NOTE!
When UPS is in Bypass mode, the output voltage will be directed from mains
aer 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.
NOTE!
When the UPS runs out baery, it will shut down automacally in Baery
mode. When the mains is normalized, the UPS will auto restart in AC mode.
2. Turn on the UPS without ulity power supply (in Baery mode)
1) Make sure that the two strings of baeries are connected correctly
in order of ”+,GND,-” terminals and the breaker of the baery pack is at
“ON” posion.
2) Press the “ON” buon to set up the power supply for the UPS. UPS
will enter to power on mode. Aer inializaon, UPS will enter to “No

2) If it is necessary to connect the inducve loads such as a printer,
the in-rush current of the load should be calculated carefully to see if it
meets the overload capability of the UPS. If connected load is more than
150% of designed capacity, the runme will be less than 60ms.
3) If the UPS is overload, the buzzer will beep twice every second.

16
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 me is over acceptable me listed in spec in AC
mode, the UPS will automacally transfer to Bypass mode. Aer the
overload is resolved, it will return back to AC mode. If the overload me
is over acceptable me listed in spec in Baery mode, the UPS will enter
fault status. At this me, if bypass is enabled, the UPS will power to the
load via bypass. If bypass funcon is disabled or the input power is not
within bypass acceptable range, it will cut o output enrely.
4. Charge the baeries
1) Aer the UPS is connected to the mains and turned on in AC
mode, the charger will charge the baeries automacally except in baery
mode, during baery self-test, overload or when baery voltage is high.
2) It’s recommended to charge baeries for at least 10 hours before
operaon. Otherwise, the backup me may be shorter than expectaon.
5. Baery mode operaon
1) When the UPS is in Baery mode, the buzzer will sound according
to dierent baery capacity. If the baery capacity is more than 25%,
the buzzer will beep once every 4 seconds. If the baery voltage drops
to the alarm level, the buzzer will beep once every sec to remind users
that the baery is at low level and the UPS will shut down immediately.
Users could switch o some non-crical loads to disable the shutdown
alarm and prolong the backup me. If there is no more load to be switched
o, you have to prepare shutdown procedure to protect working data or
devices. Otherwise, there is a risk of data loss or load failure.
2) In Baery mode, users can press the Mute buon to disable the
buzzer.
3) The backup me of the long-run model depends on the external
baery capacity.
