SWITCH
Set the input voltage select switch to 115 or 230 to match the AC line voltage. See
Figure 4 for switch location.
ATTENTION: Change slide switch settings only when the drive is
disconnected from the AC line voltage. Make sure line voltage is set to its
correct position. If the switch is improperly set to a lower voltage position, the
motor will not run at full voltage and may cause transformer damage. If the
switch is improperly set to a higher voltage position, the motor will overspeed,
which may cause motor damage.
