MOUNTING IN THE CEILING
An improperly mounted projector is a potential danger to
people and equipment. A projector and mount falling down
may cause personal injury and material damage. Such
damage caused by bad workmanship in mounting and
operation may lead to legal action and should be avoided.

Avoid ceiling mounting of the projector in areas of frequent
or probable earth quakes.
or probable earth quakes.
When fixing the mount in the ceiling, be sure to check the ceiling material
and if it will hold the total weight of the mount and the projector. Look for
wood, steel beams or concrete that will secure a good and lasting fixture.
Avoid plaster or other fragile materials that do not have sufficient structural
properties. Follow the detailed instructions supplied with the ceiling mount
for proper mounting and operation.

After having mounted the projector in the ceiling, test if the holding force is
sufficient by adding a load to the mount at least double the weight of the
combined projector and mount. The mount should hold this extra weight
with no sign of fatigue and with no sign of mounting screws loosening.

WIRING
Ceiling mounted projectors require long signal and power wires.
The signals should be wired using high quality coaxial cable. The cables
usually need to be customized. Some vendors have specialized in this field.
Contact your dealer for further detail.

If the signal cables run over a longer distance from the source to the
projector, a line buffer (distribution amplifier) may be needed (available
from third party vendors).

For potential fire reasons, the power wiring should be
separately switched so that the projector can be switched off
completely when not in use. The ON/OFF on the remote
control only suspends operation of the projector without
switching off completely.
