 L: Low voltage point for bypass. The setting range is 176V ~ 209V when the UPS is HV system. The
setting range is 96V ~ 110V when the UPS is LV system.
 H: High voltage point for bypass. The setting range is 231V ~ 264V when the UPS is HV system.
The setting range is 139V ~ 146V when the UPS is LV system.
 Bypass FRE 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.
 N Line Check: Check if neutral line is correctly connected or not.
 Disable: Disable the neutral loss detection function. The UPS will not detect the neutral loss or

 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 voltage + 5V) to
(Rated output voltage + 11V). “Rated output voltage + 5V” is default setting.
 ECO FRE Range: Set the ECO frequency range. The setting range is from 48Hz to 52Hz when the UPS
is 50Hz system and from 58Hz to 62Hz when the UPS is 60Hz system.
