devices to the programmable outlets and critical devices to the general
outlets. During power failure, you may extend the backup time to critical
devices by enabling the programmable outlets.
1. With the UPS on-line switch on the load devices one by one. The
LCD display panel will display the load level by 0-25%, 26-50%,
51-75% and 76-100%.
2. If the UPS is overloaded the audible alarm will beep twice every
second and the LCD display panel will display "OVERLOAD".
3. When the UPS is overloaded remove some load immediately.
4. When the UPS is in on-line mode, and the overload time exceeds
the duration listed in the specification, the UPS will
automatically transfer to bypass mode. At this time, if the bypass
is enabled, the UPS will supply power to the load via bypass. If
the bypass function is disabled, or the input voltage is not within
the bypass acceptable range, the UPS will cutoff power to the
load. After the overload is removed the UPS will return to on-line
mode.
5. After repetitive overloads, the UPS will be locked in bypass mode.
Remove excess loads from the UPS output. Then restart the UPS.

5.4 The UPS in Battery Mode

1. When the input voltage is not within the acceptable range or there
is a mains failure the UPS will enter battery mode. The batteries
will continue to provide an uninterrupted supply of energy to the
load.
2. When the UPS is in battery mode the LCD display panel will
display the battery level by 0-25%, 26-50%, 51-75% and 76-100%
and the battery voltage. The audible alarm will beep according to
the battery capacity. Normally, the audible alarm will beep once
every four seconds. When the battery voltage drops to low battery
voltage level, the audible alarm will beep once per second and the
UPS will automatically shut down. At this time, users could switch
off any non-critical loads to disable the shutdown alarm and pro-
long the backup time. If no more load can be removed at this time,
