Precautions with regard to safety
6
Read these operating instructions thoroughly and check all necessary safety precautions
when setting up the projector in order to avoid accidents.
WARNING
Setting-up
Installation should only be carried out by a qualified technician.
• In order to maintain full safety and precision during installation, such work should only be carried out by a
qualified technician.
At least three people are needed to set up the projector.
• This projector is manufactured with high precision and is very heavy. If only one person attempts to install or
move the projector by himself, the projector may be damaged or injury may result. Always make sure that at least
three people are available to transport and install the projector.
Check the strength of the installation location.
• This projector weighs 100 o(220 lb). When coupled with the ceiling mount bracket (sold separately), the total
weight becomes 129 o(283.8 lb). If the installation location is not strong enough to bear the weight, carry out any
reinforcement measures that may be necessary to ensure that the installation location will be free of any
problems regarding strength and safety.
Avoid installing the projector in any of the following places:
• Places which are subject to vibration or shocks • • • • •Vibration and shocks may cause malfunctions or accidents.
• Next to sprinklers or sensors • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • Heat produced by the projector may cause sensors to
operate incorrectly or sprinkler systems to be activated, which
could cause problems.
• Near high-voltage power lines or motors • • • • • • • • • • • • • • • Such power sources may cause interference.
• Places with adverse ambient conditions • • • • • • • • • • • • • • • Avoid places which are extremely dusty, where oil fumes or
vapor are present, and where the ambient temperature is
outside the range of 0 °C – 40 °C(32 °F – 104 °F) or the
ambient humidity is outside the range of 10 % – 80 %. If the
projector is installed in such places, operating problems, fire
or electric shocks may result.
Do not connect any power supply to the projector other than one with power supply
voltage indicated (single-phase, 3-wire, 200 V–240 VAC)
• If the wrong power supply is connected, the projector may malfunction, and fire or electric shocks may result.
A special ceiling mount bracket (sold separately) is required for ceiling installation.
• If suspending the projector from a ceiling, you must purchase and use the special ceiling mount bracket (ET-
PKD95).
Use commercially-available screens.
• Select a screen which matches the projection method to be used and the place of use.
Keep external light away from the screen.
• Do not allow light from any sources other than the projector fall on the screen. If the screen is illuminated by such
external light, the projected image will lose its high contrast and will not be so easy to see.
Allow enough space around the projector for maintenance to be carried out.
• Leave at least 80 cm / 2.6 feet of free space on all sides of the projector to allow enough room for adjustments
and maintenance to be carried out.
Always connect to a secure earth.
• Connect an earth wire to the earthing screw marked with next to the
MAIN POWER switch. Then connect this earth wire to a secure earthing
terminal somewhere inside the room.
If the projector is used without the earth wire connected, electric shocks may
result.
