Connecting an External
Power Supply/Ballast to
the Projection Head
The SC-1 is optionally available in a split-body configuration in which the power
supply/ballast is separate from the projection head. This configuration is useful for
installations where the projection area is too small to accommodate a single-body SC-1,
or the 220-VAC source cannot be conveniently accessed from the projection area.
The external power supply/ballast connects to the SC-1 in two places: the lamp igniter
connection panel and the AC/lamp control input panel, as shown in
Figure 3-20.
Figure 3-20. External Power Supply/Ballast Connection
If the power supply/ballast is internal to your SC-1 (as shown in Figure
2-1), continue with the next step, Connecting to AC Power.
