Burning of Satel ASW-210, ROPAM RM5-12V-1P modules when controlling 230V GU10 LED lighting

Good morning!

I would like to raise the following issue and get your opinions.

There are two façade lighting lamps, in them 2 LED 230V GU10 bulbs of 10W each.
Controlled from the integra by an ASW-210 relay and the other point by a Ropam RM5. Relays concealed in flush-mounted boxes.

At both points the modules burned out as shown in the photo. The light was switched on from a timer at night time. It was not used excessively. The damage occurred non-simultaneously but fairly soon after the system was up and running i.e. 2-3 weeks. I would add that other points on Relpol RM85 relays are ok, same light sources everywhere.

What could be at fault in this situation ?

?

Atmospheric discharge or switching overvoltage in the installation?
I assume that the N in the installation was not missing because the losses would have been more extensive....
Another pathway is dampness/flooding of the controllers.
Greetings. J.
