ETILIZE UPS1500RM2U, Installation Manual

Page: 6 / 44

Operating Mode Description LCD Display
ECO Mode When the input voltage is within voltage regulated
range, UPS will power the output directly from the
mains. ECO is an abbreviation of Efficiency Corrective
Optimizer. In this mode, when the battery is fully
charged, the fan will stop working to save energy
Buck Mode when
AC is normal When the input voltage is higher than the voltage
regulation range but lower than high loss point, the
buck AVR will be activated
Boost mode when
AC is normal When the input voltage is lower than the voltage
regulation range but higher than low loss point, the
boost AVR will be deactivated
Battery Mode When the input voltage is beyond the acceptable range
or power failure and alarm is sounding every 10 seconds,
UPS will backup power from battery
Standby Mode UPS is powered off and no output supply power, but can
still charge batteries
Fault Mode When a fault occurs, the ERROR icon and the fault code
will be displayed
