2. Set the values in the [Freq Up]/[Freq Lo] items so that the upper value of the frequency
setting range limit is higher than or equal to the lower limit.

4.1.5 About the Wattage Limiter
The wattage limiter operates when trying to output power exceeding the rated power. When
the wattage limiter operates, the output voltage is suppressed until the active power per phase
is equal the value shown in Table 4-1 (reference value). While the limiter is working, the
icon is displayed and LIMIT LED illuminates.

Notes
----------------------------------------------------------------------------------------------------------------
 If the wattage limiter operates, suppress the output wattage to within the rated output
power by lowering the output voltage setting value.
 Active power (unit: W) is restricted by the wattage limiter, however, reactive power (unit:
var) is not restricted. Therefore, the apparent power (unit: VA) may exceed the rated
power depending on the power factor of the load. Set the output voltage so that the
apparent power does not exceed the rated power, regardless of the operation of the
wattage limiter.
 The value of the wattage limiter cannot be changed. To limit the output power to a value
that is lower than the rating, decrease the number of power units that are energized
through the power unit energization setting, or use the peak current limiter or the RMS
current limiter.
