equipment 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 Follow-up mode.
Fixed Frequency: Sets the fixed value of the output frequency on the Fixed mode.
Note: 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 Follow-up mode to 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.
Utility Power Failure Condition
When the utility power exceeds specific thresholds, the UPS will supply battery power to the connected
equipment.
High/Low Voltage Threshold: When the utility voltage exceeds the threshold, the UPS will supply
battery power to the connected equipment.
Note: This setting only comes into effect after a restart of UPS.
High/Low Frequency Threshold: When the utility frequency exceeds the threshold, the UPS will supply
battery power at a fixed frequency to the connected equipment.
Detected Sensitivity: When the UPS detects the utility voltage is out of range, the UPS will switch to
battery mode to protect the equipment plugged into the UPS. Low sensitivity has a looser voltage range
and the supplied power may vary more widely. The UPS switches to battery mode rarely and also saves
more battery power. The power from fuel generator may cause the UPS to switch to battery mode more
frequently, and the low sensitivity is recommended. High sensitivity allows the UPS to supply the more
stable power to equipments and switches to battery mode frequently.
Power Restore
When a utility power failure occurs, PowerPanel
shut down and power off after the specified remaining runtime is met or the batteries capacity are low. After
the utility power restores the UPS turns on automatically and supplies power to the computer. If the
computer bios is set to boot when power restores the computer will automatically restart.
The following settings are used to configure the UPS restore behavior:
Automatic Restore: When this option is enabled, the UPS will restore output immediately when the
utility power restores. When this option is disabled, the UPS will not restore output at that moment and
users have to turn it on manually at a later time.
Mandatory Power Cycle: When a shutdown sequence is initiated due to power failure, the connected
computers may be requested to shutdown once and the UPS will be also requested to turn off in a delay
time. If the utility power restores prior to an UPS off, the UPS also will turn off itself. In this circumstance,
