Safety
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 15.
• 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 15.
• 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 or shields 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.
To prevent fire hazard
• Do not place flammable or combustible materials near the projector!
• Barco large screen projection products are designed and manufactured to meet the most stringent safety
regulations. This projector radiates heat on its external surfaces and from ventilation ducts during normal
operation, which is both normal and safe. Exposing flammable or combustible materials into close
proximity of this projector could result in the spontaneous ignition of that material, resulting in a fire. For this
reason, it is absolutely necessary to leave an "exclusion zone" around all external surfaces of the projector
whereby no flammable or combustible materials are present. The exclusion zone must be not less than 40
cm (16") for this projector.
• Do not place any object in the projection light path at close distance to the projection lens output. The
concentrated light at the projection lens output may result in damage, fire or burn injuries.
• Ensure that the projector is solidly mounted so that the projection light path cannot be changed by
accident.
• Do not cover the projector or the lens with any material while the projector is in operation. . Mount the
projector in a well ventilated area away from sources of ignition and out of direct sun light. Never expose
the projector to rain or moisture. In the event of fire, use sand, CO
12 R5906112-06 UDX series
or dry powder fire extinguishers. Never
