1. Safety guidelines

Safety Instructions

1. Before returning an instrument to the customer, always ma ke 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. Co rrectly replace all m issing protective shields,

including any rem oved for servicing convenience. (2) W hen reinstalling the chassis and/or o ther assem b ly in the cabinet,

be sur e to put b ack in p lace 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 perm it 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 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) excessively wide cab inet v

entilation slots, and (2) an

improperly ﬁtted and/or incorrectly secured cover panels.

c) Leakage Current Hot Check. With the instrument completely reassembled, plug the A C line c ord directly into a 220 V A C

outlet (Do not use an isolation transformer during this test). Use a leaka ge current tester or a m etering system that com plies

with American National Standards Institute (ANSI) C101.0 Leakage Current for Applianc es and Underwriters Laboratories

(UL) 1410, (50.7). With the instrum ent AC switch ﬁrst in t he on position and then in the off position, measure from a known

earth ground (m etal waterpipe, conduit, etc.) to all exposed metal pa rts of the instrument (antennas, handle bracket, metal

cabinet, screwheads, metallic ov erlays, control shafts, etc.). especially any ex posed m etal parts that offer an electrical

return path to the c hassis. A ny current measu red must not exceed 3 .5 mA. Reverse the instrument power c ord plug in the

outlet and repeat test. ANY M EASUR EM ENTS NOT WITHIN T HE LIMITS SPECIFIED HEREIN INDICAT E A POTENTIAL

SHOCK HAZARD THAT M US T BE ELIMINATED BEFORE R ETURNING THE INSTRUMENT TO THE CUSTOMER OR

BEFORE CON NECTING ACCES SORIES.

d) Ultraviolet Radiation exposure - Warning: Th is lamp can cause serious skin burn and eye inﬂam m ation from shortwave

ultraviolet radiation if n

ot operated in enclosed ﬁxtures. DO NO T operate this lamp in a ﬁxture w ith 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 comply w ith all caution and safety-related notes on or inside the projector cabinet or on the projector chas sis, or on

the picture tube.

3. Design Alteration Warning - Do not alter or add to the m echanical or electrical design of this apparatus. D esign alterations and

additions, including, but n ot limited to, circuit modiﬁcations and the addition of items s uch as auxiliary audio and/or video o utput

connections, might alter the safety characteristics of this apparatus a n d create a hazard to the user. Any design alterations

or additions m ay void the manufacturer ’s warranty and may make yo u, the servicer responsible for personal injury or property

damage resulting therefrom.

4. Lam p explosion Protection Warning – The lamp in this pr ojector 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 rem ove, install, or otherwise handle t he lamp

in any manner without ﬁrst putting on shatterproof goggles equipped with side shields. People not s o equipped m ust be kept

safely away while lamps are handled. K eep the lamp away from you r body. For continued explosion pr otection, r eplace the

lamp only with o

ne of the same type number. A lways replace the lamp before the rated life time.

1. Safety guidelines

5. Hot Chassis Warning - This projector chassis has two g round systems: the primary ground system is formed by the negative

voltage o f the rectiﬁed mains (power) and is only used as a reference in primary circuits; the secondary ground sy stem is

connected to earth gr ound 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 mu st never be defeated or altercated. All user-accessible co nductive parts must be connected to earth gr ound, or are kept

at SELV (Safety Ex tra Low Voltage).

6. O bserve original lead dress. Always inspect in all areas for pinche d, out-of-face, or frayed wiring. Do not change spa cing

between compone nts, and between components and the printed-circuit b oard. Check AC pow er 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 A C supply

d) high v oltage

7. Com ponents, parts, and/or wiring that appear to have overheated or are otherwise damaged should be replaced with compo-

nents, parts, or wiring that me et original speciﬁcations. Additionally, determine the cause of overheating and/or damage and, if

necessary, take corrective ac tion to remove any potential safety hazard.

8. PR OD UCT SAFET Y NO T ICE - Many electrical and mechanical parts have special safety-related c haracteristics s ome of w hich

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 s ame safety charac-

teristics as the recom m ended replacement part in BARCO service data parts list might create s hock , ﬁre, and/or other hazards.

Product Safety is under review continuously and new instructions are issued whenever approp

riate. For the latest information,

always consult the appropriate current BA RCO service literature.

9. Do not spray che mical on or near this instrument or any of its assemblies.

10. Electrostatically S ensitive (ES) D evices Some semiconductor (solid state) devices c an be damaged easily by static elec tricity.

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 reduce t he incidence of component damage caused by static elec tricity:

a) Immediately before handling any semiconductor-equipped ass embly, drain off any electrostatic charge on your body by

touching a known earth gr ound. Wear a comm ercially available h igh impedance dis charging wris t strap device.

b) After removing an electrical assembly equipped with ES devices , pla

ce the assembly on a static dis sipative s urface such as

a 3M No 8210 table m at, 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 dev ices.

d) Do not remove a replacement E S device from its protective package until immediately before you are ready to install it

(Most replacem ent ES devices are packaged with leads electrically shorted together by conductive foam, a luminium 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 device w ill be installed. CA UT ION: B e sure n o power is applied to the chassis

or circuit, and observe all other safety precautions.

f) Minimize bo dily motions when handling unpacked repl

acement ES devices (Otherwise harmless motion such as the brush-

ing together of your clothes f abric or 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 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 w ill cause serious s kin burn a nd eye inﬂammation from

shortwave ultraviolet r adiation if not operated in enclosed ﬁxtures. DO NOT 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 ou tlet c hannel is not properly installed, unles s proper UV radiation eye

and skin protection is used.
