2.6 Operating Mode Description

Operating Mode Description
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 When the input voltage is higher than the voltage
AC is normal regulation range but lower than high loss point, the
buck AVR will be activated
Boost mode when When the input voltage is lower than the voltage
AC is normal 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

Cause
The AC input power is not
connected
The AC input is connected to the
UPS output
EPO function is activated
and the warning
Line and neutral conductors of UPS
input are reversed
and the warning
The external or internal battery is
incorrectly connected
Battery voltage is too high or the
charger is faulty
Battery voltage is too low or the
charger is faulty
and the warning
UPS is overloaded
The UPS automatically shut down
due to an overload at the output
The UPS automatically shut down
because of a short circuit on the UPS
A UPS internal fault has occurred

and battery voltage is less than
10V/PC
Solution
Check if input power cord firmly connected to
the mains
Plug AC input power cord to AC input correctly
Set the circuit in closed position to disable EPO
function.
Rotate main power socket by 180° and then
connect to UPS system
Check if all batteries are connected
