Projector Installation
This appendix provides guidelines on installing the projector in a 
permanent location, such as a theater or conference room.
Installation Guidelines
The projector can be installed for four different viewing setups: front 
projection, ceiling projection, rear projection onto a semi-transparent 
screen, or rear/ceiling projection, as shown: 
To project from overhead, you’ll need the optional ceiling mounting 
hardware (see page 15). You’ll also need to select the appropriate 
Projection setting in the projector’s Extended menu to flip the image 
upside-down (see page 126).
Front projectionRear projection
Rear/ceiling projectionCeiling projection 
						

							164Projector InstallationIf you’re mounting the projector on the ceiling and you place it above 
screen level, you’ll have to tilt the projector down to position the 
image on the screen. This causes the image to lose its square shape. 
You can correct the image using the projector’s 
Quick Corner and/or 
Keystone functions, as described on page 58.
Security Features
The projector includes security features to prevent its theft when 
installed or used in public locations: 
■Security cable attachment. You can attach a commercially 
available security cable as shown below to secure the projector to a 
table or ceiling mount.
■Kensington security slot. The security slot (located above the 
power inlet) is compatible with the MicroSaver security systems 
manufactured by Kensington. You can purchase this lock from 
Epson (see page 15).

In addition, the projector includes several menu-operated security 
features. See page 121.
