2) Press and hold the "ON" button for 1s to turn on the UPS and the buzzer will beep once.
3) A few seconds later, the UPS will enter to AC mode. If the utility power is abnormal, the UPS will
operate in Battery mode without interruption.
NOTE: When the UPS is running out battery, it will shut down automatically at Battery mode. When the
utility power 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 breaker of the battery pack is at "ON" position (only for long-run model).
2) Press and hold the "ON" button for 1s to turn on the UPS, and the buzzer will beep once.
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) Switch on the devices one by one and it will display total load level in LCD panel.
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 kind of loads is too big.
3) If the UPS is overload, the buzzer will beep twice every second.
4) When the UPS is 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 over acceptable time listed in 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
occurs 3 times in half hour, the UPS will be locked in Bypass mode. UPS can transfer to Line mode
only by manual restart. At this time, 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 or during battery self-test.
2) It's suggested to charge batteries at least 10 hours before use. Otherwise, the backup time may be
shorter than expected time.
3) The charging current can be changed from 1A to 6A via LCD or software. Please make sure that the
charging current is suitable to battery specification.
5. Battery mode operation
1) When the UPS is in Battery mode, the buzzer will beep according to different battery capacity. If the
battery capacity is more than 25%, the buzzer will beep once every 4 seconds. If the battery
voltage drops to the alarm level, the buzzer will beep quickly (once every sec) to remind users that
the battery is at low level and the UPS will shut down automatically soon. Users could switch off
some non-critical loads to disable the shutdown alarm and prolong the backup time. If there is no
more load to be switched off at that time, you have to shut down all loads as soon as possible to
protect the devices or save data. Otherwise, there is a risk of data loss or power failure.
2) In Battery mode, if buzzer sound annoys, users can press the Mute button to mute the buzzer.
3) The backup time of the long-run model depends on the external battery capacity.
