Modes and warnings
Operation

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.

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,

Event description and troubleshooting
Event
Description
E11, E12, A62
Various issues related to batteries. Please check if batteries are connected
and they are in good condition.
E14
Issue related to the load. Check if there is no short-circuit or excessive load.
Test the UPS without the load.
E18, E19, A68
Issues related to overheating or fan failure. Please check that the fan is
rotating, ventilation holes are not covered and the ambient temperature is
within norm.
EPO

[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.
