Operating mode/status
Description
LCD display
LCD display
When the input voltage is within an acceptable range, the UPS will provide pure and stable
AC power to the output. The UPS will also charge the battery in AC mode.
AC mode
ECO mode
CVCF mode
Battery mode
Bypass mode
Description
When the input voltage is within the voltage regulation range and ECO mode is enabled, the
UPS will bypass voltage to the output for energy saving.
Operating mode/status
Description
LCD display
When the input voltage is within an acceptable range, the UPS will provide pure and stable
AC power to the output. The UPS will also charge the battery in AC mode.
Fault status
LCD display
Description
When input frequency is within 46 and 64Hz, the UPS can be set at a constant output
frequency of 50Hz or 60Hz. The UPS will still charge the battery while operating in this mode.
LCD display
Description
When the input voltage exceeds the acceptable range or during a power failure, the UPS will
start supplying power from the battery while the alarm will beep every 4 seconds.
LCD display
Description
When the input voltage is within the acceptable range and the bypass is enabled, turn off the
UPS in order to transfer the unit to Bypass mode. The alarm beeps once every two minutes in
this case.
Battery test
LCD display
Description
When UPS is in AC mode or CVCF mode, press and hold the Test key for 0.5 second. The
UPS will beep once and start performing the “Battery test”. The line between I/P and inverter
icons blinks while the diagnostics is in progress. This operation is used to check the battery
status.
