 Frequency Working Mode: Smart App Online series supports two frequency modes: Follow-up and Fixed. In

the Follow-up mode, the UPS supplies power based off of the utility frequency. If utility frequency varies and is out

of tolerance, the UPS supplies battery power with a fixed frequency to avoid supplying the connected equipment

an improper frequency. The fixed frequency depends on the utility frequency detected as the UPS is powering up.

In Fixed mode, the UPS supplies power at a fixed frequency with no regard to utility frequency. When the input

frequency is unstable such as with power supplied by generators, set the UPS to fixed mode to supply power with

a stable frequency.

The UPS can be set to fixed mode if the equipment needs a different frequency from the utility power. For

example, the equipment is rated at 50 Hz but utility frequency is at 60 Hz.

 Follow-up Tolerance: Sets the acceptable range of the output frequency on the Follow-up mode.

 Fixed Frequency: Sets the fixed value of the output frequency on the Fixed mode.

Caution: The wrong frequency settings may damage the connected equipment. Make sure the selected frequency

is correct for the connected equipment. An alert warning message will remind you of the following conditions:

 The frequency mode has changed from the Follow-up mode to the Fixed mode, and the fixed frequency is

not equal to the utility frequency.

 The frequency mode is Fixed mode and the fixed frequency is going to be changed.

 ECO Mode: The UPS will enter bypass mode according to the utility voltage if it is in range of thresholds or the

utility frequency is within 3Hz of the utility frequency. If the utility voltage or the utility frequency exceeds

thresholds, the UPS will supply battery power to its loads.

If this threshold is set to 10% and the current utility voltage is 120 V, the UPS will enter bypass mode as long as

the utility voltage within the range of 108 V ~ 132 V. Once the voltage threshold is exceeded, the UPS will supply

battery power to its loads.

Caution: Once the UPS is allowed to enter the Fixed mode, Generator Mode or Manual Bypass when the UPS is

in the ECO mode, the UPS will leave ECO mode.

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

 Exclusive Days: Sets the days for UPS not to enter ECO mode.

 Exclusive Time: Sets the time period for UPS not to enter ECO mode.

Power Failure Condition

When the utility power exceeds specific thresholds, the UPS will supply battery power to the connected equipment.

 Utility Voltage Upper/Lower Bound: Before utility power is provided to the UPS, the UPS will detect whether

utility voltage exceeds the threshold. If utility voltage exceeds the threshold, the UPS will supply battery power to

the connected equipment.

 Output Voltage Upper/Lower Bound: Before the UPS uses utility power as its output power, the UPS will detect

whether utility voltage exceeds the threshold. If the utility voltage exceeds the threshold, the UPS will supply

battery power to connected equipment.

Note: High/Low Utility Voltage Threshold & High/Low Output Voltage Threshold settings only come into

effect after a restart of the UPS.

 Frequency Upper/Lower Bound: When the utility frequency exceeds the threshold, the UPS will supply battery

power at a fixed frequency to the connected equipment.
