follows.

A qualified person, as determined by local regulations, must confirm that
installation and inspection are implemented correctly.
Do not use the F3SP on machines that cannot be stopped by electrical control in
case of an emergency, such as a pressing machine with full-rotation clutch
system. Serious injury may result if the machine does not stop before someone
reaches the hazardous part.
Muting sensors must be positioned so that they cannot be activated inadvertently
by personnel.
