Niveo Professional NUPS22-6000U - Manual (Page 22)

1) Bypass setting
Interface Description
1. Status (only available in bypass / AC mode)
1.1 Open/Forbid:
Open: Bypass allowed. When selected, UPS will run at Bypass
mode depending on bypass enabled/disabled setting.
Forbid: Bypass not allowed. When selected, it’s not allowed for
running in Bypass mode under any situations.
1.2 Enable/Disable
This option appears only when Bypass status is set to “Open”.
Enable: Bypass enabled. When selected, Bypass mode is
activated.
Disable: Bypass disabled. When selected, automatic bypass is
acceptable, but “manual bypass” is not available. “Manual bypass”
means users manually operate UPS to Bypass mode (for example,
in AC mode turning off the UPS to Bypass mode). Then, the UPS
will go to bypass mode but without output if it is turned off in AC
mode.
NOTE: The following items are only available in bypass mode:
2. HighLoss V: Set the acceptable high voltage for bypass. Setting
range is from (Rated Output Volt +11V) to 276V and the default
value is 264V.
3. LowLoss V: Set the acceptable low voltage for bypass. Setting
range is from 110V to (Rated Output Volt - 11V) and the default
value is 110V.
4. HighLoss F: Set the acceptable high frequency for bypass.
50 Hz: Setting range is from 51Hz to 54 Hz.
60 Hz: Setting range is from 61Hz to 64Hz.
The default value is 54.0Hz/64.0Hz.
5. LowLoss F: Set the acceptable high frequency for bypass.
50 Hz system: Setting range is from 46.0Hz to 49.0Hz.
60 Hz system: Setting range is from 56.0Hz to 59.0Hz.
The default value is 46Hz/56Hz.
2) ECO setting (only available or effective on bypass mode)
Interface Description
1. Status
Enable: Enable ECO Function
Disable: Disable ECO Function
If ECO function is disabled, voltage range and frequency range for
ECO mode still can be set, but it is meaningless unless the ECO
function is enabled.
2. HighLoss V: High voltage point in ECO mode. The setting range
is from +5% to +10% of the nominal voltage.
3. LowLoss V: Low voltage point in ECO mode. The setting range is
from -5% to -10% of the nominal voltage.
4. HighLoss F: Set low frequency point for ECO mode.
50 Hz system: Setting range is from 46Hz to 48Hz.
60 Hz system: Setting range is from 56Hz to 58Hz.
The default value is 48Hz/58Hz.
5. LowLoss F: Set high frequency point for ECO mode.
50 Hz: Setting range is from 52.0Hz to 54.0 Hz.
60 Hz: Setting range is from 62.0Hz to 64.0Hz.
The default value is 52.0Hz/62.0Hz.
