1 General 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 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 drive unit is not intended for
hazardous areas. 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.
Warning – Failure to follow these installation instructions may result in severe injury or death.
- Please read these instructions before using the product.
- Keep these instructions handy.
- Include these instructions when passing on the product to third parties.
Warning – Danger from improper use of the product!
- Do not let children operate the product unsupervised or use as a toy.
Warning – Danger to life from incorrect installation!
Work carried out improperly may result in death or severe injury from electrical current or falling parts.
- Allow only competent people to carry out the work.
- Disconnect all cables from the power supply.
- Observe valid regulations and standards.
- Use suitable tools.
Warning! Danger to life from falling objects if the drive unit is subjected
to impermissible forces.
Inadmissible forces (examples: collision with a forklift, dropping the drive
unit, tearing or pulling on the motor) lead to damage to the drive unit. There
is a risk of severe injury or death from falling objects.
- Prevent impermissible forces from acting on the drive unit,
- Check the drive unit for damage if impermissible forces have acted on it. Look even for minor damage. Lock the door during the inspection.
- Contact the service department if you have difficulty assessing the damage.

Mounting
Four elongated holes are provided for mounting.
Installation
The descriptions below apply to general door specifications. The specifications of the door manufacturer must also be observed during installation.
Warning – Potential injury or danger to life!
- During installation, be sure to use a lifting device that has a sufficient loadcarrying capacity.
• Thoroughly grease the output-shaft.
• Install (1) and secure (2) the chain wheel. Do not tighten yet. Install (3) and secure (4) the output-shaft on the right or left.
• Mount the drive unit. Tighten the connection elements to 75 Nm.
• Position the chain wheel (1) properly. Install the chain wheel (2). Secure the chain wheel (3).
• Tighten the chain wheel properly (1). Tighten all connection elements (M12) to 75 Nm (2). Install all other connection elements according to the specifications of the door manufacturer.
4 Electrical installation
Warning – Danger to life from electric current!
- Switch the mains OFF and check that the cables are de-energised
- Observe the applicable regulations and standards
- Make a proper electrical connection
- Use suitable tools
Performing electrical installation
| Remove the cover. | Insert the motor plug. | Insert the limit switch plug. |
|---|---|---|
| 
Completing the electrical installation
Mount the cable entries and/or cable glands.
5 Limit switch setting
The setting of the final limit positions OPEN and CLOSE is described in the instructions for the door control.
The door control must meet Performance Level c!
Use only door controls that evaluate the limit switch according to EN 12543 and meet Performance Level c.

9 Emergency manual operation (hand chain operator)
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!
- 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.
Switch on by pulling the red handle. Open or close by pulling the chain. Switch off by pulling the green handle.
10 Completing commissioning / inspection
Check the following components and then install all covers.
Gearbox
Check the drive unit for loss of oil (a few drops can be neglected). Protect
the output-shaft permanently against corrosion.
Mounting
Check that all connection elements (consoles, torque mounts, screws, locking
rings, etc.) are secure and in proper condition.
Electrical wiring
Check the connection cables and cabling for damage or crushing. Check that the
screw connections and plug connections are fitted properly with a good
electric contact.
Emergency manual operation
Check the function with the power disconnected. Perform the check only between
the final limit positions.
Limit switch
Check the final limit positions by opening and closing fully. The safety area
must not be approached.
Brake
Warning – Potential injury or danger to life!
- Carry out a brake test. Overrun depends on the door and its equipment. The specifications of the door manufacturer must be observed.
- Brake lift may only be used in the final limit position CLOSE for doors that have no counter-balancing.
Warning – Potential injury or danger to life!
Lifecycle brake – change complete brake unit at:
- Operation with mains supply after 250.000 cycles
- Operation with Inverter after 1.000.000 cycles
In an environment that can affect the coefficient of friction of the brake pad (atmosphere with oil, solvents, detergents, etc.), class of protection IP65i must be adopted.
Drive unit
Note!
- Engage a qualified engineer to check the drive unit annually
- Apply shorter inspection intervals for doors that are operated frequently
- Observe the applicable regulations and standards
