the cable from rubbing against the projector knockout plate and becoming damaged.
When connecting the projector to AC power, follow all electrical codes for your location. In addition, follow
these recommendations:
• A 30-32A double pole, UL listed wall circuit breaker is required. It must be part of the building installation
and easily accessible.
• Use 10AWG or 8AWG wiring. The distance between the wall circuit breaker and the projector must not
exceed 20 meters using 10AWG cables or 30 meters using 8AWG cables.
• For North American installations, use at least 10AWG copper wires for the connection of the main AC sup-
ply to the projector's ground lug.
• Copper or aluminum are acceptable as conductor wiring material to the terminal block.
1. On the bottom of the projector in the front right corner, loosen the two screws and slide the plate forward to
expose the terminal block.
2. Remove the knockout plate located in the bottom right corner of the front bezel. The AC supply is routed
to the terminal block through an appropriate strain relief mounted on this knockout plate.
3. Connect the AC power source to the terminal block, beginning with the ground lead first. Use an
appropriately sized strain relief connector with the knockout plate provided to ensure adequate
environmental sealing and to prevent the cables from wear and accidentally being torn out. NOTES: 1)
The terminal block accommodates up to an 8 AWG wire. 2) If desired, a 90° strain relief connector can be
used to route the power cable in a downward direction.
