Barco UDX 4K22 Installation Manual page 11

To prevent personal injury
• To prevent injury and physical damage, always read this manual and all labels on the system before powering the projector or
adjusting the projector.
• To prevent injury, take note of the weight of the projector. Minimum 4 persons are needed to carry the projector. The projector
weights about ±92 kg (±202 lbs) without lens and rigging frame.
• To prevent injury, ensure that the lens and all covers are correctly installed. See installation procedures.
• Warning: high intensity light beam. NEVER look into the lens ! High luminance could result in damage to the eye.
• Warning: extremely high brightness projector: This projector embeds extremely high brightness (radiance) lasers; this laser
light is processed through the projectors 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 when exposed directly
within the beam. This risk is not specific related to the characteristics of laser light but solely to the high thermal induced energy
of the light source; which is comparable with lamp based systems.
Thermal retinal eye injury is possible when exposed within the Hazard Distance. The Hazard Distance (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 "High Brightness precautions: Hazard Distance (HD)", page 11.
• High Brightness Warning: The projector light source may not be switched on or the shutter must be closed when no projection
lens is installed.
• Based on international requirements, no person is allowed to enter the projected beam within the zone between the projection
lens and the related Hazard Distance (HD). This shall be physically impossible by creating sufficient separation height or by
placing optional barriers. Within the restricted area operator training is considered sufficient. The applicable separation heights
are discussed in "High Brightness precautions: Hazard Distance (HD)", page 11.
• Don't put your hand in front of the beam.
• Before attempting to remove any of the projector's covers, you must turn off the projector and disconnect from the wall outlet.
• When required to switch off the projector, to access parts inside, always disconnect the power cord from the power net.
• The power input at the projector side is considered as the disconnect device. When required to switch off the projector,
to access parts inside, always disconnect the power cord at the projector side. In case the power input at the projector
side is not accessible (e.g. ceiling mount), the socket outlet supplying the projector shall be installed nearby the
projector and be easily accessible, or a readily accessible general disconnect device shall be incorporated in the fixed
wiring.
• Never stack more than 2 UDX projectors in a hanging configuration (truss) and never stack more than 3 UDX projectors in a
base stand configuration (table mount).
• When using the projector in a hanging configuration, always mount 2 safety cables. See installation manual for the correct use
of these cables.
• Do not place this equipment on an unstable cart, stand, or table. The product may fall, causing serious damage to it and
possible injury to the user.
• It is hazardous to operate without lens or shield. Lenses, shields or ultra violet screens shall be changed if they have become
visibly damaged to such an extent that their effectiveness is impaired. For example by cracks or deep scratches.
• Cooling liquid circuit. The projector contains a cooling circuit filled with Mono-ethylene glycol (1,2-ethane diol) and inhibitors
in aqueous solution (34% active). When the cooling circuit leaks, switch off the device and contact qualified service personnel.
The liquid is not for household use. Keep out of reach of children. Harmful by oral intake. Avoid exposure to pregnant women.
Avoid contact with eyes, skin and clothing. Avoid inhale of the noxious fumes.
• Never point or allow light to be directed on people or reflective objects within the HD zone.
• All operators shall have received adequate training and be aware of the potential hazards.
• In case of using an external cooling system position the hoses of the cooling system so that they will not be tripped over, pulled,
or contact hot surfaces.
