Setting
Parameter 2: Output Frequency
Setting the output frequency. The following three options are
available in parameter 2:
50.0Hz: The output frequency is set at 50.0Hz.
60.0Hz: The output frequency is set at 60.0Hz.
ATO: If selected, output frequency will be decided according to
the latest normal utility frequency. If it is from 46Hz to 54Hz, the
output frequency will be 50.0Hz. If it is from 56Hz to 64Hz, the
output frequency will be 60.0Hz. ATO is the default setting.
Parameter 3: Frequency mode
Setting output frequency at CVCF mode or not CVCF mode. The
following two options are available in parameter 3:
CF: Setting UPS to 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 be from 46Hz to 64Hz.
NCF: Setting 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 in parameter 2. If 50 Hz is selected in parameter 2, the
UPS will switch to battery mode when the input frequency is not
within 46~54 Hz. If 60Hz is selected in parameter 2, the UPS will
switch to battery mode when the input frequency is not within
56~64 Hz.
*If Parameter 2 is ATO, the Parameter 3 will show the current
frequency.
Setting
Parameter 2: Set the acceptable low voltage for bypass. Setting
range is from 110V to 209V and the default value is 110V.
Parameter 3: Set the acceptable high voltage for bypass. Setting
range is from 231V to 276V and the default value is 264V.
Setting
Parameter 2: Set the acceptable low frequency for bypass.
50 Hz system: Setting range is from 46.0Hz to 49.0Hz.
60 Hz system: Setting range is from 56.0Hz to 59.0Hz.
The default value is 46.0Hz/56.0Hz.
Parameter 3: Set the acceptable high frequency for bypass.
50 Hz: Setting range is from 51.0Hz to 54.0 Hz.
60 Hz: Setting range is from 61.0Hz to 64.0Hz.
The default value is 54.0Hz/64.0Hz.
