1.1 General Considerations
WARNING: Be aware of suspended loads.
WARNING: Wear a hard hat to reduce the risk of personal injury.
WARNING: Be careful while working with heavy loads.
WARNING: In case of optical radiation emergency, please disconnect the device from the mains
current; this by employing the mains switch. In case the mains switch is not easily accessible, the
projectors shall be disconnected by other means for example the mains junction box.
It is advised to employ the shutter or select a black image on the projector in order to reduce the risk
of the emergency.
WARNING: Mind your fingers while working with heavy loads.
General safety instructions
• This product contains no user serviceable parts. Attempts to modify/replace mechanics or electronics
inside the housing or compartments will violate any warranties and may be hazardous.
• Do not stare into beam when the projector is on. The bright light may result in permanent eye damage.
• Before operating this equipment please read this manual thoroughly and retain it for future reference.
• Installation and preliminary adjustments must be performed by qualified Barco personnel or by authorized
Barco service dealers.
• All warnings on the projector and in the documentation manuals must be adhered to.
• All instructions for operating and use of this equipment must be followed precisely.
• All local installation codes should be adhered to.
Notice on safety
This equipment is built in accordance with the requirements of the applicable international safety
standards.
These safety standards impose important requirements on the use of safety critical components,
materials and insulation, in order to protect the user or operator against risk of electric shock and energy
hazard and having access to live parts. Safety standards also impose limits to the internal and external
temperature rises, radiation levels, mechanical stability and strength, enclosure construction and protection
against the risk of fire. Simulated single fault condition testing ensures the safety of the equipment to the user
even when the equipment's normal operation fails.
Notice on optical radiation
This projector embeds extremely high brightness (radiance) lasers; this laser light is processed through the
projector's optical path. Native laser light is not accessible by the end user in any use case. The light exiting
the projection lens has been diffused within the optical path, representing a larger source and lower radiance
value than native laser light. Nevertheless the projected light represents a significant risk for the human eye
and skin when exposed directly within the beam. This risk is not specifically related to the characteristics of
laser light but solely to the high thermal induced energy of the light source; which is equivalent with lamp
based systems.
Thermal retinal eye injury is possible when exposed within the Hazard Distance (HD). The HD is defined from
the projection lens surface towards the position of the projected beam where the irradiance equals the
maximum permissible exposure as described in the chapter
“ Hazard Distance ” .
When installing an interchangeable lens with a throw ratio that make the projector become an RG3
unit, (See the chapter
“ Approved Lenses ” in the installation manual), refer to chapter “ HD in function
of modifying optics ” , page 209 regarding precautions.
