●The below table describes the radiation zone of emitted light by the projector that is classified
as Risk Group 3 (RG3) of IEC/EN 62471-5 First edition 2015.
● Please keep within bounds for installing the projector.
Install a barrier for preventing human eyes from entering the RG3 zone. For the barrier instal-
lation position, keep horizontal security zone over 1 m from the RG3 zone. In case to install
the projector over head, keep over 3 m distance at least between the floor surface and the
RG3 zone.
This projector must be installed at a height that will prevent your eyes from being exposed
within the RG3 zone.
The equipment administrator (operator) must control the entry of viewers into the RG3 zone.

The drawings below are example of typical installation methods. Besides these, when installing the
