8. Set the voltage in the Power Distribution Unit (PDU) as follows:
a. Check the supplied voltage at Power Distribution Box.
Eight (8) levels of input RATING voltage (480, 460, 440, 415, 400, 380, 208, 200V) can be handled.
Input Voltage 208 V or 200 V can not be used for systems having a 350 mA/120 kV output.
For the System installed in the U.S.A., only 480V can be used as a PDU input voltage.
b. Remove the plastic cover from the transformer coupling plate ; See Illustration 3–2 (E).
c. Set the PDU input RATING voltage according to the appropriate setting shown in Illustration 3–3  Illustra-
tion 3–10.
The voltage is set by metal tap plates on the transformer coupling plate. See Illustration 3–2 (F).
E. REMOVE THE PLASTIC COVER
