LCD display Description
Line Mode
Outlets supplied with power. Batteries are charged.
Battery
The unit provides output power from battery.
ECO mode[1]
When the input voltage is within set range, UPS
bypasses input to output for energy saving. [1]
Bypass[2]
UPS bypasses voltage to output.
2
ENGLISH
Converter[3]
The UPS is set to a constant frequency of 50Hz or
60Hz if the input frequency is within range. [3]
Standby
Output is switched off. The batteries are charged.
EPO
Emergency Power Off – the UPS output is turned
off.
Fault
The UPS is in fault mode because of short-circuit on
the output.
Units defining the numeric value: percentage,
kilowatt, volt-ampere, minute, hertz

[1] ECO Mode offers higher efficiency in line mode, but transfer time is not guaranteed to be
0ms.
[2] When bypass is disabled, the UPS will not turn on to bypass in case of overload or fault.
[3] The load capacity will be derated to 60%. ECO Mode, Bypass Mode are disabled (regardless
of the settings)
[4]If ROO (Remote On/Off) is enabled, UPS can be turned on/off by the ROO port (opened
circuit turns off; closed circuit turns on). EPO (Emergency Power Off) only turns off the UPS’
output. After closing the circuit UPS needs to be manually turned on.
[5] UPS cannot detect the number of Battery Packs, so this setting is essential. If BP is 1-3, the
charger current is increased to 4A.
