3.2 UPS Operation
Turn on the UPS with utility power supply (in AC mode)
1) After power supply is connected correctly, set the breaker of the battery pack at “ON” posi
-
tion. Then set the input breaker at “ON” position. At this time the fan is running and the UPS
supplies power to the loads via the bypass. The UPS is operating in Bypass mode.
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 UPS. To protect your pre-
cious devices, you should turn on the UPS. Refer to next step.
2) Press and hold the “ON” button for 0.5s 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.
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.
2) Press and hold the “ON” button for 0.5s 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.
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 consump-
tion of this kind of loads is too big.
3) If the UPS is overloaded, the buzzer will beep twice every second.
4) When the UPS is overloaded, 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 automati-
cally transfer to Bypass mode. After the overload is removed, it will return to AC mode. If the
overload time is over acceptable time listed in spec at Battery mode, the UPS will become fault
status. 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.
