3-4. Single UPS Operation
1. Turn on the UPS with utility power (in AC mode)
1) After power mains is connected correctly, set the breaker of the battery pack to "ON" position (this
step only necessary for long-run model). Then set the line input breaker to "ON" position. At the
same time the fan will start running and the UPS will start initialization. In just a few seconds, the
UPS will supply power to the loads via the Bypass mode.
NOTE: When UPS is in Bypass mode, the output voltage will be directed from mains 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) Touch "CONTROL" and select" icon. It will show "On UPS?" in screen and select "Yes". Refer to
On/Off UPS screen.
3)
In just a few seconds, the UPS will enter into AC mode. If the mains is abnormal, the UPS will
operate in Battery mode without interruption.
NOTE: When the UPS runs out battery, it will shut down automatically in Battery mode. When the mains
is normalized, 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 two strings of batteries are connected correctly in order of "+,GND,-" terminals
and the breaker of the battery pack is at "ON" position.
2) Press the "
mode. After initialization, UPS will enter to "No Output mode"
3) In just a few seconds, the UPS will be turned on and enter into 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 of the load
should be calculated carefully to see if it meets the overload capability of the UPS. Any load more
than 150% over designed capacity the runtime will be less than 60ms
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 in AC mode, the UPS will automatically
transfer to Bypass mode. After the overloading was resolved, it will return back to AC mode. If the
overload time is over acceptable time listed in spec in Battery mode, the UPS will enter 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 entirely.
