faulty, an interruption (less than
20 ms) occurs when the UPS

Item Description Default Value Value Range
Maximum
bypass voltage When the difference between the
bypass voltage and the rated
voltage exceeds the upper
threshold for the bypass voltage,
the system determines that the
bypass voltage is not normal and
that the bypass is unavailable.  When the voltage level is 380 V,
the value range is +10%, +15%,
+20%, and +25%. The default
value is +15%.
 When the voltage level is 400 V,
the value range is +10%, +15%,
and +20%. The default value is
+15%.
 When the voltage level is 415 V,
the value range is +10% and
+15%. The default value is
+10%.
Minimum
bypass voltage When the difference between the
bypass voltage and the rated
voltage exceeds the upper
threshold for the bypass voltage,
the system determines that the
bypass voltage is not normal and
that the bypass is unavailable.
