1. Safety guidelines
Safety Instructions
1. Before returning an instrument to the customer, always make a safety check of the entire instrument, including, but not limited
to, the following items:
a) Be sure that no built-in protective devices are defective and/or have been defeated during servicing. (1) Protective shields
are provided on this chassis to protect both the technician and the customer. Correctly replace all missing protective shields,
including any removed for servicing convenience. (2) When reinstalling the chassis and/or other assembly in the cabinet,
be sure to put back in place all protective devices, including, but not limited to, insulating materials, barriers, covers/shields,
and isolation resistor/capacitor networks. Do not operate this instrument or permit it to be operated without all protective
devices correctly installed and functioning. Servicers who defeat safety features or fail to perform safety checks may be
liable for any resulting damage.
b) Be sure that there are no cabinet openings through which an adult or child might be able to insert their fingers and contact a
hazardous voltage. Such openings include, but are not limited to, (1) excessively wide cabinet ventilation slots, and (2) an
improperly fitted and/or incorrectly secured cover panels.
c) Leakage Current Hot Check. With the instrument completely reassembled, plug the AC line cord directly into a 220 V AC
outlet (Do not use an isolation transformer during this test). Use a leakage current tester or a metering system that complies
with American National Standards Institute (ANSI) C101.0 Leakage Current for Appliances and Underwriters Laboratories
(UL) 1410, (50.7). With the instrument AC switch first in the on position and then in the off position, measure from a known
earth ground (metal waterpipe, conduit, etc.) to all exposed metal parts of the instrument (antennas, handle bracket, metal
cabinet, screwheads, metallic overlays, control shafts, etc.). especially any exposed metal parts that offer an electrical
return path to the chassis. Any current measured must not exceed 3.5 mA. Reverse the instrument power cord plug in the
outlet and repeat test. ANY MEASUREMENTS NOT WITHIN THE LIMITS SPECIFIED HEREIN INDICATE A POTENTIAL
SHOCK HAZARD THAT MUST BE ELIMINATED BEFORE RETURNING THE INSTRUMENT TO THE CUSTOMER OR
BEFORE CONNECTING ACCESSORIES.

d) Ultraviolet Radiation exposure - Warning: This lamp can cause serious skin burn and eye inflammation from shortwave
ultraviolet radiation if not operated in enclosed fixtures. DO NOT operate this lamp in a fixture with a missing or broken lens
cover.
e) Ozone: Operating lamp generates ozone gas which is harmful to the respiratory system. Therefore the lamp should be
operated in adequately ventilated equipment.
2. Read and comply with all caution and safety-related notes on or inside the projector cabinet or on the projector chassis, or on
the picture tube.
3. Design Alteration Warning - Do not alter or add to the mechanical or electrical design of this apparatus. Design alterations and
additions, including, but not limited to, circuit modifications and the addition of items such as auxiliary audio and/or video output
connections, might alter the safety characteristics of this apparatus and create a hazard to the user. Any design alterations
or additions may void the manufacturer’s warranty and may make you, the servicer responsible for personal injury or property
damage resulting therefrom.
4. Lamp explosion Protection Warning – The lamp in this projector operates with a high internal pressure and there is a slight risk
that the lamp may explode, particularly if it is used beyond its rated life. Do not remove, install, or otherwise handle the lamp
in any manner without first putting on shatterproof goggles equipped with side shields. People not so equipped must be kept
safely away while lamps are handled. Keep the lamp away from your body. For continued explosion protection, replace the
lamp only with one of the same type number. Always replace the lamp before the rated life time.
6R59770158 NH-12 20/02/2008

1. Safety guidelines
5. Hot Chassis Warning - This projector chassis has two ground systems: the primary ground system is formed by the negative
voltage of the rectified mains (power) and is only used as a reference in primary circuits; the secondary ground system is
connected to earth ground via the earth conductor in the mains (power) lead. Separation between primary and secondary
circuits is performed by the safety isolation transformers. Components bridging this transformers are also safety components
and must never be defeated or altercated. All user-accessible conductive parts must be connected to earth ground, or are kept
at SELV (Safety Extra Low Voltage).
6. Observe original lead dress. Always inspect in all areas for pinched, out-of-face, or frayed wiring. Do not change spacing
between components, and between components and the printed-circuit board. Check AC power cord for damage. Take extra
care to assure correct lead dress in the following areas:
a) near sharp edges
b) near thermally hot parts - be sure that leads and components do not touch thermally hot parts
c) the AC supply
d) high voltage
7. Components, parts, and/or wiring that appear to have overheated or are otherwise damaged should be replaced with compo-
nents, parts, or wiring that meet original specifications. Additionally, determine the cause of overheating and/or damage and, if
necessary, take corrective action to remove any potential safety hazard.
8. PRODUCT SAFETY NOTICE - Many electrical and mechanical parts have special safety-related characteristics some of which
are often not evident from visual inspection, nor can the protection they give necessarily be obtained by replacing them with
components rated for higher voltage, wattage, etc. Use of a substitute replacement that does not have the same safety charac-
teristics as the recommended replacement part in BARCO service data parts list might create shock, fire, and/or other hazards.
Product Safety is under review continuously and new instructions are issued whenever appropriate. For the latest information,
always consult the appropriate current BARCO service literature.
9. Do not spray chemical on or near this instrument or any of its assemblies.
10. Electrostatically Sensitive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity.
Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated
circuits and some field-effect transistors and semiconductor "chip" components. The following techniques should be used to
help reduce the incidence of component damage caused by static electricity:
a) Immediately before handling any semiconductor-equipped assembly, drain off any electrostatic charge on your body by
touching a known earth ground. Wear a commercially available high impedance discharging wrist strap device.
b) After removing an electrical assembly equipped with ES devices, place the assembly on a static dissipative surface such as
a 3M No 8210 table mat, to prevent electrostatic charge buildup or exposure of the assembly.
c) Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices.
d) Do not remove a replacement ES device from its protective package until immediately before you are ready to install it
(Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminium foil or
comparable conductive material).
e) Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material
to the chassis or circuit assembly into which the device will be installed. CAUTION: Be sure no power is applied to the chassis
or circuit, and observe all other safety precautions.
f) Minimize bodily motions when handling unpacked replacement ES devices (Otherwise harmless motion such as the brush-
ing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to
damage an ES device).
1.2 UV radiation
UV radiation exposure if the rear cover is removed
Warning: When the rear cover of the projector is removed and the lamp is lit, it is not allowed to stay near the projector for over 5
minutes without UV radiation eye and skin protection. The lamp can and will cause serious skin burn and eye inflammation from
shortwave ultraviolet radiation if not operated in enclosed fixtures. DO NOT operate this lamp in a fixture with a missing or broken
lens cover.
UV radiation exposure if the outlet channel is removed
It is prohibited to light the lamp of the projector while the outlet channel is not properly installed, unless proper UV radiation eye
and skin protection is used.
