Configuring the Ballast
For Incoming AC
Connect to Projector
'
AC power levels vary from region to region throughout the world, with 400 VAC
common in some countries (such as those in Europe and Asia), and 200 AC common
elsewhere (such as in North America and Japan). To accommodate both possibilities,
this ballast includes an internal Input Power Range Switch for toggling to the level of
AC available at the installation site, i.e. either 200 or 400 VAC. The line cord plug
must also match.
From the factory, the ballast's switch and line cord are both set for 200 VAC use.
Used/rented ballasts shipped from other installation sites may be set to either,
depending on where they were last used—check the status of the line cord plug and
switch before attempting to connect to AC. See instructions below (Figure 2.40).
1. A visual
inspection of
the plug will
indicate 200 or
400 VAC
status. Modify
as necessary for
your site—as a
delta load with
safety ground,
the plug has no
neutral.
2. Remove the
ballast cover to
access and read
the Input Power
Range Switch.
3. Toggle the
switch left for
use with 200
VAC supplies,
or toggle right
for 400 VAC
supplies.
4. Attach the
ground lug to
Earth Ground.
5. Re-install the
ballast cover.

Connect all 4 ballast
cables—two DC
power cables, and 2
communication/control cables—to the rear of the projector and to the lamp ballast.
Refer back to Figure 2.1.
