or involuntary movement. Proper securing of the projector is the responsibility of the installer and user. The
Projector are heavy, and can cause severe damage and injuries if falling.
General guidelines
Proper positioning of the projector lessens the overall picture setup time, and ensures a better image with fewer artifacts.
Focus and sharpness of the image can be adversely affected if the lens axis is not fully perpendicular to the
projection surface.
Using extended cable lengths may result in reduced image quality as well as loss of control information such
as EDID (Extended Display Information Data).
The following guidelines can help you determine the best physical location for the projector.
• Only install the projector on a sturdy flat surface, or in an approved rigging frame.
• Do not install the projector in a thoroughfare or other area where it is at risk of being pushed or jostled.
• Allow sufficient free space around the projector for ventilation and exhaust, as described in section "Installation conditions",
page 25.
• Use the throw ratio of the installed lens as a guideline for the projector's physical distance from the screen.
• Wherever possible, the projector lens surface should be positioned so that it is perfectly perpendicular to the center of the
screen.
Use the projector offset (lens shift), rather than physical angling, to correct any off-center positioning.
• Minimize the source cable length as much as possible.
In general HDBaseT and 3G-SDI are long-haul interfaces and suitable for bespoke installations using relatively long cables.
DP, HDMI and DVI are short-haul interfaces using pre-assembled cables with limited cable lengths.
• Limit the use of power cable extensions wherever possible. Where physical limitations necessitate their use, make sure that
the extension cord has adequate surge protection and meets all electrical requirements of the connection.
• Keep the projector away from equipment that emits electromagnetic energy for example, motors, transformers and elevators.

Mounting the projector

Mounting safety
When mounting a projector in a rig, always use an interface plate (between the projector and the mount) that has provision for a
safety wire or another safety mechanism, to ensure that the projector does not fall down should the interface plate come loose from
the mount.
Always screw the interface plate securely to the projector body while the projector is on the ground (i.e. cannot fall down). Then
attach proper safety wire between the interface plate and the rig before mounting the projector in the rig
Where possible, the projector lens must be positioned exactly perpendicular to the center of the screen. Use
the projector offset (lens shift), rather than physical angling, to correct any off-center positioning.
