positioning the device; in particular, the device must be installed in

interrupting the protected field.
To exclude the possibility of the machine being accessed from above
or below (Fig. 3a), it is necessary to install a safety light curtain that is
long enough to completely cover access to the danger zone (Fig. 3b).
