Operating mode Description LCD Mode
Normal mode (On Line)
If the supply voltage is within tolerance, the UPS
supplies the loads with clean and stable voltage
with a sinusoidal shape. In this mode, the batteries
are charged.
ECO mode
Economy mode
If the supply voltage is within tolerance, the
supply voltage is supplied directly to the UPS
output. The inverter is in Stand-by mode, which
increases eciency and reduces operating costs.
Frequency converter mode
If the supply voltage frequency is within the range
of 40 ÷ 70Hz, it is possible to set a xed value of
the output voltage frequency of 50 or 60Hz. This
mode also charges the batteries.
Battery operation mode
In the event of a power failure or when the supply
voltage is out of tolerance, the UPS transfers to
battery operation. A beep is made every 4
seconds.
Bypass mode
If the mains voltage is within the acceptable
tolerance limits, but an overload or any other
event occurs, the UPS will switch to Bypass mode.
A beep is made every 10 seconds. In this mode,
the batteries are charged.
Stand-by mode In emergency mode, the UPS shows the error
code and the icons associated with the event.
Alarm In emergency mode, the UPS shows the error
code and the icons associated with the event.
