1. Safety
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
fi
rst 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.
5.
Hot Chassis Warning - This projector chassis has two ground systems: the primary ground system is formed by the negative
voltage of the recti
fi
ed 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 these 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 speci
fi
cations. 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,
fi
re, 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
fi
eld-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 suf
fi
cient 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
fl
oor can generate static electricity suf
fi
cient to
damage an ES device).
