Connecting Power
1. Bring AC power next to the electronics module. Connect the power to the receptacle located on the rear panel. The voltage can be
115 VAC (90–132 VAC) or 230 VAC (200–254 VAC). Refer to Figure 10.

2. The AC power can be looped through to the next PMCD750 unit, resulting in fewer main outlet sockets needed for operation. The total
number of units in one power loop cannot exceed four (115 VAC) or eight (230 VAC) units.
3. Turn on the power switch for each display. When AC power is applied, there are a few seconds of apparent inactivity in which the
electronics module begins start up and initialization. Next, if the optical engine is warm, the intake and lamp fans start. Because the
service life of the lamp can be significantly shortened if turned on when hot, the lamp cannot be turned on during this time. The lamp fan
runs for approximately one minute to ensure the lamp is cool. If the temperature sensor on the optical engine determines that the lamp is
sufficiently cool at power up, this cool-down period is skipped.
NOTES:
The AC switch on each PMCD750 unit controls that display only. Turning off the switch on any display does not cut the AC power to the other
displays. The switch is lit when it is ON and there is AC power to the PMCD750 unit.
The AC input is fused with a 10 A fuse. If the fuse in any PMCD750 unit blows, all displays downstream from this one will go off.
SHUT-DOWN SEQUENCE
The lamp fan runs continuously while the lamp is on. When the lamp is turned off, the intake fan shuts off 15 seconds later, while the lamp fan
continues to run for an additional 5 minutes to cool the lamp. If the display must be disconnected from power, do the following:
1. Press OFF on the remote control.
2. Wait for the lamp fan to stop running.
3. Press the AC power switch on the rear of the display to turn off the power.
4. Remove the power cord from the AC in receptacle.
WARNING:
Do not exceed the recommended number of PMCD750 units linked in series for AC power or the current draw will be too great.
WARNING:
Turning off the PMCD750 display by turning off the power switch does not allow the lamp to cool down properly. Turning the
display off by this method may significantly shorten the service life of the lamp.
