3-4. Single UPS Operation
1. Turn on the UPS with utility power (in AC mode)
1) After power supply is connected correctly, set the breaker of the battery pack at
“
ON
”
position (this
step is only necessary for external battery). Then set the line input breaker, bypass breaker &
output breaker to
“
ON
”
position. At this time the fan is running, and the UPS enters power on
mode for initialisation, several seconds later, UPS operates in Bypass mode and supplies power to
the load via the bypass.
NOTE:
When UPS is in Bypass mode, the output voltage will directly power from utility after you
switch on the input breaker. In Bypass mode, the load is not protected by the UPS. To protect your
precious devices, you should turn on the UPS. Refer to next step.
2) To
uch “CONTROL” and select “UPS on/off” icon. It will show “Turn on UPS?” in screen and select
“Yes”.
Refer to On/Off UPS screen.
3) A few seconds later, the UPS will enter into AC mode. If the utility is abnormal, the UPS will operate
in Battery mode without interruption.
NOTE:
When the UPS running out battery, it will shut down automatically at Battery mode. When the
utility is restored, the UPS will auto restart in AC mode.
2. Turn on the UPS without utility power supply (in Battery mode)
1) Make sure that the batteries are connected correctly at UPS

terminals and the breaker
of the battery pack is at

position.
2) Press the
“
SERVICE START
”
button to set up the power supply for the UPS. UPS will enter to
power on mode. After initialisation, UPS will enter to No Output mode.
3) A few seconds later, the UPS will be turned on and enter to Battery mode.
3. Connect devices to UPS
After the UPS is turned on, you can connect devices to the UPS.
1) Turn on the UPS first and then switch on the devices one by one. The LCD panel will display total
load level.
2) If it is necessary to connect the inductive loads such as a printer, the in-rush current should be
calculated carefully to see if it meets the capacity of the UPS, because the power consumption of
this type of load can be high.
3) If the UPS is overload, the buzzer will beep twice every second.
4) When the UPS is in overload, please remove some loads immediately. It is recommended to have
the total loads connected to the UPS less than 80% of its nominal power capacity to prevent
overload for system safety.
5) If the overload time is reached in the UPS spec at AC mode, the UPS will automatically transfer to
Bypass mode. After the overload is removed, it will return to AC mode. If the overload time is
reached in the UPS spec during Battery mode and if bypass is enabled, the UPS will power to the
load via bypass. If bypass function is disabled or the input power is not within bypass acceptable
range, it will cut off output directly.
4. Charge the batteries
1) After the UPS is connected to the utility power, the charger will charge the batteries automatically
except in: battery mode, during battery self-test, overload or battery high voltage.
2) Suggest charging batteries at least 10 hours before use. Otherwise, the backup time may be
shorter than expected.
5. Battery mode operation
1) When the UPS is in Battery mode, the buzzer will sound according to different battery capacity. If
the battery capacity is more than 25%, the buzzer will beep once every 4 seconds. If the battery
