Parameter 3: Output voltage
You may choose the following output voltage in parameter 3:
208:
Presents output voltage is 208Vac
220:
Presents output voltage is 220Vac
230:
Presents output voltage is 230Vac
240:
Presents output voltage is 240Vac
02: Output frequency

Setting
60 Hz, CVCF mode
50 Hz, Normal mode
ATO
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
Setting output frequency at CVCF mode or not CVCF mode. You
may choose following two options in parameter 3:
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.
Note: If the UPS is set to CVCF mode, the bypass function will be disabled automatically.
But when a single UPS without parallel function is powered on with mains and before the UPS
finished the startup, there will be a few seconds of voltage pulse (same as the input voltage)
on the bypass output.
If you need to remove the pulse on this mode to protect your load better, you could contact the
dealer for help. For the UPS with parallel function, this pulse situation won’t happen.
03: Voltage range for bypass
Interface
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.
