Servicing Live Equipment - Christie CP2420-Xe Service Manual

• A—Hazard zone. The region of space where the projection light from the projector is above
emission limits for Risk Group 2. The light intensity may cause eye damage after a momentary
or brief exposure (before a person can avert his or her eyes away from the light source). The
light may cause skin burns to occur.
• B—Hazard distance. Operators must control access to the beam within the hazard distance or
install the product preventing potential exposure of the spectators' eyes from being in the
hazard distance.
• C—No access zone. Horizontal clearance of the no access zone must be a minimum of 1.0
meters.
• D—Vertical distance to hazard zone. The hazard zone must be no lower than 2.5 meters (US
installations) or 2.0 meters (global installations) above any surface upon which any persons
are permitted to stand.
If the vertical distance to hazard zone requirement (Zone D) is satisfied, the horizontal
clearance distance (Zone C) is not needed.
• E—Represents the top view of the projector.
• F—Represents the side view of the projector.
For information detailing the hazard distance for each lens, refer to the CP2420-Xe and CP4420-Xe
Installation and Setup Guide (P/N: 020-103555-XX).

Servicing live equipment

Only Christie accredited technicians who are knowledgeable about the hazards associated with
hazardous voltage and high temperatures are authorized to assemble, install, and service Christie
equipment.
To make sure you remain safe when servicing energized (live) Christie equipment:
• Locate the main AC power shut off prior to servicing the equipment. This will allow you to turn
the power off quickly in an emergency.
• Disconnect the projector from the communication and management network so it cannot
receive commands to turn the light source on, open the shutter, and move the lens.
