Online Mode
When the AC input is within the acceptable range and you press the ON/OFF button ( ) to turn
on the UPS, the UPS will operate in online mode and supply stable output to the loads through the
main input, AC-DC (PFC) and DC-AC (inverter) circuit.
Battery Mode
When (1) there is no AC input and you press the ON/OFF button ( ) to turn on the UPS

or (2)
the UPS runs in online mode and detects that the AC input is out of the acceptable range, the UPS
will operate in battery mode and supply stable output to the loads through the battery, AC-DC (PFC)
and DC-AC (inverter) circuit.

for details. The cold start function is not available when
you use lithium-ion batteries.
ECO Mode
After powered on, the UPS will supply power through the inverter first, and then transfer to bypass
if the bypass source is within the acceptable range. Once the bypass source is out of the acceptable
range, UPS will transfer back to the inverter immediately to keep the output voltage and frequency
within the acceptable range. Note that ECO mode is only applicable to single UPS but not to parallel
UPSs.
Frequency Conversion Mode
In this operation mode, the loads are always fed by the inverter. The output frequency is fixed at
50 Hz or 60 Hz depending on the output frequency setting.
The bypass path is disabled during this operation mode because the inverter is not tracking the
bypass input frequency. Note that frequency conversion mode is only applicable to single UPS but
not to parallel UPSs.
