The display panel in utility power mode is shown in the following diagram. The utility
power LED and the INV LED are turned on.
If the battery LED is turned on and the utility power LED flashes, it indicates the voltage
or frequency of the utility power has exceeded the normal range, the UPS operates in
battery mode.
2) If output overloaded, the warning LEDs will be turned on and alarm will keep twice
every second. You should get rid of some unnecessary loads one by one to decrease
the loads connected to the UPS less than 90% of its nominal power capacity.
�
Note: Please follow the following steps to connect the generator: Activate the generator
and wait until the operation is stable before supplying power of the generator to the UPS
(be sure that the UPS is in idle mode). Then turn on the UPS according to the start-up
procedure. After the UPS is turned on, then the loads can be connected to the UPS one
by one.
�
The power capacity of the AC generator should be at least twice of the UPS capacity.
