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 p rotective devices are defective and/or have been defeated during servicing. (1) P rotective shields
are pro vided on this chassis to protect both the technician and the customer. Correctly replace all m issing protective shields,
including any rem oved for servicing convenience. (2) When reinstalling the chassis and/or o ther assembly in the cabinet,
be sur e 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 ope rate this instrument or permit it to be operated without all protective
devices correctly installed and functioning. Servicers who de feat safety features or fail to perform safety checks may be
liable for any resulting da mage.
b) Be su re that there are no cabinet openings through which an adult or child m ight be able to insert their fingers and contact a
hazardous voltage. Such openings include, but are not limited to, (1) exc essively w ide cabinet v
entilation slots, and (2) an
improperly fitted and/or incorrectly se cured c over panels.
c) Leakage C urrent Hot Check. With the instrument completely reassembled, plug the AC line cord directly into a 220 V A C
outlet (Do not use an isolation transformer during this test). Use a leakage current tester or a metering system that complies
with Am erican National Standards Institute (ANSI) C101.0 Leakage Current for Applianc es and Underwriters Laboratories
(UL) 1410, (50.7). W ith 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 m A. Reverse the instrument power cord plug in the
outlet and repeat test. ANY MEASUR EM ENTS NOT WITHIN THE LIMITS SPE CIFIED H EREIN INDICATE A POTENT IAL
SHOCK HAZARD THAT MUST BE ELIMINATED BEFORE RETURNING THE INSTRUM ENT TO THE CUSTOMER OR
BEFORE CON NECTING ACCES SORIES.

d) Ultraviolet Radiation exposure - Warning: This lamp can cause serious skin burn and eye inflammation from shortwave
ultraviolet radiation if n
ot operated in enc losed fixtures. D O NOT operate this lamp in a fixture with a missing or broken lens
cover.
e) Ozone: Operating lamp ge nerates ozone gas which is harmful to the respiratory system. Therefore the lamp should be
operated in adequately ventilated equipm ent.
2. Read and com ply 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 - D o not alter or add to the m echanical or electrical des ign of this apparatus. Design a lterations and
additions, including, but n ot limited to, c ircuit mod ifications and the addition of items such as auxiliary audio an d/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 v oid the manufacturer ’s warranty and may m ake you, the servicer respon sible for persona l injury or pr operty
damage resulting therefrom.
4. Lam p explosion Protection Warning – The lamp in this projector operates with a high internal pressure and there is a slight risk
that the lamp may e
xplode, particularly if it is used beyond its rated life. Do not remove, install, or otherwise handle the lamp
in any m anner witho ut first putting on shatterproof goggles equipped with side shields. People not so equipped m ust be kept
safely away while lamps are handled. Keep the lamp away from your body. For c ontinued explosion pr otection, r eplace the
lamp only with o
ne of the same type n umber. Always replac e the lamp before the rated life time.

1. Safety guidelines
5. Hot Chassis Warning - This projector chassis has two ground systems: the primary ground system is formed by the negative
voltage o f the rectified m ains (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 s econdary
circuits is pe rformed by the safety isolation transformers. Components bridging this transformers are also safety components
and mu st never be defeated or altercated. A ll user-accessible conductive parts mus t be connected to earth ground, or are kept
at SELV (Safety Ex tra Low Voltage).
6. O bserve original lead dress. Always inspect in all areas for pinched, out-of-face, or frayed wiring. Do not change spacing
between compone nts, and between com ponents and the printed-circuit board. Check AC power c ord 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 c omponents do not touch thermally hot parts
c) the AC supply
d) high v oltage
7. Com ponents, parts, and/or wiring that appear to have overheated or are otherwise damaged s hould be replaced with comp o-
nents, parts, or wiring that meet original specifications. A dditionally, determine the cause of overheating and/or damage and, if
necessary, take corrective action to remove any potential safety hazard.
8. PR OD UCT SAFETY NOTICE - Many electrical and me chanical parts have special safety-related c haracteristics s ome of which
are often not evident from visual inspection, nor c an the protection they give necessarily be obtain
ed by replacing them with
components rated for higher voltage, wattage, etc. Use of a substitute replacement that doe s not have the same safety charac-
teristics as the recomm ended replacement part in BARCO service data parts list might create shock , fire, and/or other haz ards.
Product Safety is under review continuously and new ins tructions are issued whenever a pprop
riate. For the latest information,
always c onsult the appropriate current BARCO service literature.
9. Do not spray chemical on or near this instrument or any of its ass emblies.
10. Electrostatically Sensitive (ES) Devices Some semiconductor (solid state) devic es can be damaged eas ily b y static electricity.
Such compo nents commonly are c alled E lectrostatically Sens itive (ES) D evices. E xam ples of typical ES devices ar e integrated
circuits and some field-effect transistors and sem iconductor "chip" c omponen ts. The following techniques should be used to
help re duce the incidence of c omponent damage caused by static electricity:
a) Immediately before handling any se miconductor-equipped ass embly, drain off any electrostatic charge on your body by
touching a known earth gr ound. Wear a commerc ially available high im pedance dis charging wrist strap dev ice.
b) After removing an elec trical assembly equipped with ES devices, pla
ce the assembly on a static dissipative surface such as
a 3M No 8210 table mat, to prevent electrostatic charge buildup o r ex posure of the assembly.
c) Do not use freon-propelled chemicals. These c an generate electrical charges sufficient to damage ES devices.
d) Do not rem ove a replacement E S device from its protective package until immediately before you are ready to install it
(Most replacement ES dev ices are packaged with leads electric ally shorted together by conductive foam, aluminium foil or
comparable condu ctive 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 dev ice w ill be installed. CA UTION: B e s ure n o power is applied to the chassis
or circuit, and observe all other safety precautions.
f) Minimize bo dily motions when h andling unpacked repl
acement ES devices (Otherwise harm less motion such as the brush-
ing together of your clothes fabric o r the lifting of your foot from a carpeted floor can generate static electricity sufficient to
damage an E S device).
1.2 UV radiation
UV radiation exposure if the rear cover is removed
Warning: W hen the rear cover of t he projector is rem oved and the lamp is lit, it is not allowed to s tay near the projector for over 5
minutes without UV rad iation eye and skin protection. Th e lamp ca n and w ill cause serious skin burn and eye inflamm ation from
shortwave ultraviolet radiation if not operated in enclosed fixtures. DO NO T operate this lamp in a fixture with a missing or broken
lens cove r.
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, unles s proper UV radiation eye
and skin protection is used.
