change motor voltage setting if line voltage is 230 volts, or if
you have a single voltage motor.
NOTICE: Never wire a 115 volt motor to a 230 volt line.
NOTICE: Wire TEFC motors according to wiring diagram
in junction box on motor. Be sure motor is connected for
correct line voltage.
NOTICE: Wire 3-Phase motors according to wiring
diagram on motor. Be sure motor is connected for
correct line voltage.
