A first for me to see this. Some may know it well? I'm use to the other rain bird rc mech controller In any case I was at a restaurant- system hadn't been touched in years. This controller was just hanging off the wall . I freaking bumped it and all of a sudden sparks start -a flying! 2 Rooms over I'm hearing screams ! A gfi popped off and shot some sparks too. I was pissed .. serious code violation. ... The wires were just disconnected in the back of the controller only half a inch from eachother and they were live... Got a new controller in- used a different plug and circuit..
