3-6. Operating Mode Description
When pressing “ON/MUTE” button, if battery
voltage is within acceptable range, “ON” will
flash until the UPS is turned on.
When the input voltage is within acceptable
range, UPS will provide pure and stable AC
power to output. The UPS will also charge the
battery at online mode.
Energy saving mode:
When the input voltage is within voltage
regulation range, UPS will bypass voltage to
output for energy saving.
When input frequency is within 40 Hz to 70 Hz,
the UPS can be set at a constant output
frequency, 50 Hz or 60 Hz. The UPS will still
charge battery under this mode.
When the input voltage is beyond the
acceptable range or power failure and alarm is
sounding every 4 second, UPS will backup
power from battery.
When input voltage is within acceptable range
but UPS is overload, UPS will enter bypass
mode or bypass mode can be set by front
panel. Alarm is sounding every 10 second.
UPS is powered off without output power, but
the battery still can be charged.
