Power Supply

The power supply fastens to the chassis. It converts 100-240 VAC supply voltage to various low voltage
DC levels required internally by the projector. The power supply interfaces with the ballast through the
lamp control cable to control lamp strike and operation, and through the power supply/ballast cable to
provide DC power. The power supply also interfaces with the controller ECA through the power
supply/controller ECA cable to provide DC power and exchange control signals.

2 Unplug the safety switch cable from J3 on the power supply. Then unplug the power
supply/controller ECA cable from P1, the ballast/power supply cable from J1 and the lamp control
cable from J4 on the power supply. Squeeze the latches on the power supply/controller ECA
cable and the power supply/ballast cable connectors to release them.
