regulated range, the UPS powers the output directly
from the mains. When the battery is fully charged in
this mode, the fan stops working to save energy.
Buck Mode
(When AC is
normal)
When the input voltage is higher than the voltage
regulation range, but lower than the high loss point,
the buck AVR (automatic voltage regulation) is
activated.

Description
LCD Panel
Boost Mode
(When AC is
normal)
When the input voltage is lower than the voltage
regulation range, but higher than the low loss point,
the boost AVR (automatic voltage regulation) is
activated.
Battery Mode When the input voltage is beyond the acceptable
range or when a power failure takes place and the
alarm is sounding every 10 seconds, the UPS
switches to backup power from the battery.
Standby Mode In this mode, the UPS is powered off and no outputs
are supplied power, however, the unit can still charge
the batteries.
Fault Mode When a fault occurs, the ERROR icon and the fault
code will be displayed.
UPS Settings
There are three parameters used for setting up your
UPS.
Parameter 1 is for selecting available programs for
your UPS system. See the remainder of this topic for
program details.
Parameter 2 is the setting options or values for each
program.
If another level of attenuation is available from
Parameter 2, the screen changes to show Parameter
2 and Parameter 3 as shown.
NOTE:
The following tables refer to these parameters as
Interface (Parameter 1) and Setting (Parameter 2) or
(Parameter 3), respectively.
Enter Settings mode before performing the following configurations. To enter the UPS settings mode, your
UPS needs to be OFF. With the unit off, press and hold the Select button for 5 seconds.
