UPS Operation
Turn on the UPS with Utility Power (in AC Mode)
1.
After the UPS is connected correctly to AC utility, set the breaker on the battery pack at
“ON” position.
2.
Set the input breaker to “ON” position.
3.
At this point the fan will be running and the UPS will supply power to the loads via the
bypass. The UPS is operating in Bypass Mode.
Note:
When the UPS is in Bypass Mode, the output voltage will directly power the load
from utility after you have switched on the input breaker. In Bypass Mode, the load is not
protected by the UPS. To protect your load devices you should turn on the UPS.
4.
Press and hold the “ON” button for 0.5 seconds to turn on the UPS. The buzzer will beep
once.
5.
A few seconds later the UPS will enter AC mode. If the utility power is abnormal, the UPS
will operate in Battery Mode without interruption.
Note:
When the UPS is running out of battery time it will shut down automatically at
Battery Mode. When the utility power is restored the UPS will auto restart in AC mode.
Turn on the UPS without Utility Power (in Battery Mode)
1.
Make sure that the breaker on the battery pack is in the “ON” position
2.
Press and hold the “ON” button for 0.5 seconds to turn on the UPS. The buzzer will beep
once.
3.
A few seconds later the UPS will be turned on and enter Battery Mode.
Connecting devices to the 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
the total load level.
2.
If it is necessary to connect inductive loads such as a printer, the in-rush current should be
calculated to see if it is less than the available capacity of the UPS. Power consumption by
inductive loads can easily exceed the available capacity during startup.
3.
If the UPS is Overloaded, the buzzer will beep twice each second.
