Default Settings
Output Voltage Setting
O/P V Setting
To change the output voltage
• Select 208, 220, 230, or 240V for 240V models.
For 240V models:
You are prompted to save this setting.
O/P V= 230V
Input Voltage Tolerance
I/P Bypass Set
Select the input voltage tolerance range before the UPS
I/P Tol=+10%/-15%
goes to Battery mode: ±10%, +10%/-15%, or +15%/-20%.
You are prompted to save this setting.
Input Frequency
I/P F Setting
The factory-default is 50 or 60 Hz, ±5%. Select ±2% for
Freq Tol.=+/-15%
a narrower frequency range. Select ±7% for a wider
frequency range.
You are prompted to save this setting.
High-Efficiency Mode
HE Mode Setting
Select whether High-Efficiency mode is On or Off. If
HE Mode Off
enabled, you must also select the input voltage range:
±10% or ±15%.
While operating in High-Efficiency mode, the UPS
transfers to utility power when: 1) the input voltage is
outside ±10% or ±15% from nominal; 2) the input
frequency is greater than ±3%; or 3) the input line is
not available.
You are prompted to save this setting. If the setting is
not allowed, the LCD shows “I/P out limit” which means
the input voltage or frequency is not suitable.
Free Run Mode
Free Run Mode
Select whether Free Run mode is On or Off. If enabled,
Free Run On
you must also select Bypass Disable or Bypass Enable.
(Bypass Disable)
This selection defines how your UPS runs when the input
frequency (from the utility) is outside the selected frequency
tolerance (set via the I/P F Setting, above), but is inside the
maximum frequency limits the UPS can accept before
switching to Battery mode.
For example: If your 50 Hz UPS is set to the factory default
window of ±5% before the UPS starts regulating the frequency.
• The output frequency tracks the input frequency exactly from
47.5 to 52.5 Hz.
• If input frequency is between 45 and 65 Hz, the output
frequency is regulated by the UPS to exactly 50 Hz (±0.5 Hz).
You are prompted to save this setting.
Alarm Silence
Alarm Silence
Select whether Silence is On or Off. If enabled, the UPS
Silence Off
silences the alarm for an existing fault. If the UPS status
changes, the alarm beeps, overriding the previous alarm
silencing. The alarm does not silence if there is a low
battery condition.
