CVCF Mode

 (constant voltage and constant frequency function)

  Enable: CVCF function is enabled. The output frequency will be fixed at 

50Hz or 60Hz according to setting of “OP Freq.”. The input frequency could 

be from 46Hz to 64Hz.

  Disable: CVCF function is disabled. The output frequency will synchronize 

with the bypass frequency within 46~54 Hz for 50Hz system or within 

56~64 Hz for 60Hz system. Disable is the default setting.

Bypass Forbid:

  Enable: Bypass forbid is enabled. When selected, it’s not allowed for 

running in Bypass mode under any situations.

  Disable: Bypass forbid is disabled. When selected, UPS will run in Bypass 

mode depending on “Bypass at UPS off” setting. It is the default setting.

Neutral Line Check:

  Disable: Disable the neutral line check function. The UPS will not detect if 

the neutral line is loss or not. 

  Auto: The UPS will automatically detect if the neutral is lost or not. If 

neutral loss is detected, an alarm will be generated. If the UPS is turned on, it 

will transfer to battery mode. When neutral line is restored and detected, the 

alarm will be muted automatically and the UPS will go back to normal mode 

automatically. 

  Check: The UPS will automatically detect the neutral loss. If neutral loss is 

detected, an alarm will be generated. If the UPS is turned on, it will transfer 

to battery mode. When neutral is restored, the alarm will NOT be muted 

automatically and the UPS will NOT go back to normal mode automatically. 

  ISO Compensation: When UPS is connected to output isolation, it will 

compensate the output voltage.

Bypass at UPS off:

 Select the bypass status when manually turning off the 

UPS. This setting is only available when “Bypass forbid.” is set to “Disable”.

  Enable: Bypass enabled. When selected, bypass mode is activated.

  Disable: Bypass disabled. When selected, no output through bypass when 

manually turning off the UPS.

Bypass Voltage Range:

 Set the bypass voltage range.

  L: Low voltage point for bypass. The setting range is 176V ~ 209V.

  H: High voltage point for bypass. The setting range is 231V ~ 264V.

Bypass FREE Range:

 Set the bypass frequency range.

The acceptable bypass frequency range from 46Hz to 54Hz when UPS is 

50Hz system and from 56Hz to 64Hz when UPS is 60Hz system.

ECO mode:

 Enable/Disable ECO mode. Default setting is “Disable”.

ECO Voltage Range:

 Set the ECO voltage range.

  L: Low voltage point for ECO mode. The setting range is from “Rated 

output voltage – 5V” to “Rated output voltage - 11V”. “Rated output voltage 

– 5V” is default setting.

  H: High voltage point for ECO mode. The setting range is from “Rated 

output v 5V” to “Rated output v 11V”. “Rated output voltage 

+ 5V” is default setting.

ECO FREE Range: 

Set the ECO frequency range. The setting range is from 

46Hz to 54Hz when the UPS is 50Hz system and from 56Hz to 64Hz when 

the UPS is 60Hz system.
