LCD displays are according to the exact load and battery capacity.
Turn to bypass mode under the following two conditions:
1. Turn off the UPS in line mode while start the bypass output.
2. Overload in line mode.
NOTE: When UPS is working in bypass mode, it has no back up function.
4.5.2 Line mode
LED indications on front panel in line mode are as following: The inverter green LED is on.
When input AC mains is in line with the working conditions, UPS will work in line mode.
4.5.3 Battery mode
LED indications on front panel in battery mode are as following: both the inverter green LED and battery yellow
LED are on, the buzzer beeps once every 4 seconds. The warning red LED is on when beeping.
When the mains power down or instable, UPS will turn to battery mode at once.
4.5.4 ECO mode
LED indications on front panel on ECO mode are as following: both the inverter green LED and bypass yellow
LED are on.
When the input mains meets the input range of the ECO mode and start the ECO function, the UPS will works
on ECO mode. If input AC mains exceeds the range of ECO several times in a row in a minute but stays in
inverter input range, UPS will work on AC inverting mode automatically.

Fault mode (LCD interface on which the fault code display)
When UPS has fault. The warning LED is on and the buzzer beeps. UPS will turn to fault mode. UPS cuts off
the output and LCD display fault codes. At the moment, you can press the mute key to make the buzzer stop
beeping temporarily to wait for maintenance. You can also press the OFF key to shut down the UPS when
confirm that there is no serious fault.
NOTE: As for corresponding information of the fault code, please refer to chapter 6.1
NOTICE:
★The following process must be performed if UPS is connected with generator:
★First turn on generator, after it runs stably connect output power of generator to UPS input terminal,
then turn on UPS. After UPS turned on, please connect load one-by-one.
★It is recommended that the generator capacity is as twice as UPS rated capacity
★You’d better not use the ECO mode when the quality of the input AC mains is not good.
5 MAINTENANCE
Only minimum maintenance is required for this series of UPS. The battery is sealed lead acid maintenance free.
It only needs to be kept charging to obtain the expected life. Whether it is started or not, the UPS would charge
batteries once it is connected to mains and provide protection for over-charging and deep discharging.
5.1 Battery maintenance
1. It is recommended that the batteries are manually charged or discharged once every three or four months if
UPS has not been used for a long time or the power is long-term uninterruptible. The battery will be fully
discharge to low-voltage protection shutdown. Then it needs to be fully charged once.
2. In high temperature area, batteries should be manually charged and discharged once every two months.
The process is the same as that said above.
3. Under normal circumstances of using, the battery working life is three to five years. If you find that the
battery do not act well such as obviously shortening of backup time, too much imbalance on battery voltage
so on, the battery should be replaced as soon as possible, which must be performed by qualified
personnel.
4. When replace battery, it is recommended to change battery all together instead of changing separately.
NOTICE:
★Before replacing batteries, first please turn off the UPS and break off the mains. Remove your metallic
adornment such as finger ring, watch and so on.
★When replace batteries, please use the screwdriver with insulating handle. Do not lay the tools or
metallic goods on the battery.
★Never reverse or short circuit between the battery anode and cathode.
