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. 5 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 a
sufficient height in order to completely cover the access to the
dangerous area (Fig. 6) becomes necessary.

Fig. 6 – Correct device positioning
Under standard operating conditions, machine starting must not be possible while operators
are inside the dangerous area.
When the installation of the safety light curtain very near to the dangerous area is not
possible, a second light curtain must be mounted in a horizontal position in order to prevent
any lateral access, as shown in
Fig. 8
.
If the operator is able to enter in the dangerous area, an additional
mechanical protection must be mounted to prevent the access.
