 ECO Mode: On-line UPS enters Economy mode. The UPS will enter bypass mode according to thresholds for

input voltage. Once the utility voltage exceeds thresholds, the UPS will supply battery power to its loads.

Users can configure exclusive days and exclusive time to for UPS when to not enter ECO mode.

 Manual Bypass: The Online UPS enters Manual Bypass mode due the Manual option being enabled. The

UPS will be forced to provide utility power to its equipment.

 Insufficient Inverter Power: There is no enough capacity of the inverter’s power. UPS cannot back to line

mode from bypass mode.

 Redundancy Lost：The quantity of UPS modules has no enough power to be complete redundancy; UPS

has no complete fault-tolerant ability.

 EPO: The function of EPO (Emergency Power Off) has been activated; UPS output power was turned off.

 Voltage: The output voltage that the UPS is supplying to the connected equipment.

 Frequency: The output frequency that the UPS is supplying to the connected equipment.

 Load: The power draw of the connected equipment expressed as a percentage of the total load capacity. This is

displayed as watts on some UPS models.

 Current: The output current of the UPS which is supplying to connected equipment.

 Active Power: The capacity of the circuit for performing work in a particular time.

 Reactive Power: Reactive power is needed in an alternating-current transmission system to support the transfer

of real power over the network. In alternating current circuits, energy is stored temporarily in inductive and

capacitive elements, which can result in the periodic reversal of the direction of energy flow. The portion of power

flow remaining, after being averaged over a complete AC waveform, is the real power; that is, energy that can be

used to do work. On the other hand, the portion of power flow that is temporarily stored in the form of magnetic or

electric fields, due to inductive and capacitive network elements, and then returned to source, is known as reactive

power.

 Apparent Power: The product of the current and voltage of the circuit.

 Power Factor: The radio of the active power flowing to the load, to the apparent power in the circuit. In an electric

power systems, a load with a low power factor draws more current than a load with a high power factor for the

same amount of useful power transferred.

 NCL Outlet: Displays the present status of the NCL outlet.

 On: This outlet is turned on and supplying power to the connected equipment.

 Off: This outlet is turned off and is not supplying power to the connected equipment.

 Pending On: This outlet is going to turn on following an action such as a scheduled turn on.

 Pending Off: This outlet is going to turn off following an action such as a scheduled turn off.

Battery

 Status: Displays the present status of the battery packs.

 Fully Charged: The batteries are at 100% capacity.

 Discharging: The UPS is supplying battery power to support the load. This is caused by a utility power failure

or battery test.

 Charging: The batteries are charging.
