 No Output Mode

The LCD display in No output mode is shown in the following diagram. The

information about the utility power, the battery level, the UPS output and the load

level could be displayed. The "STbY" string indicates the UPS is working in the

No output mode.

 Bypass Mode

Bypass mode means that the UPS provides the power through the internal

bypass way to load directly without any regulation. If the controller detects the

mains is abnormal, it will shut off the output to protect the load. The UPS bypass

voltage/frequency range and default output status (on/off) could be set by

communication software. However, UPS output power will be cut off if mains

input range exceeds the setting value.

The LCD display in bypass mode is shown in the following diagram. The

information about the utility power, the battery level, the UPS output and the load

level could be displayed. The UPS will beep once every 2 minutes in bypass

mode. The "bYPA" string indicates the UPS is working in the bypass mode.

 Line Mode

Line mode means that the mains input is rectified/converted by the AC/DC

section and then inverted to stable output by DC/AC section. In line mode, the

output is clean and good to the loads. If the mains get abnormal, the UPS will

transfer to battery mode without interrupt.

The LCD display in Line mode is shown in the following diagram. The

information about the utility power, the battery level, the UPS output and the load

level could be displayed. The "LINE" string indicates the UPS is working in Line

mode.

 Battery Mode

Battery mode means that the battery power goes through the DC/DC section to

the inverter (DC/AC) and get a stable backup output when the mains input is not

usable. If the mains input recovered, the UPS will transfer to line mode without

interrupt.

The LCD display in battery mode is shown in the following diagram. The

information about the utility power, the battery level, the UPS output and the load

level could be displayed. The "bATT" string indicates the UPS is working in the

battery mode.

When the UPS is running in battery mode, the buzzer beeps once every 4

seconds. If the ON-Button on the front panel is pressed for more than 1 second

again, the buzzer will stop beeping (in silence mode). Press the ON-Button once

again for more than 1 second to resume the alarm function
