Sorry, there are only really 3 additional items to your drawing. I'm a believer in breaking down the 30a or 50a circuits to less dangerous amperages, hence the breakers in line. The estop can be a 2-way switch or a locking mushroom switch, whatever you desire.
The PID drives the SSR on the low voltage side, while turning on and off the high voltage side. On the 220v side there is a 2-pole contactor. The contactor is another fail safe. With it, you can physically shut off your element without having to cut the power to the entire panel, this is smart for your own safety, and for the element. While an SSR will shut off your element, it doesn't completely cut off the current, there is still leakage, whereas the contactor will cut power completely.
I did however, miss your PID on/off switch, this can be added inline on the hot side easily though.
Hope this helps.
