How to Connect Radio-Controlled Roller Shutters Without Installation Boxes?

Hello, I don't know if the topic has already been discussed. If so, please provide a link
This is about connecting the power supply to radio controlled roller shutters. There is a 3-wire cable 2.5 metres long from the roller shutters.
The instructions show the following connection .
All clear, but where to put this connection if there will be no installation boxes as the roller shutters will be controlled from the remote control. You can't leave something like that in the wall after all. You could be tempted to remove the factory cable and plug directly into the roller shutter. But that would risk voiding the warranty.

Extending the factory cables from roller shutters is nothing new. I myself always wonder whether manufacturers could not simply supply the drives themselves, for example, as an extra option when ordering? What are these cables for. I understand the warranty etc., but...

To the point:
1. at the point where the cable enters the building, usually right next to the window, there is a standard 60mm box, but cast in such a way that the plaster covers it. You cover it with a cap and the plasterers plaster it. You have a connection where you can access it - take photos with a meter and know where to look for faults.
2. through sleeves + heat shrink with glue and into the plaster.
3. soldering + heat shrink with glue and plaster.
4. I've come across installations where solution 1 was used but using 80-gang boxes and the customer then had the lid on the wall because he didn't mind. A matter of taste.
5 I have also encountered the installation of boxes from point 1 in window recesses. In this case, any chipping off and repainting of the wall is limited only to the recess itself and there is no difference in the texture of the plaster or the colour with respect to the entire wall.

Happy! .

- in terms of the warranty, still check that the condition is not connection by a person with the appropriate Qualification Certificate (so called SEP authority) confirmed by an entry in the warranty card. From reading your questions I suspect that you do not have such ...

This cable is not permanently installed for no reason - it is a matter of maintaining the protection class and IP tightness in accordance with the regulations - the manufacturer is responsible for that - an external roller shutter is exposed to weather conditions and the appropriate IP must be maintained. If it were demountable, it might no longer be eligible.

The method of connection is also to a large extent determined by the applicable regulations. Take a look at the applicable standard - PN-HD 60364.
Connections of conductors (apart from switchboards and other such devices) should be made in accessible boxes using crimped or screwed connectors. That is, without soldering, plastering boxes and other such ideas commonly used in times gone by.
On top of this, you also have regulations specifying protection requirements (e.g. number of consumers per overcurrent protection) - the question of the power supply to the roller shutters.

Generally, the connection is best made in the box under the switch or socket - it depends on the situation - e.g. you use a deepened box, if necessary, and there you connect the wires with twisted or popular Wago connectors. In the case of roller shutters with switch control, you can make the connection there; if the roller shutter has such connections, you can install the box, make the connections there and install the controller/switch in this box. The remote control can be lost/burnt/destroyed/broken, batteries run out on a Saturday night, etc. - it is better to leave the possibility of manual control.
