    Faac c721 shorting power on mains

    Thank you, all these replies are so useful! No, there are no signs, as far as I can tell, of water having leaked into the enclosure, although there is the possibility that some foreign object such as a bug or snail might had created a contact between the pins of the board. I will for sure put...

    Faac c721 shorting power on mains

Except for the motor and the screws that hold it onto the bottom plate, i would say the whole enclosure is made out of plastic. The bottom connectors of the board are exposed though, as...

I used a specific tool and they seem to be tight, it is good practice to used these on this type of connector? I am thinking of the...

    Faac c721 shorting power on mains

    Hello, I have a similar problem with a different model of gate opener (FAAC 740d). The reason for shorting the mains in my case turned out to be a blown circuit board. Besides having to replace the board I would like to know if there is anything I can do to prevent this from happening again in...
