RG2 IEC 62471-5:2015.
Hazard distance (for non-US installs)
Refer to the table T-1 in Supplement (at the back of this manual). The table
shows the hazard distance in which the beam strength described in IEC 62471 - 5
(Photobiological safety of lamps and lamp systems – Part 5: Image projectors) is
categorized as RG3.
For the combination of the lens and projector for which a value is shown in the
table, when the projection distance is the value or shorter the beam strength is
categorized as RG3, and is a hazard.
When applying the combination shown in the table, "operators shall control
access to the beam within the hazard distance or install the product at the height
that will prevent exposures of spectators' eyes within the hazard distance".
Refer to the F-9 in Supplement (at the back of this manual).
