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
not.
Auto: The UPS will automatically detect 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 is
restored and detected, the alarm will be muted automatically and the UPS will go back to normal
mode automatically.
CHE: The UPS will detect the neutral loss or not only when first commission. 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. Please be sure to enter this selection and re-start the UPS
again to mute alarm.

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 v 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.
