115/230V AC Input Power
The internal power supply can operate at 115 VAC or 230 VAC. There is no
user setting to select the input voltage because the power supply automati-
cally senses the input voltage. However, you must make sure that you have
the correct power cord plug and fuses installed for the line voltage you are
using (refer to Replacing Fuses, page 39).
AC Line Connectors
To make the AC line cord compatible with non-U.S. voltages, users must
install the appropriate connector on the power cord.
