AC/Power Precautions
Installation of this projector requires that an electrician hard-wire (permanent-wire) a single-phase feed from
the projector to the AC supply at the building site. Operate the projector at the specified voltage.
• This product may be connected with multiple power sources. Before opening, removal all
hazardous voltages by disconnecting all power sources.
• DO NOT attempt operation if the AC supply is not within the specified voltage range.
• This product does not include a built in AC breaker. A 30-32A double pole, UL listed wall cir-
cuit breaker is required. It must be part of the building installation and easily accessible.
• DO NOT use a wall breaker greater than 32A. This could result in severe damage to the pro-
jector in the event of a failure.
• Protection from over-currents, short circuits and earth faults must be part of the building
installation. A disconnect device (double pole switch or circuit breaker with minimum 3 mm
contact gap) must be readily accessible within the projection room.
• Disconnect projector from AC before opening any enclosure.
• DO NOT allow anything to rest on the power cord. Locate the projector where the cord can-
not be abused by persons walking on it or objects rolling over it. Never operate the projec-
tor if the power cable appears damaged in any way.
• DO NOT overload power outlets and extension cords as this can result in fire or shock haz-
ards.
• Note that only Christie authorized service technicians are permitted to open any enclosure
on the product and only if the AC has been fully disconnected from the product.
