Electrical installation for 12 external roller shutters - how do I connect the switches?

Question

Colleagues, please help. I am planning to install 12 roller shutters, I have a 5x1.5 cable and I plan to lay it this way: a cable from the distribution board to the first main switch, then from it to the 6 roller shutter switches which I will connect in parallel, from each switch to the motor of...

. I deduce that you want to have control of each roller shutter separately and in addition from the main all at the same time ? Something about this and here

Looking at the diagram in the second link I plan to do the same only if I make two such circuits as shown in the diagram and connect them with two master switches will it work normally ?

kokapetyl · Answer

. In the link provided, you have a number of solutions, such as a multi-zone installation and an additional extended one. You need to analyse them and choose the right layout.

And another question is it possible to control three roller shutters from one switch? Because I have a bay window with three windows and I would like to control this from one switch instead of making three separate ones. Because normally I don't think it's possible.

kokapetyl · Answer

Yes, it is possible (roller shutters connected in parallel under the control), but you have to be careful when installing these roller shutters (keeping the directions of rotation)
Typical roller shutters have limit switches and each will switch off at the appropriate time.

tobiasz91 · Answer

In parallel under the control unit, i.e. power from the switch to the first roller shutter and from there to the next etc.?

kokapetyl · Answer

. Not quite. From the switch to each roller shutter, not from roller shutter to roller shutter. You may be thinking along the same lines, but your description suggests a series connection, and it is supposed to be in parallel.

kkas12 · Answer

. This is not a series connection, but don't deprive yourself of the ability to control each roller shutter individually. Each roller shutter should have its own up, down buttons.

And now one more question, maybe silly, but zaytam how much cord stock to let out? Well, because I don't really know which side of the roller shutter will have the motor. Or is it just possible to connect both sides? Or will the roller shutter already have its own spare cable?

kkas12 · Answer

Roller shutters usually have a motor with a lead. You should take this into account so that it does not turn out to be too short if you miss the switch box.

kokapetyl · Answer

. In this case, two mounting boxes are made (on either side of the window/door), the wiring is fed into both, and you will use the one that will fit under these roller shutters.

kkas12 · Answer

??? Install the roller shutters first and only then get down to powering them, or agree and specify in the roller shutter order exactly what you want instead of duplicating the installation .

kokapetyl · Answer

. This is probably unrealistic, the installations are done well before the roller shutters are fitted. Fact, the type of roller shutter needs to be known beforehand (if possible) and then we don't have the problem of where its drive will be.

kkas12 · Answer

Is this some kind of binding rule, or just a colleague's idea of construction? Why negate the installation of the joinery and the bonding of the polystyrene/wool and only then the installations inside. And if Styrofoam/wool then there must be roller shutters. Nowadays this is very often the order .

kokapetyl · Answer

. I'm not negating it, you can still do it, but the duration of the investment will be much longer, won't it ?

kkas12 · Answer

What do you care about investment time?
And doing the installation before the carpentry is stupid.

To the author of the thread, it should also be added that the cable between the roller shutter and the box should be laid in a pipe. It doesn't matter whether it is laid inside or outside the building.
This will pay off when the roller shutter drive unit needs to be replaced.

kokapetyl · Answer

. Me? Absolutely nothing.

tobiasz91 · Answer

As far as the box is concerned, should I make one deep box for the switch and the connection to the roller shutter motor or two, i.e. one with the switch and one for the connection between the switch and the roller shutter?

kkas12 · Answer

What two boxes? You install a fi 60 deep box, feed it with a 5x wire and drain it with the same wire to the next box for the next roller shutter and of course the wire for the drive.

tobiasz91 · Answer

and this is how I plan to do it. Because I have seen that some people still do a box between the switch and the roller shutter. But if I have a deep box I can fit everything in it. I will ask again if it is correct if I make 7 roller shutters on one circuit and 5 on the other and connect the two central switches together, then I can control all of them at once from these two central switches. Because I would not like to have any surprises once the plaster has gone on the walls .

kkas12 · Answer

For this kind of control you have to put a hundred in each switch box. Plus what's under the central switch.

tobiasz91 · Answer

I have come into possession of a5x1.5 wire but black in rubber. Is it suitable for plastering these roller shutters or should I buy white PVC?

Marek J. · Answer

Hi. Since future forumers may be looking for solutions to their problems in this topic.... . Do not connect several ordinary roller shutter motors in parallel under one switch or control. . Each motor must have a separate controller/module which can be connected under one G/D switch.
