The user must reposition the two metal jumpers on the terminal strip for
220/240V AC operation. Jumper positions for both 120V AC and 220/240V
AC operation are shown at the terminal strip (Figure 3-36).

In addition to repositioning the jumpers for 220/240V AC operation, the main
AC fuse of the System Power Supply must be changed. The Power Supply is
shipped with a 1 amp slow-blow fuse installed to accommodate 120V AC
operation. When the Power Supply is to operate on 220/24V AC, the 1 amp
fuse must be removed and the 0.5 amp fuse, shipped separately with the Power
Supply, must be installed.

AC input line connections are made to L1 and L2. (L2 is the high side of the
AC line; L2 is the low side). No connection is made to the equipment ground
terminal when the grounding configuration illustrated in Figure 3-7 is used.
Also see the last paragraph under “Incoming AC Wiring Guidelines” (Section
titled Incoming AC Wiring Guidelines).
