Shelly 3EM short circuit due to wrong relais wiring - Devices

I had my Shelly 3EM installed by a professional electrician today. Worked fine. All 3 phases gave the correct output. The 3EM was just connecte to 3 phases to a simple plug where my washmashine und tumbler are connected. They were both off. I then added the 3EM to my Homey. Then I tapped on the icon, when I hear a “bam” and the 3EM exploded/burst into two pieces. What is the “press” on the “3EM” Icon activating? What is the function when pressing the 3EM Icon? (For lights, it will turn on/off

Shelly support group (English Version), So, 3EM arrived yesterday, and with device and user guide in front of me, I'm still unsure how to connect
