Packaging & Contents
Each CD-3000 Series retrofit system is shipped in a custom designed box for protection of the
unit. Keep the box and packaging stored in a safe place. In the unlikely event that the system
needs to be returned to the JSI Factory, the packaging will be required to prevent shipping
damage and maintain warranty.
Each CD-3000 Series system includes all of the hardware required to complete the retrofit.
Installation
CD-3000-AE
• Disconnect (turn off) the power supply to the Strand CD80 ® dimmer rack(s) and rack
processor electronics. Some systems may have their processor electronics powered by an
isolated (separate) feed.
WARNING! Verify all power is disconnected (turned off) before proceeding.
Removal of the Old Processor Housing
• Remove the upper ventilation grill and lower air filter grill from the CD-80 ® rack and set them
aside.
• Inspect the lower portion of the dimmer rack for any wiring, AC line voltage bussing,
conduit, etc. that could prevent the smooth removal of the old processor housing. Take the
appropriate measures to remove any obstructions being careful not to strain or remove any
of the control wiring that terminates on the rear of the existing processor housing.
• Inspect the upper portion of the dimmer rack for any similar obstructions. Pay particular
attention to the upper left side of the dimmer rack. This portion of the rack contains
hardware, circuitry and wiring that must be retained in order to retrofit the rack as designed.
