"To answer your question: if there is a power failure while the saw is
running, the cartridge might stay powered for about 1-2 seconds at most
while its internal voltage falls off.

So under those conditions (saw coasting down, no power to saw at all)
touching the blade would not activate the safety system."



So here is how I read this. If the lights go out you try not to
continue sawing. In the event you are very close to the blade while
cutting and the power fails the blade is going to stop more quickly and
the brake may activate before the blade stops.
