9. Connect the power cord and other cables to the projector
Connect any necessary cables such as the power cord, computer cable, HDMI cable, and USB cable to
the projector.
If you are using both USB Display and interactive connectivity, make sure you label the

If you are planning to run the cables inside the wall, make sure you follow all local electrical codes. If

obstructing the image. An optional cable management system is available from Epson
(part # ELPCK01).
