection is also required.
The excess current setting must be selected such that the motor is disconnected from the
mains within the heating time tE. The actual tripping time tA at a relative operating current of IA
/ IN must be calculated on the basis of the tripping characteristic of the excess current relay. It
must be ensured that tA < tE is given.
Completing the electrical installation
Install cable entries and/or cable glands.

17
9Limit switch setting
The limit switch setting defines the final limit positions OPEN and CLOSE.
Requirement
The door should open by pressing the OPEN
push-button of the control. If the door closes,
L1 and L2 must be swapped in a de-
energised state.
Setting of OPEN final limit position
Open to the desired OPEN final limit position
using the OPEN push-button.
Turn the cam of the S3 OPEN limit switch to
the centre of the switch plunger ①.
Tighten the screw of the cam ②.

18
Check the door position:
Close the door ① until the cam is released
and open it again ② until the OPEN final limit
position is reached.
The OPEN final limit position can be
corrected by following the fine adjustment
procedure. Check the door position after each
correction.
The S1 EMERGENCY OPEN limit switch is preset by the setting of the OPEN final limit
position. The door must stop without posing any risks should the rotating direction be
incorrect or should there be a fault with the S3 OPEN limit switch. Follow the fine adjustment
procedure to correct the switching point of the limit switch as needed.
Setting of CLOSE final limit position and auxiliary limit switch
The same setting procedure applies as for setting the OPEN final limit position.

12 Emergency manual operation (emergency hand crank)
The emergency manual operation is designed for opening or closing the door without power
supply. Its activation interrupts the control voltage. Electrical operation is no longer possible.
Warning – Injuries due to incorrect operation or falling objects!
Switch off voltage.
Adopt a secure position.
For drive units with brake, the emergency manual operation must be carried out
against the closed brake.
Warning - Danger of the door dropping!
If you need to apply more than the permissible force of 390N (according to DIN EN
12604/DIN EN 12453) to move the door by emergency manual operation, this
indicates a stalling on the drive unit or door. Releasing the stalling may cause the
door to drop.
Adopt a secure position.
For drive units with brake, the emergency manual operation must be carried out
against the closed brake.
Caution – Damage to components!
Do not move the door beyond the final limit positions.
