Safety

R5905304 /03 HDQ 2K406
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 all DLP
projectors. The exclusion zone on the lens side must be at least 5 m. Do not cover the projector or the lens with any material while the
projector is in operation. Keep flammable and combustible materials away from the projector at all times. 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, CO2or dry powder fire extinguishers. Never use water on an electrical fire. Always have service performed on this
projector by authorized Barco service personnel. Always insist on genuine Barco replacement parts. Never use non-Barco
replacement parts as they may degrade the safety of this projector.
•Slots and openings in this equipment are provided for ventilation. To ensure reliable operation of the projector and to protect it from
overheating, these openings must not be blocked or covered. The openings should never be blocked by placing the projector too close
to walls, or other similar surface. This projector should never be placed near or over a radiator or heat register. This projector should
not be placed in a built-in installation or enclosure unless proper ventilation is provided.
•Projection rooms must be well ventilated or cooled in order to avoid build up of heat.
•Let the projector cool completely before storing. Remove cord from the projector when storing.
•Heat sensitive materials should not be placed in the path of the exhausted air or on the lamp house.
•When the projector is used in portrait mode, the air outlet is positioned towards the floor. That's why the floor covering can become
very hot and must be resistant to a temperature of 90 °C (194 °F).
To prevent projector damage
•This projector has been designed for use with a specific lamp (house) type. See installation instructions for its correct type.
•The air filters of the projector must be cleaned or replaced on a regular basis (a "clean" booth would be monthly-minimum). Neglecting
this could result in disrupting the air flow inside the projector, causing overheating. Overheating may lead to the projector shutting
down during operation.
•The projector must always be installed in a manner which ensures free flow of air into its air inlets and unimpeded evacuation of the
hot air from its cooling system.
•In order to ensure that correct airflow is maintained, and that the projector complies with Electromagnetic Compatibility (EMC) and
safety requirements, it should always be operated with all of it's covers in place.
•Slots and openings in the cabinet are provided for ventilation. To ensure reliable operation of the product and to protect it from
overheating, these openings must not be blocked or covered. The openings should never be blocked by placing the product on a bed,
sofa, rug, or other similar surface. This product should never be placed near or over a radiator or heat register. The device should not
be placed in a built-in installation or enclosure unless proper ventilation is provided.
•Ensure that nothing can be spilled on, or dropped inside the projector. If this does happen, switch off and remove all power from the
projector. Do not operate the projector again until it has been checked by qualified service personnel.
•Do not block the projector cooling fans or free air movement around the projector. Loose papers or other objects may not be nearer to
the projector than 10 cm (4") on any side.
•Do not use this equipment near water.
•Proper operation of the cooling circuit can only be guaranteed in the allowed projector positions. It is not allowed to use the projector in
another position. See installation instructions for correct installation.
•Special care for Laser Beams: Special care should be used when DLP projectors are used in the same room as high power laser
equipment. Direct or indirect hitting of a laser beam on to the lens can severely damage the Digital Mirror DevicesTM in which case
there is a loss of warranty.
•Never place the projector in direct sun light. Sun light on the lens can severely damage the Digital Mirror DevicesTM in which case
there is a loss of warranty.
•Save the original shipping carton and packing material. They will come in handy if you ever have to ship your equipment. For
maximum protection, repack your set as it was originally packed at the factory.
•Disconnect the power to the projector mains terminals and unplug the power cord at UPS INLET before cleaning. Do not use liquid
cleaners or aerosol cleaners. Use a damp cloth for cleaning. Never use strong solvents, such as thinner or benzine, or abrasive
cleaners, since these will damage the cabinet. Stubborn stains may be removed with a cloth lightly dampened with mild detergent
solution.
•To ensure the highest optical performance and resolution, the projection lenses are specially treated with an anti-reflective coating,
therefore, avoid touching the lens. To remove dust on the lens, use a soft dry cloth. Do not use a damp cloth, detergent solution, or
thinner.
•Rated maximum ambient temperature, ta= 35 °C (95 °F).
•The lamp house shall be replaced if it has become damaged or thermally deformed.
On servicing
•Do not attempt to service this product yourself, as opening or removing covers may expose you to dangerous voltage potentials and
risk of electric shock.

•Attempts to alter the factory-set internal controls or to change other control settings not specially discussed in this manual can lead to
permanent damage to the projector and cancellation of the warranty.
•Remove all power from the projector and refer servicing to qualified service technicians under the following conditions:
- When the power cord or plug is damaged or frayed.
- If liquid has been spilled into the equipment.
- If the product has been exposed to rain or water.
- If the product does not operate normally when the operating instructions are followed. Adjust only those controls that are covered
by the operating instructions since improper adjustment of the other controls may result in damage and will often require extensive
work by a qualified technician to restore the product to normal operation.
- If the product has been dropped or the cabinet has been damaged.
Safety

7R5905304 /03 HDQ 2K40
- If the product exhibits a distinct change in performance, indicating a need for service.
•Replacement parts: When replacement parts are required, be sure the service technician has used original Barco replacement parts
or authorized replacement parts which have the same characteristics as the Barco original part. Unauthorized substitutions may result
in degraded performance and reliability, fire, electric shock or other hazards. Unauthorized substitutions may void warranty.
•Safety check: Upon completion of any service or repairs to this projector, ask the service technician to perform safety checks to
determine that the product is in proper operating condition.
•Possible explosion hazard: Always keep in mind the caution below:
CAUTION: Xenon compact arc lamps are highly pressurized. When ignited, the normal operating temperature of the bulb
increases the pressure to a level at which the bulb may explode if not handled in strict accordance to the manufacturer's
instructions. The bulb is stable at room temperature, but may still explode if dropped or otherwise mishandled. Whenever the
lamp house, containing a xenon lamp, has to be dismantled or whenever the protective container or cloth has to be removed
from the xenon lamp, authorized protective clothing MUST be worn!
Authorized protective clothing for xenon lamp handling
WARNING: Always wear face protection (full face shield) when handling xenon lamps.
WARNING: Always wear protective clothing (welder's jacket) when handling xenon lamps.
WARNING: Always wear clean leather gloves with wrist protectors when handling xenon lamps.
To prevent battery explosion
•Danger of explosion if battery is incorrectly installed.
•Replace only with the same or equivalent type recommended by the manufacturer.
•For disposal of used batteries, always consult federal, state, local and provincial hazardous waste disposal rules and regulations to
ensure proper disposal.
Safety Data Sheets for Hazardous Chemicals
For safe handling information on chemical products, consult the Safety Data Sheet (SDS). SDSs are available upon request via
[email protected].
1.3 High Brightness precautions: Hazard Distance
HD
Hazard Distance (HD) is the distance measured from the projection lens at which the intensity or the energy per surface unit
becomes lower than the applicable exposure limit on the cornea or on the skin. The light beam is considered (to be) unsafe
for exposure if the distance from a person to the light source is less than the HD.
Restriction Zone (RZ) based on the HD
The HD depends on the amount of lumens produced by the projector and the type of lens installed. See chapter “HD in function of
modifying optics”, page 10.
To protect untrained end users (as cinema visitors, spectators) the installation shall comply with the following installation requirements:
Operators shall control access to the beam within the hazard distance or install the product at the height that will prevent spectators' eyes
from being in the hazard distance. Radiation levels in excess of the limits will not be permitted at any point less than 2.0 meter (SH) above
any surface upon which persons other than operators, performers, or employees are permitted to stand or less than 1.0 meter (SW)
lateral separation from any place where such persons are permitted to be. In environments where unrestrained behavior is reasonably
foreseeable, the minimum separation height should be greater than or equal to 3.0 meter to prevent potential exposure, for example by an
individual sitting on another individual's shoulders, within the HD.
These values are minimum values and are based on the guidance provided in IEC 62471-5:2015 section 6.6.3.5.
The installer and user must understand the risk and apply protective measures based upon the hazard distance as indicated on the label
and in the user information. Installation method, separation height, barriers, detection system or other applicable control measure shall
prevent hazardous eye access to the radiation within the hazard distance.
For example, projectors that have a HD greater than 1 m and emit light into an uncontrolled area where persons may be present should
be positioned in accordance with “the fixed projector installation”parameters, resulting in a HD that does not extend into the audience
area unless the beam is at least 2.0 meter above the floor level. In environments where unrestrained behavior is reasonably foreseeable,
the minimum separation height should be greater than or equal to 3.0 meter to prevent potential exposure, for example by an individual
sitting on another individual's shoulders, within the HD. Sufficiently large separation height may be achieved by mounting the image
projector on the ceiling or through the use of physical barriers.

Based on national 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 barriers. The
minimum separation height takes into account the surface upon which persons other than operator, performers or employees are
permitted to stand.
On Image 1–3 a typical setup is displayed. It must be verified if these minimum requirements are met. If required a restricted zone (RZ) in
the theater must be established. This can be done by using physical barrier, like a red rope as illustrated in Image 1–3.

1.4 HD for fully enclosed projection systems
HD
Hazard Distance (HD) is the distance measured from the projection lens at which the intensity or the energy per surface unit
becomes lower than the applicable exposure limit on the cornea or on the skin. The light beam is considered (to be) unsafe
for exposure if the distance from a person to the light source is less than the HD.
Restriction Zone (RZ) based on the HD
The projector is also suitable for rear projection applications; projecting a beam onto a defuse coated projection screen. As displayed in
Image 1–4 two areas should be considered: the restricted enclosed projection area (RA) and the observation area (TH).

SW Separation Width. Must be minimum 1 meter.
For this type of setup 3 different HD shall be considered:
•HD as discussed in “High Brightness precautions: Hazard Distance”, page 7, relevant for intrabeam exposure.
•HDreflection : the distance that has to be kept restrictive related to the reflected light from the rear projection screen.
•HDdiffuse : the relevant distance to be considered while observing the diffuse surface of the rear projection screen.
As described in “High Brightness precautions: Hazard Distance”, page 7, it is mandatory to create a restricted zone within the beam areas
closer than any HD. In the enclosed projection area the combination of two restricted zones are relevant: The restricted zone of the
projected beam toward the screen; taking into account 1 meter Separation Width (SW) from the beam onward. Combined with the
restricted zone related to the rear reflection from the screen (HDreflection); also taking into account a 1 meter lateral separation.
The HDreflection distance equals 25% of the difference between the determined HD distance and the projection distance to the rear
projection screen. To determine the HD distance for the used lens and projector model see chapter “HD in function of modifying optics”,
page 10.
HDreflection = 25% (HD – PD)
The light emitted from the screen within the observation shall never exceed the RG2 exposure limit, determined at 10 cm. The HDdiffuse
can be neglected if the measured light at the screen surface is below 5000 cd/m² or 15000 LUX.
