2.2. General information on device positioning
The safety light curtain should be carefully positioned, in order to
reach a very high protection standard. Access to the dangerous area
must only be possible by passing through the protecting safety light
beams.
Fig.5a shows some examples of possible access to the machine
from the top and the bottom sides. These situations may be very
dangerous and so the installation of the safety light curtain at
sufficient height in order to completely cover the access to the
dangerous area (Fig.5b) becomes necessary.
