Get an 11+ pin plug something like a Harting (other makes are available) and run the e-stop system through the plug too, that way it has to be plugged in to allow the system to start, unless you have a dummy plug, plus you can get the right pins so they break correctly to e-stop before they break the power connections.
Oh and you can also get coding pins so that they can only be fitted in the right way and the right place, unless you re-configure the plug, but then that can be said of any plug which can be opened up.
