5.1 Operation Modes

Online Mode

During online mode, the ONLINE LED (green) and the LOAD LED (green) il-

luminate. If loads are connected to the UPS, the Bar Graph LEDs (green) will

illuminate or flash to indicate the occupied rated capacity (%). For information

about the Bar Graph LEDs, please refer to 2.4 Front Panel. In online mode, the

connected loads are supplied by the utility AC power, and the UPS charges the

batteries as needed and provides power protection to the connected loads from

a variety of power line problems.

Battery Mode

When the UPS is operating during a power outage, the batteries provide DC

power, which maintains inverter operation to support the loads. During battery

mode, the ON BATT. LED (green) and the BATT. LED (green) illuminate, and

the Bar Graph LEDs (green) illuminate or flash to indicate the reaming battery

capacity. For information about the Bar Graph LEDs, please refer to 2.4 Front

Panel. You can use the UPSentry 2012 software (included in the provided CD),

SNMP card (optional), or ModBus card (optional) to monitor and estimate the

battery remaining capacity before or during an AC power failure. For more infor-

mation about the SNMP card (optional) or the ModBus card (optional), please
