 Current: The current of the utility power supplied to the UPS.

 Power Factor: The radio of the real power flowing to the UPS, to the apparent power of utility power. In an UPS

system, a UPS with a low power factor draws more current than a UPS with a high power factor for the same

amount of useful power transferred.

Bypass

 Status: Displays the present status of bypass circuit. In bypass mode, the UPS will provide the power from bypass

input to the connected equipment directly.

 Normal: The power quality of bypass circuit is normal.

 Blackout: There is no input power being supplied in bypass circuit.

 Over Voltage: The input voltage of bypass is higher than an acceptable threshold.

 Under Voltage: The input voltage of bypass is lower than an acceptable threshold.

 Frequency Failure: The frequency of bypass is out of tolerance.

 Power Failure: The power of bypass is not qualify due to other power noise and distorted conditions.

 Wrong Phase Sequence: The sequence of phases in bypass is different than utility input.

 Overload: Output power consumption exceeds the power rating of UPS.

 Extended Overload: The duration of overload has expired.

 Voltage: The voltage of the bypass supplied to the UPS.

 Current: The current of the bypass supplied to the UPS.

 Frequency: The frequency of the bypass supplied to the UPS.

 Power Factor: The radio of the real power flowing to the bypass, to the apparent power of bypass. In an UPS

system, 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.

Output

 Status: Displays the present status of the output power the UPS is supplying to connected equipment.

 Normal: The output power is normal.

 Bypass: The UPS has switched to bypass mode and the utility power is being supplied directly to the

connected equipment bypassing the UPS circuitry.

Note: Bypass mode is only applicable in Online Series UPS units.

 No Output: There is no output from the UPS. The UPS is switched off.

 Short Circuit: There is a short circuit on the UPS output. This causes the UPS to stop supplying output power.

 Boost: The utility voltage is below the regular voltage range. The UPS is increasing the output voltage closer

to normal.

 Buck: The utility voltage is beyond the regular voltage range. The UPS is decreasing the output voltage

closer to normal.

Note: The Boost and Buck function are only available on a UPS with AVR; only high-end units with AVR have

a Buck feature. The UPS uses the AVR function to improve the utility voltage and supplies the power to its

connected equipment within a narrow range.

 Overload: The present load exceeds the load threshold of the UPS. Remove some equipment from the UPS

to reduce the load.
