Lost connection and capacitor C1 very hot #20

After letting it work for some time, connection to EMS-Bus is lost and one capacitor is getting very hot. It's C1 on the pcb. I disconnected the board asap from the service connector jack, Connecting it again for only 2 swconds it's hoz again. I think a part on the pcb is damaged. I'm really frustrated that it only worked for a very short time. What could be happened to cause this?
