Bypass mode (bYPA)
The LCD display in bypass mode is shown as
Figure 9. The “bYPA” string indicates the UPS
working in the bypass mode. The UPS beeps once
every 2 minutes in bypass mode.

Battery mode (bATT)
The LCD display in battery mode is shown as
Figure 8. The “bATT” string indicates the UPS
working in the battery mode. If the function of
battery remain time is set to enable, the “bATT”
string and battery remaining time (in minutes or
seconds) would display in turn every 2s.
When the UPS is running in battery mode, the
buzzer beeps once every 4 seconds. If the ON
button on the front panel is pressed for more
than 1 second, the buzzer will stop beeping (in
silence mode). Press the ON button once again for
more than 1 second to resume the alarm function.

No output mode (STbY)
The LCD display in No output mode is shown as
Figure 10. The “STbY” string indicates UPS
working in the No output mode.

Emergency Power Off (EPO)
The EPO is also referred to as the Remote Power
Off (RPO). On the LCD display, the word “EPO”
is presented in the same position as the
output voltage.
The EPO is a specific status in which the UPS will
shut off the output and send out an alarm. The
EPO status must be reset before turning off the
UPS. The OFF button will not turn off the UPS
during an EPO status.

Economy mode¬ (ECO)
ECO mode is also referred to as high-efficiency
mode. You must turn the UPS on in ECO mode.
Output power is supplied from mains power
directly via an internal filter while the mains
power is within a certain range, so high-efficiency
performance is achieved in ECO mode.
Once the mains power is lost or out of range,
the UPS transfers to battery mode, and the load
is supplied continuously by the battery.
1. ECO mode is enabled through the LCD setting
or the software (WinPower, etc.).
2. The transfer time of the UPS output from
ECO mode to battery mode is less than 10
milliseconds. It is suggested to take this into
account when applying sensitive loads.

Constant Voltage Constant Frequency
mode (CVCF)
In Constant Voltage Constant Frequency (CVCF)
mode, also known as converter mode, the UPS
works in a frequency free-run with a fixed output
frequency (50Hz or 60Hz). Once the mains are lost
or abnormal, the UPS transfers to battery mode,
and the load is supplied continuously by the battery.
1. CVCF mode is enabled through the LCD setting
or the software (WinPower, etc.).
2. The normal power rating is derating to 60% in
converter mode.
4 1 10 Fault mode
When a fault occurs, (see Table 10), the
corresponding fault string is shown on the LCD
display to indicate the status of the UPS, and the
background light turns to red. For example,
“SHOR” is shown when the connected load or the
UPS output is in short-circuited, as shown on the
LCD display below in Figure 11.
