restored, the UPS will switch to normal operation immediately. This option can be used to prevent

frequent outage due to unstable utility power.

Bypass Condition

The Online UPS series supports the bypass function. When the UPS is in bypass mode, the utility power is

supplied directly to the connected equipment. To configure whether the UPS is allowed to enter or remain in

bypass mode in select from the following:

z Qualification:

This configures the qualifications the UPS uses to determine if it will enter bypass mode when a

UPS fault or overload occurs.

 Valid Volt. & Freq.: If the utility voltage is in range of the voltage thresholds and the utility frequency

is in range of the frequency tolerance, the UPS will enter bypass mode. Otherwise the UPS will stop

supplying output power.

 Valid Voltage: If the utility voltage is in range of the voltage thresholds, the UPS will enter bypass

mode. Otherwise the UPS will stop supplying output power.

 Never Bypass: If this option is selected, the UPS will not enter bypass mode and will stop supplying

output power.

z Mandatory: If this option is enabled, the UPS always enters bypass mode, due to a fault or overload,

even the utility voltage is outside of the normal range. Otherwise the UPS will stop supplying output

power.

Caution: The bad utility voltage on the bypass mode may damage the connected equipment.

z Manual: Determines whether to allow the UPS to enter Manual Bypass mode. If this option is enabled,

the UPS will be forced to enter bypass mode.

Caution: Make sure that the UPS is not using generator power or converted power. When the UPS

enters bypass mode, the UPS will use input power to supply to equipment. The unstable frequency of the

input power may damage connected equipment.

Caution: If this option is enabled, the UPS can’t function in the Generator mode.

z High/Low Utility Voltage Threshold: When a UPS fault or overload occurs, UPS will determine

whether to enter bypass mode according to range of thresholds fro utility power. If the utility voltage

exceeds thresholds, UPS will be forbidden to enter bypass mode and will stop supplying output power.

z Overload: This configures the ability of the UPS to switch to bypass mode and supply utility power when

the output is overloaded. Without this enabled the UPS will stop supplying power when overloaded.

z Switch Off: This determines whether the UPS will switch to bypass mode and supply utility power when

the UPS is switched off.

Battery

z Prevent Excessive Discharge: When the UPS uses the battery to supply power for output, a deep

discharge with a low load can shorten the battery life. If this option is enabled, the UPS will stop

supplying power after discharging for 4 hours to avoid a deep battery discharge.
