Please keep these operating instructions for future reference and maintenance. 

Subject to technical modifications. Diagram is not binding.

For further application, please contact SE Controls. 

The actuator compiles with current safety directives.

Operating safety can be guaranteed only if installers comply 

with the safety regulations in force in the country where the 

actuator is used.

The actuator is not a structural member of the window. 

Always mount the safety arms in bottom-hung applications. 

The position of the three-way switch button must be 

outside the field of action of the moving part of the window.

Do not allow children to play with the fixed or remote 

controls.

When using the actuator, follow these safety       

instructions described herein. This equipment 

is designed for the automatic opening and 

closing of the stated types of windows.

Do not install two or more actuators on the 

same window without using a synchronisation 

accessory.

Any other application of the actuator must 

be approved after technical testing of the 

application. Use only original accessories or 

accessories approved by SE Controls to install 

the actuator.

When opening or closing the window, make 

sure other people are far away from the moving 

part, even when a fire detection system is 

closing an open window.

1.4 Application and Use

It would be beyond the scope of these safety instructions 

to list all the valid regulations and guidelines.

Always make sure that your system 

corresponds to the valid regulations. Pay 

particular attention to: the aperture cross-

section of the window, the opening time and 

opening speed, the temperature resistance of 

the cables and equipment, cross-sections of 

the cables in relation to the cable lengths and 

power consumption.

Care must be taken to ensure that actuator 

products are controlled with compatible 

products; refer to SE Controls. No liability will 

be accepted and no guarantee nor service is 

granted if actuator controls are used without 

such compatibility being confirmed.

Installation of this equipment must only be carried out by 

authorised, competent and safety conscious persons.

Routing of cables and electrical connections only to be 

done by a qualified electrician.

The cables must be installed in such a way that they cannot 

be severed off, twisted or bent off during operation.

Junction boxes must be accessible for maintenance work.

1.5 Installation

The actuator must be assembled and 

connected only by specialised staff who have 

been properly trained and who are familiar 

with the problems associated with automatic 

window opening and closing systems, technical 

reference standards and safety standards.

The window closes automatically. When 

opening and closing, the drive unit is stopped 

by the power cut- off. The corresponding 

pressure force is listed in the technical data.

Take care - the pressure force is high enough to 

cause injury!

During assembly and operation do not obstruct 

the window opening! 

 

 

Danger of crushing/trapping!

Warning! Incorrect installation may render the 

actuator dangerous! Follow all the instructions 

set out below and the instructions applied to 

the motor.

Power supply leads 230 V AC to be fused 

separately by the customer. Keep power supply 

leads sheathed until the mains terminal.

All low voltage cables (24 V DC) to be installed 

separately from high voltage cables. Flexible 

cables should not be plastered in. Provide 

strain relief for freely suspended cables.

Adhere to the type of cables, cable lengths 

and cross- sections as stated in the technical 

information.

After installation and any changes to the system check all 

functions by a trial run.
