Setting
Parameter 2: Output frequency
To set the output frequency, choose any of the following
three options in parameter 2:
50.0Hz: The output frequency is set to 50.0Hz.
60.0Hz: The output frequency is set to 60.0Hz.
ATO: When selected, the output frequency will be set
according to the latest normal utility frequency. If it ranges
from 46Hz to 54Hz, the output frequency will be 50.0Hz.
If it ranges from 56Hz to 64Hz, the output frequency will be
set at 60.0Hz. ATO is the default setting.
Parameter 3: Frequency mode
Enables you to set the output frequency in either CVCF
mode or no CVCF mode. You may choose any of the
following two options in parameter 3:
CF: Sets the UPS in the CVCF mode. If selected,
the output frequency will be fixed at 50Hz or 60Hz according
to the setting in parameter 2. The input frequency could
range from 46Hz to 64Hz.
NCF: Sets the UPS to normal mode (not CVCF mode).
If selected, the output frequency will synchronize with the
input frequency within 46~54 Hz at 50Hz or within 56~64 Hz
at 60Hz according to the setting defined in parameter 2.
If 50 Hz is selected in parameter 2, the UPS will transfer
to battery mode provided the input frequency does not fall
within 46~54 Hz range. If 60Hz is selected in parameter 2,
the UPS will transfer to battery mode provided the input
frequency does not fall within the 56~64 Hz range.

Interface Setting
Parameter 2: Sets the acceptable low voltage
for bypass operation. Setting ranges from 110V to 209V,
with a default value of 110V.
Parameter 3: Sets the acceptable high voltage
for bypass operation. Setting ranges from 231V to 276V,
with a default value of 264V.
