High-Efficiency
Mode
HE Mode Setting Select whether High-Efficiency mode is On or Off. If
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.
HE Mode Off
Free Run Mode Free Run Mode Select whether Free Run mode is On or Off. If enabled,
you must also select Bypass Disable or Bypass Enable.
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 60 Hz UPS is set to the factory
default window of ±5% before the UPS starts
regulating the frequency:
S The output frequency tracks the input frequency
exactly from 57 to 63 Hz.
S If input frequency is between 45 and 57 Hz, or
between 63 and 65 Hz, the output frequency is
regulated by the UPS to exactly 60 Hz (±0.5 Hz).
You are prompted to save this setting.
