Parameter 2: Output Frequency
Setting the output frequency. You may choose following three options
in parameter 2:
50.0Hz: The output frequency is setting for 50.0Hz.
60.0Hz: The output frequency is setting for 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 default setting.
Parameter 3: Frequency mode

CF: Setting UPS to CVCF mode. If selected, the output frequency will
be fixed at 50Hz or 60Hz according to 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 setting
in parameter 2. If 50 Hz selected in parameter 2, UPS will transfer to
battery mode when input frequency is not within 46~54 Hz. If 60Hz
selected in parameter 2, UPS will transfer to battery mode when input
frequency is not within 56~64 Hz.
*If Parameter 2 is ATO, the Parameter 3 will show the current frequency
