1. Safety
4. Lamp 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 explode, particularly if it is used beyond its rated life. Do not remove, install, or otherwise handle the lamp
in any m anner without first putting on shatterproof goggles eq uipped with s ide sh ields. Pe ople not so equipped m ust be kept
safely away while lamps are handled. Keep the lamp away from yo u r body. For c ontinued explosion protection, r eplace the
lamp only with one of the same type number. Always replace the lamp before the rated life time.
5. Hot Chassis Warning - This projector chassis has two g round s ystem s: the primary ground system is formed by the negative
voltage of the rectified mains (power) and is only used a s a reference in primary circuits; the secondary ground system is
connected to earth gr ound via the earth conductor in the mains (p ower) lead. Separation between primary and s econdary
circuits is performed by the safety isolation transformers. Components bridging these transformers are also safety components
and mu st never be defeated or altercated. A ll us er-accessible conductive parts mus t be connected to earth ground, or are kept
at S ELV (Safety Extra Low Voltage).
6. Observe original lead dress. A lways inspect in all areas for pinched, out-of-face, or frayed wiring. Do not change spacing
between c ompone nts, and between components and the printed-circuit board. 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 an d c omponents 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 w ith compo-
nents, parts, or wiring that meet original spe cifications. Additionally, de termine the cause of overheating and/or damage and, if
necessary, take corrective action to rem ove any p otential safety hazard.
8. PRODUCT SAFE TY NOTICE - Many electrical and mechanical parts have special s afety-related characteristics some of w hich
are often not evident from visual inspection, nor can the pr otection they give necessarily be obtained 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 recommended replacement part in BAR CO service data par ts list might create s hock, fire, and/or other hazards.
Product Safety is under review continuously and new instructions are issued whenever a ppropriate. For the latest information,
always consult the appropriate current BARCO service literature.
9. Do not spray che mical o n or near this instrument or any of its assemblies.
10. Electrostatically S ensitive (ES) Devices Som e sem iconductor (solid state) devices can be damaged easily by static elec tricity.
Such compo nents commonly are called E lectrostatically Sens itive (ES) D evices. Examples of typical E S devices ar e integrated
circuits and some field-effect transistors and sem iconductor "chip" componen ts. The following techniques should be used to
help reduce the inc idence of component damage caused by static electricity:
a) Immediately before handling any semiconductor-equipped asse
mbly, drain off any electrostatic charge on your body by
touching a known earth gr ound. Wear a commerc ially available high im pedance discharging wrist strap device.
b) After removing an e lectrical ass embly equipped with ES devices, place the assembly on a static dissipative surface such as
a 3M No 8210 table m at, to prevent electrostatic charge buildup o r 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 im mediately before you are ready to install it
(Most replacement ES devices are p a ckaged with leads electrically shorted together by c onductive 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 as semb ly into which t he d
evice will be installed. CAUTION: Be s ure n o power is applied to the chassis
or circuit, and observe all other safety precautions.
f) Minimize bodily motions w hen h andling unpacked replac ement ES devices (Otherwise harmless motion suc h as the brush-
ing together of your clothes fabric o r the lifting of your foot from a c arpeted floor can generate static electricity sufficient to
damage an ES device).
